only 65 bucks now :o

Which pump is best? There are 2 pump types on ebay. One has long foot rests and one has short foot rests. Are these better than the Benjamin?
-
The second one is just like the G6, you get an extra set of seals with it along with other stuff. I have one just like #2 that I ordered for a back up, I paid $63.95 plus $9.99 shipping, it put me to $80.

It was delivered in less than two weeks and has been working great. It came with a complete rebuild kit including the check valves and replacement filters. I have only been using it for about a month now so I can't speak to the durability.

That's it but mine was $63.95 plus the $9.99 shipping

none , just like the benjamins.

I got the same one when it was $59 + ship. ($70 total I think) about 6-7 months ago. A lot of us bought this pump. Some people got 2 of them because the price was so good. It's a decent pump. I have only used it 1/2 dozen times to fill the Disco's, but it's a great compliment to my 4500 tanks. It only takes a couple of dozen pumps to go from 1K to 1,900psi on a Disco (I never fill them to 2K because they shoot low until they get down to 1,850-1900). I don't plan to ever use this pump on the Condors that take 150-200 pumps. I bet I 'd have to use those extra parts the pump came with much sooner if I did...

I ordered one of these for $72.19.

I will post my opinion of how it compares with my old Benjamin when it arrives.

I can tell you it's the same exact one as my Barska pump.

thats great to hear... From what ive heard they are better and smoother running than the bejnjamin
-

hows the barska been so far
-
What kind of desiccant do these come with?
none , just like the benjamins.
These variants appear to have the inlet at the top - under the handle. Difficult to hook up a desiccant system, even more difficult to add a vendor supplied unit. The Benjamin style is easy to add either desiccant to its inlet.
What is the best? Any will work and all will have examples that fail. Unfortunately. :(
-
Just ordered one (the 2nd one) to keep as a backup pump. For that price figured "what the heck" :)
Jeff
-
yep, really cannot go wrong with a 72 dollar pump , even if you never use it LMBO
-
I just ordered one, as well. Will report back when it arrives either here or in the review sub-gate. This will be a back up to my Hill mk4 and also a field pump. No need to expose an expensive one when there is a cheaper one!
-
cool give a brief review in this thread, because most of us will never see it in the other gate ( overlook it
-
That's how I felt.... I already have a Benjamin pump and an Air Force pump and both of them work great, but I'm a firm believer in redundancy and for that price this will make a nice backup to the backup pump :)
Jeff
-
Same here, I got one of the Barska Winbest pumps a while back and I have been using it more than the Hill to see how long it will take to develop a problem. So far so good.
-

hows the barska been so far
The Barska has been great so far, but I have only used it less than 10 times, including today to top off both the Disco's. I have only pumped it to 1900psi to fill the Discos, so I don't know how it would hold up pumping the Mrod and Condors to 3K psi frequently. I use my 4500 tanks for the others.

makes sense ..

My pump shipped today :)
Jeff

I think my pump was shipped yesterday. The email from ebay says it should arrive between Feb 18 and Feb 24.

My pump shipped today :)
Jeff
Pump #4 Jeff? The backup to the backup to the backup pump? ;D Are you doing the same thing as me, storing stuff in the kids' rooms after they move out? I am running out of room to put all this stuff. I filled my office/man cave a few years back, and now and entire bedroom :)
Harry
-
Actually Harry I am starting to run out of space to store my air gun stuff but I think I can cram a little bit more in :)
Jeff
-
We can always find the space for a few more guns and accessories :) Finding the space for another safe though might be a bit more difficult in my case ;D
-
Might be time for a room addition. :D
-
No it's more like it's time to throw out a sofa or a piece of furniture but the wife won't have it :)

I just received the package this morning. It is a little oily, which is typical of products from China. The pressure gauge needs to be attached and screwed into the base of the pump, and that can be done without any tools.
The first problem was that the quick disconnect did not work with any of my Air Venturi male adapters (https://www.amazon.com/Air-Venturi-Quick-Disconnect-Female-Threads/dp/B004M37FYA/ref=pd_bxgy_200_2?_encoding=UTF8&pd_rd_i=B004M37FYA&pd_rd_r=NJYWN9EN7ZETCNC5WX8D&pd_rd_w=nHCvq&pd_rd_wg=quW9c&psc=1&refRID=NJYWN9EN7ZETCNC5WX8D). It worked with the MRodair match pistol adapter because that one is a one-piece design. The problem has to do with the male adapter cannot go deep enough into the female adapter on the pump to engage the lock. I find this to be a somewhat common problem with the Air Venturi male adapters. It is time to look into an alternative source of such adapters, or change the female part that comes with the pump to a Air Venturi one.
The pump itself seems to be of solid construction, including the folding legs. The folding legs are a great help for transporting the pump. Pump operation is okay, definitely not as smooth as the Hill Mk4 pump. Comparing to something that is at least 300% the price isn't exactly fair, however.
I was only able to connect the pump to the Mrodair precision air pistol. Pumping effort is no different from that of a Hill pump, but it seems to take more strokes. This can be just my imagination.
What I like about this $72 pump is that it is easy to service. The top unscrews to expose the inner pump tube for lubrication without tools. It also has an inline air filter (on the high pressure side) that is easy to service. The pump comes with a full service kit, but without silicone oil (that's okay, I have a big bottle of that!). The hose is long and flexible compared to the one that comes with Hill pumps, and it does not seem to take up many pumps to pressurize the hose itself.
All-in-all, it seems to worth every penny of the $72. I will test its long term reliability after getting replacement female disconnect adapter so I can use the pump on the guns that I use most.
-
wow, thanks soo much for the full rundown! Interesting because the fosters never seem to be a universal fit, and as a matter of fact theres as many as 4 variations out there.Not shocking this fits the chinese gun no problem.. Is there an easy way to add a dessicant filter?

Most of my Air Venturi male quick connect adapters do not work well with other female connectors. I am ordering another female adapter and see whether that will work with all my current male adapters.
As to adding a desiccant filter, the air intake is at the top of the outer tube, but not connected into the handle bar. In other words, air goes in through the gap between the tube top and the base of the handle bar. I suppose you can drill through the handle bar and use some tubing to connect the air intake to a container filled with desiccant with another opening on the other side. But that may affect the strength and integrity of the handle bar.
You can also look into this (https://www.amazon.com/Taousa-Airgun-Pump-High-Pressure/dp/B01D2RT3NM?th=1). It is known to have issues with the sponge and cotton "filters". Don't know whether it is advisable to put regular desiccant into this filter housing.
The thing about condensation and relative humidity is that with the same water content in air, and assuming temperature does not change much, water condenses in high pressure much more readily (https://www.physicsforums.com/threads/relative-humidity-and-dew-point-after-compression.712980/). This means that at each stage of a pump, water may condense and not get passed through to the next stage.
This is also echoed in a Shoebox discussion (http://forum.shoeboxcompressor.com/forum/archive/index.php/t-268.html).
Seeing that the bleed valve is lower than the hose connector, condensation is likely to be trapped at the bottom of the base of the pump. I don't know whether the condensation will come out of the bleed value, I have not observed that, yet. This is possibly due to the relatively low volume of the Mrodair air pistol reservoir and it was already at 2000 PSI before pumping.
-
Thanks for the review. I'm looking forward to receiving mine on Monday :)

My $72.19 pump arrived today from ebay.com/itm/262802571430
It works better than my Benjamin. I am happy with this purchase.
The manual is in color and the pictures are good. The China English is a little hard to read.
It came with 11 foam pieces that are 0.8 inches long and 0.35 inches in diameter and are obviously air filters. The manual does not mention them and I do not know how to install them.
If someone knows how to install these filters please tell me how.
Also please tell me if there is a video for this type of pump.
-
thats great to hear, hoping someone has figured out the moisture traps

Try here...same internals and parts > https://www.youtube.com/watch?v=qUZaRNthGKA (https://www.youtube.com/watch?v=qUZaRNthGKA)
The fiber filters goes to the fitting behind the female quick disconnect... if torqued tight, need to use channel locks and crescent wrench. The all purpose wrench that came with my pump slips. Metal is not harden, again fittings should only be snug because o-rings provide the sealing. On the filter fitting I reversed it so filter is now towards the guage so it's not in the way when connecting to the air rifle foster fitting and LDC.
-
Thank you VERY MUCH Bentong!!!

Received my pump today. The box was partially open when the FEDEX guy left it at my door and I was concerned that some pieces might be missing, but inspection revealed everything was there and in good shape. I wanted to try it out so I screwed in the air gauge and attempted to connect the pump to one of my disco rifles. I immediately found out that the female quick disconnect on the pump hose would not fully engage. I tried it on a couple of other rifles and it just wouldn't work. The problem was that the female disconnect would not allow the male adapters on the rifles to fully engage and lock into place. I went through my spare parts bin, found a replacement female disconnect and installed it on the pump hose. The hose now properly connected to all my rifles :)
My P-rod only had 1000 psi so I decided to fill it to 3000. The pump functioned smoothly and perfectly and in no time the P-rod was sitting right at 3000 psi. The gauge on the pump read 2800 psi but I went with the gauge on the P-rod. I was very impressed with how smooth and efficient the pump functioned, definitely filled the rifle quicker than my Air Force and Benjamin pumps do. As one of the other members mentioned, the manual has pretty good pictures but the English instructions are a little weird due to the screwed up English, but it's not a big deal as the pump itself is very simple and easy to disassemble and work on. The included "rebuild kit" seems to have all the parts you'll need to rebuild it if you find it necessary.
I am really happy with this pump. For $72 bucks I think it's a heck of a deal :)
Jeff
-
thats great to hear its easier than the benji., that thing wiped me out when i had my mrod 25 cal one summer.
-
I was really impressed with how much faster this pump aired up my P-rod than my other 2 pumps. My other pumps work well but I really have to say I like this one much better :)
I can't honestly say how efficient the "air filter" on the pump is, but I like the fact that it has one and that is comes with all those extra filters too.
I'm really happy with this purchase :)

To make this even more attractive, eBay is running a flash sale with coupon code CFEBFLASH10OFF for $10 off $50 until 6 pm PST today only ;D.

The ebay price war is on, now $65.52 with free shipping. With $10 off it comes to $55.52. I am tempted to buy another one.

This is not the one that I bought, mine has the longer foot rests.
-
what 10 dollars offf?? i see it for 65 shipped .. no discounts listed.
-
WOW<all this means is that as we always knew, these are probably costing about 25 bux to make in china..for perspective though,thats a weeks paycheck for a factory worker in china.
-
with the " make offer" option i bet they will do 62 or 62 shipped LMBO

HOLY COW, THIS IS HILARIOUS.. people are still buying pumps for 200 and have no clue.. *(&^ i should buy 5 sell em on the yellow for 110 each
-
SOB, I need to block this thread before I end up with a spare for my other spare to the pump i use! :o :o
-
yep, at 55 its tempting to buy a few
-
these are probably costing about 25 bux to make in china
After some brief research, I found this pump in a chinese website for 30 bux. That means they are at least making 75% prifit since they can ship these in cargos which are fairly cheap. So they are making about 20 bucks a pump and lots of people are buying them.
-
makes sense/ retailing at 200 the airgun sites are killing it
-
Since the quick release on mine wasn't working, I ordered some BSPP parts but only to find out that they do not work.
If you are planning to replace the quick release adapter, it is a BSPT adapter, not a BSPP one. The tapered shape will not work with any Air Venturi quick release adapters.
I am ordering a $10 (including shipping) BSPT male to BSPP female adapter to make it work. So the $72 pump just became a $100 one factoring in the quick release adapter itself and the thread adapter.
I also found out why the quick release (foster) mechanism wasn't working. The placement of the ball bearings was all over the place, a few were too far back to fit the notch on the male adapter. Very sloppy work there >:(.
-
oh no.. seems like the foster female is the primary issue with these by all accounts.
-
Good thing all my males mates perfect with that female!
-
If they don't fit they are fairly easy to replace (I think)
-
If they don't fit they are fairly easy to replace (I think)
Yes and no. Yes, the quick release portion is easy to replace, Air Venturi markets some, and paint ball supplies have some, too. However, almost all American quick release adapters use BSPP threading. The pump, being Asian made, uses BSPT threading. So you will need an BSPT female end BSPP male end adapter to make use of all the quick release adapters.
-

Which adds more to the cost

is it cheaper to get an ebay hose with the connector?

Got this spare for the spare...best price on eBay. Don't know when I will eventually use it. Each pump got it's own o-rings and other stuff to rebuild it like 4X

The Chinese pump I am currently using connects with no leak and has positive lock up to my 2 HPA bottles, spare HPA regulator, QB78 PCP, maximus and varmint PCP.

The new hose arrived today and it fits the pump. The quick release also fits all the male adapters, but it was tight. Well, at least it worked. I just used the pump to charge my Guppy from 3500 PSI to 3600 PSI. That was a good work out, but the pump was not hard to pump even at 3500 PSI.
All in all, this is a good pump for the money. I just wish quality control is a little better, esp. with the quick release adapter!
-
thats really great to hear.. i thought the benji pumps were pretty taxing from 2500 up
-
thats really great to hear.. i thought the benji pumps were pretty taxing from 2500 up
As they say, YMMV! For reference, I am 5'5" and weigh 177lb, not exactly fit or active. My doctor said I am "borderline obese". I guess this means I can use HPA pumping as a form of exercise!
That said, I do have to put my entire weight on the handle and rely on momentum to get to the bottom of the stroke. 30 strokes and I need a short break at 3600 PSI!
-
i weigh about the same , think i had to drop my weight on the benji about 2800 ish.. I barely remember
-
I received mine today, was missing the spare oring set, contacted the seller about it.
Tried it out, gun was at about 2600, pumped it to 3000
Was not that bad actually. I am 5'10 and 178
Just using body weight by dropping knees to drop body straight down versus bending over it like how I normally pump my bike.
-
I bought one about a month ago and it hooked up to my Benjamin Maximus with no problem. I removed the handle and put a small piece of air filter foam over the intake port that is at the top of the tube, then screwed the handle back down on it. Figure this will keep dirt out of the tube.
-
Seller sent a reply but it appears they don't have spare oring sets available
They seem to get them as a complete package from the China factory with the extra oring set included.

Anyone tried making an offer for 65$ I am wondering how cheap theses will go. I really can't see why anyone would buy a Benjamin pump with these at half the price. I got one of the pumps from that woot deal awhile back but these are cheaper than that was.

they have the best offer open for a reason i guess. These pumps from what i gather are wayyyyyyy better than the benji and airfoce pumps.
-
I bought one of couple months ago and I think check valve is clogged up but I can't find where it is and no diagram came with it. Pump will go down and when I try to pull up it wants to not so good handle back down and won't build any pressure in rifle. Anyone got suggestions?

youtube "3 stage pcp pump"
there are a some vids from the manufacturers
you may need to pause the video as the guy goes rather quickly.
one thing in the vid i saw was that it appears to be filled with oil as he poured it out.

Not sure whether this (https://www.youtube.com/watch?v=p5Dm2NNXEng) is the right one, don't have enough time to watch the whole thing through. But it seems related.

internally im pretty sure theyre all very similar.. once you rebuild one , you can do them all

Do not order from echo_mall . They never sent my pump and the tracking info was never scanned by FedEx. They are stalling on the refund and want me to wait 3 weeks for the pump that was shipping from California. I had to escalate the issue with PayPal.
-
Been using mine a bunch, have never opened up one of these but it appears to have oil inside
since with regular use there is a fair bit of oil coming down the shaft from inside
the oil stays pretty clean and not turning a black mess, I guess as it is stainless steel.
Only once did it seem to have any moisture from the bleedout.
It is actually about the same or slightly easier than pumping my road bike tires to 110psi with a
joe blow sport stirrup pump

Just bought one from "digitalzoneproducts". Offer of $63.00 accepted. This included shipping. Came in a black plastic hard case with a spare set of o-rings. I contacted seller and asked about thread type, explaining that I needed to purchase an adapter for my gun & they quickly replied they would contact manufacturer but asked if I would accept compensation for me to "fix" locally. Can't ask for much more than that.
-
Wow, thats crazy.. good to hear
-
I never considered asking about threads after reading here before purchasing they were BSPP. And they are. So now I'm nut rolling decisions on the cheapest, easiest conversion. My separate purchase of a stainless BSPP (G) to NPT adapter was a wash, the BSP side was very poorly machined, no sealing no way.

I believe that one described is called the Tuxing compressor. There are a couple of listings on Aliexpress.

that one only costs 100 bucks in china. The shipping for each one is well below $100 bucks.

I mean the cost to make from the manufacturer directly is 100 bucks. Everything in Aliexpress has been bumped up. The shipping cost, if in bulk is well below $100 since it only takes 150 dollars to ship 1 cubic meter of goods without weight limitations.

oh, i had no clue you could buy direct.. pretty cool, ill have to google it

I'm going to buy a Benjamin discovery today - my first PCP. Will I need any special adapters to use the pump?

a few guys said the foster fits, others said no.. so u may need a female foster for the hose

best bet, go back into the thread and see what other guys did

yep.. the provided foster apparently fits chinese guns just fine, but doesnt fit the american foster nipple.. Another challenge might be thread connections , Im not sure, i just found the deals , dont have the handpump

The eBay hand pump I bought fit my marauder connector fine
It is brass though

I got a replacement hose and foster end fits okay, a little tight. Last night, I did a side by side comparison with a Hill mk4 as I hand pumped my Mutant shorty from 130 bars back up to 220 bars. The Hill was definitely smooth, but the cheap pump took less effort and pumps faster. We will see about the lo gevity in time.

The clones they've got out there are very inexpensive and work great now days.

My chinese pump has positive hook-up with Benjamin Maximus, Ninja HPA & Tippman HPA. No forcing and wobble when connecting plus no LEAK. I only go 3K max. for my applications.

This one said $65.37 AND $9.99 shipping or make offer. I don't have any intentions of hand pumping on a regular basis. But, if the price is right I wouldn't mind having one as a back up. So, I offered $55.37 plus shipping. I'm waiting for a response from the seller. It also said if the seller didn't respond in 48 hours that my offer would be null and void. What the heck.. nothing ventured nothing gained.

they might accept.. or counter offer a few dollars more. 65 shipped would be sweet

That's what I was thinking. Someone said they had to change the female foster fitting on the hose to fit all their guns... Heck I got some of those laying around.

I am one of the few unlucky ones with a foster end that did not work with all of my Air Venturi adapters. I took apart the foster end and found that the holes holding the ball bearings were drilled all over the place, some closer to the edge (not a problem) and some farther from the edge (that's the problem). Ordered a replacement hose and the foster end of that one works OK, still a little tight.
Random is the right word, but it is due to the lack of QC and somewhat sloppy workmanship. Some of the screws holding the folding legs to the main pump body were also drilled in a sloppy way. That said, for the price, it is still a good deal considering it pumps easier beyond 3000 PSI compared to a Hill Mk4.
Only time can tell us about the longevity of the pump. That ultimately determines whether the cheap pump is cost effective or not.
-
That was part of the consideration in my choice. The purpose as backup. It may never even get used more than the first time out of the box to determine that it does work. The purpose for that little donut tire in the trunk of your car is backup. Put it on and drive to the repair shop or the tire store. If I was going to buy a hand pump for everyday use I may want to spend the money for the quality. Providing it is, in fact, better quality and not just way overpriced like a lot of things these days. Yeah, I buy my shoes at Walmart. Don't really matter, shoes last me about 3 months no matter how much I pay for them.
-
from all accounts, its nicer pumping this imitation than it is a benji, airforce, and in some cases even the hill.. agreed on the shoes.. when I get new shoes that are expensive , wife wont let me wear them unlless were going out.. Because i destroy them in 3 months or less
-
Just bought a pump for $70.30...fingers crossed that it works with my disco.

Like Rob M said, it may fit or it may not. In my case it wouldn't fit any of my rifles so I just swapped it out with a replacement I had in my parts bin. Now it works just fine :)

No need to cross your fingers. ::) I now got 2 and works with my Benjamin Maximus, my spare hose when I checked works too. I read it's got issues with air venturi stuffs.

In my case, the $70 pump works better than the $200+ Hill mk4. The Hill is smoother with much better workmanship, but the cheap pump works more efficiently and easily at 3000+ PSI. I just polished the tip of the brass relief valve to fix a small leak (but only past 3500 PSI). Just hand pumped and got my Guppy tank from 3500 to 3750 PSI with the cheap pump!
YMMV, of course!

Try to make a 65 dollar offer if you want to save yourself half tin of pellet :P
-
the one I bought has 6 balls in the brass foster connect and they seem to be properly constructed.
I have seen an original benjamin pump which came with 4 balls and was very tight to go on.
my own is from a seller misjun2010
Only concern I have with these newer style pumps is there is no way to put a dessicant moisture filter
-
When making an offer to a Chinese seller, always use 8 as last digit. Offer $68 or $65.88 instead of $65. Most likely they will take it. 8 means prosperity to them.
-

You can. I assume you are referring to pumps with the inlet via the handles. Simply plug the hole in one handle and insert a piece of flexible tubing into the other handle. Run that tubing out to a small vessel filled with desiccant.

-
no, the intake hole is not in the handle but on the brass fitting at the top of the tube,
just where the screws that hold the handle down thread into.

-
Do I need to add a filter if I live in the desert? It's very dry here in Utah.
-
im pretty sure there is dessicant and filters in the top of the tube.. but it all depends which model i guess.IF theres not , u can always add a filtered setup.
-
I believe the type pump Lennyk is referring to is the style I purchased. The air intake port although centered between the two handle mounting screws in the brass cap, does not feed into the handlebar. Thus the port supplies air from under the handlebar, not through it.
The only way I see modding this is drilling/tapping the intake port and handle bar to accept an appropriate adapter. I suppose longer screws with sleeves could also be used, allowing space for a right angle adapter under the bar. Either way, the brass cap must be drilled and tapped. I think I would opt for drilling through both handle and cap, with a quick disconnect centered atop the handlebar, between the two handle screws.
-
Anyone know off hand if this pump has the right connection to fill an airforce spin lock tank?
I'm about to jump into the PCP world and this will be the pump....
-
does the spin lock have a standard foster fitting?
-
I'm having trouble connecting mine. :( I can only get to this point on my discovery.

-
step 1, take the ldc off! anyway , id personally lube and sand till it fit, but that just me since the nipples are 6 bux and a hose is 30
-
I don't really have to take the TKO off do I? Not worth it if I have to do that.
-
it looks like it clears the tko.. but as far as the foster, id read up on what others in the thread did
-
I may just send this thing back. I can get the Benjamin for $130 on Amazon and there is a $20 rebate. I'm not too pleased with this pump. The brass fittings are worrisome. Also when I opened the black case it came in, my pump was covered in water. Is that normal? The first few times I pumped it, water came out of the hose - this isn't normal right?
-
Yeah, that ain't good. Pretty sure I don't want to pump water into any of my guns. Really sorry for you but I hope it's an isolated occurrence. I've been on a pretty good streak of getting what I pay for. Hope all that don't come to a screeching halt. I do have a situation right now concerning the USPS but I'm not going to go into that until it runs it's course.
-
I've bought two of the clone pumps the first one was quite some time ago (long before this thread began) and it's a TAOUSA which was around $120 shipped, this pump came with two different female quick connects and the one that was already on it I had to change to the other one supplied. I've pretty much been using this pump exclusively and it has worked flawlessly on my Disco, Prod, Hipac'd 2240 and Mrod.
The last one that I bought was basically a no name pump (same basic G6 clone) and this one shipped direct from China, it came with an extra oring kit and a bunch of the filters (look like cig butt filters), this one too fits and fills all my Benjamin & Crosman guns and works great as well. I put this one back in the box after trying and am keeping it as a backup. This one was $80 to my door.
(http://i983.photobucket.com/albums/ae312/giant056/Airguns/Handpump.jpg)
Since buying my last pump I put together an SCBA tank setup and really love it, I only have to drive three miles to the dive shop where they fill it to 4.5K for $5. I also bought another SCBA tank which I'm going to cascade with the first to put unused air in from the other tank for the lower fills (2K) I still need one fitting to complete this one before using. Both of these tanks were completed for around $180 (tank, fill fittings and gage)

(http://i983.photobucket.com/albums/ae312/giant056/Airguns2/plumbing.jpg)
My very first hand pump was one that came with my Benjamin Discovery in the combo deal from Crosman. Since then it didn't take long after filling 3K guns and the pump literally gave out, they're really not a good pump for anything over a 2K fill and I doubt they'll last long.
-
Here is everything that came in the box: (https://s27.postimg.org/4352w2pjn/IMG_20170318_075606962.jpg)

I contacted the ebay seller and they have offered a $25 refund...so I'd only be out $45 if I choose to keep it. What would you do? Where can I get the fitting I need to attach it? What size do I need? Will any type of store locally carry this?
-
I'd take the $25 and search ebay for the right fitting. Or take your gun to Fastenal and fit it for a connector. I think I would go in and ask about it before you walk in packing a gun. Never know when you might run in to an over achieving store clerk.

Open up the fitting and you will see why it is not fitting. The holes for the ball bearings are most likely drilled all over the place. If they charge $25 for restocking, use that money to get a replacement hose assembly (which is a complete replacement) for $19 shipped. I would try to get a full refund first because if the description says it should fit foster quick release, it should!
This is an issue of QC, not the design itself. Now that I am using the replacement hose, the pump has been working fine for the most part. The only other issue was the relief valve leaking a little at pressures over 3200 PSI. I polished it and now it is working just fine up to 3500 PSI.
Regarding the Benjamin pump, I killed mine within weeks of pumping a .25 mrod. Opened it up to change the o-rings only to find that o-ring material got "burned in" onto the surfaces of the pistons/tubes. Even Hill pumps have their own problems. My Mk3 had the aluminum block (containing the check valve) fused to the brass body apparently due to oxidation and moisture/water collection.
At least with a $72 pump, even if the pump is completely destroyed, it is $72 and not $200+!

That's the exact same thing that happened to mine, ripples in the tubes where the orings gouged in.

yes, id buy a new hose with the 25 dollars.. or at least a new female foster off ebay from a paintball vendor

that is same pump as mine, I hope these newer generation pumps last longer than the older hill/benjamin types.
they are obviously of somewhat different design and all stainless too.
You got a good deal on scba tank setup for $180

This is so dumb. I just want to buy something that works that I don't have to tinker with. I am not the tinkering type. The only hoses I can find are shipped from China. I'm not willing to wait that long.

About the female foster, you have to be careful about the threading. I think the Chinese fittings use a different fitting than those used here. I am guessing the $72 pump hose uses BST as opposed to BSP threading.
-
I posted earlier today on the thread about "$70" eBay pumps which is I presume, the same type pump. My pump cost $70 or $72, don't recall. One thing I'm certain of, the hose threads are not tapered on mine. BSPP.
-
I had the same problem with the Chinese pump female QD fitting not seating all the way with the Air Venturi 1/8 female BSPP / male QD adapter for my Hatsan fill probe. I found that a 1/8" BSPP female QD fitting would not thread on to the Chinese pump hose fitting. I think the hose fitting is a metric thread which is not the same as 1/8 BSPP. I did find that it was the same thread as 1/8" NPT but it is not tapered. I fixed the problem by buying a 1/8" NPT female to QD fitting. The fitting wouldn't screw on the hose far enough to seal against the delrin insert because of the taper so I added a small o-ring behind the delrin insert and it sealed perfectly. This is the fitting that I bought (only used the female half): http://www.ebay.com/itm/PAINTBALL-GUN-HOSE-CO2-REMOTE-QUICK-DISCONNECT-1-8-NPT-STAINLESS-STEEL-SS-/282372409209?hash=item41beb50779:g:wj4AAOSwdGFYr-jT (http://www.ebay.com/itm/PAINTBALL-GUN-HOSE-CO2-REMOTE-QUICK-DISCONNECT-1-8-NPT-STAINLESS-STEEL-SS-/282372409209?hash=item41beb50779:g:wj4AAOSwdGFYr-jT)

I purchased the same ebay item Robert. I also locally purchased a 1/8 bspp to 1/8 npt adapter. I inserted the delrin seal from the $72 pump's brass qd into the adapter then threaded that onto the hose. The qd you and I purchased from eBay threaded onto the adapter . I had no problem threading the bspp on but the seal was definitely required to seat the adapter. I have no idea if the threads are metric or sae but they for sure are not tapered.
I havn't pressure tested yet as I need to modify the supplied plug for the new qd fitting or purchase a new one.
The eBay fitting you mentioned is a quality piece from what I can tell. It fits the Disco fill perfectly as well as another Parker and a Foster qd on hand. I had also considered doing what you did, in lieu of the additional bspp adapter. I asked in the other thread and now here too, does anyone know a supplier for the small white delrin insert seal used in these $72 pump hose fittings?

This is the fitting that I bought (only used the female half): http://www.ebay.com/itm/PAINTBALL-GUN-HOSE-CO2-REMOTE-QUICK-DISCONNECT-1-8-NPT-STAINLESS-STEEL-SS-/282372409209?hash=item41beb50779:g:wj4AAOSwdGFYr-jT (http://www.ebay.com/itm/PAINTBALL-GUN-HOSE-CO2-REMOTE-QUICK-DISCONNECT-1-8-NPT-STAINLESS-STEEL-SS-/282372409209?hash=item41beb50779:g:wj4AAOSwdGFYr-jT)
Thanks - I bought one just to test it out. Sorry guys I am super new to all of this stuff. Will I need anything else to make this work?

This pump looks pretty close the the air ventuir g6 that i spend a lot more on .

It's a clone

Quick update - the ebay seller agreed to refund me $50 and I get to keep it. So I got the pump for $20.
-
jeez, they really dont want returns I guess. Might as well get the hose sorted out and keep it now

Good deal.... I almost hope mine needs a new adaptor.... lol

I purchased the same ebay item Robert. I also locally purchased a 1/8 bspp to 1/8 npt adapter. I inserted the delrin seal from the $72 pump's brass qd into the adapter then threaded that onto the hose. The qd you and I purchased from eBay threaded onto the adapter . I had no problem threading the bspp on but the seal was definitely required to seat the adapter. I have no idea if the threads are metric or sae but they for sure are not tapered.
I havn't pressure tested yet as I need to modify the supplied plug for the new qd fitting or purchase a new one.
The eBay fitting you mentioned is a quality piece from what I can tell. It fits the Disco fill perfectly as well as another Parker and a Foster qd on hand. I had also considered doing what you did, in lieu of the additional bspp adapter. I asked in the other thread and now here too, does anyone know a supplier for the small white delrin insert seal used in these $72 pump hose fittings?
#8 o-ring should give you a seal. That's what i did when i replaced the micro gauge on my on off fitting that connects to my qb79 and an Ninja HPA bottle. The gauge has flat end and long enough to connect to on/off fitting also with a flat surface.

I had the same problem with the Chinese pump female QD fitting not seating all the way with the Air Venturi 1/8 female BSPP / male QD adapter for my Hatsan fill probe. I found that a 1/8" BSPP female QD fitting would not thread on to the Chinese pump hose fitting. I think the hose fitting is a metric thread which is not the same as 1/8 BSPP. I did find that it was the same thread as 1/8" NPT but it is not tapered. I fixed the problem by buying a 1/8" NPT female to QD fitting.

Just use the white washer from your faulty one or use a #08 o-ring or you can use Oatey Fastape > http://www.homedepot.com/p/1-2-in-x-260-in-PTFE-Thread-Seal-Tape-306212/203529858 (http://www.homedepot.com/p/1-2-in-x-260-in-PTFE-Thread-Seal-Tape-306212/203529858)
Similar to what Crosman use on air tight fittings, It's black ptfe tape.

Another coupla questions on the $72 pumps. Mine came with a bag of spare parts minus spare oil. Is silicone oil what I need and where should I apply it? Also, should these G6 clones be opened up and inspected prior to use?
-
This is so dumb. I just want to buy something that works that I don't have to tinker with. I am not the tinkering type. The only hoses I can find are shipped from China. I'm not willing to wait that long.
Personally for me the tinkering part is part of the fun, I understand where you're coming from though ;D

Use something like this ---> http://www.ebay.com/sch/i.html?_nkw= (http://www.ebay.com/sch/i.html?_nkw=)trident+silicone+grease
You may be able to find it locally if there is a dive shop near you. The container I bought was 1/4 oz. and sold for $5. There is plenty enough for rebuilding several pumps.
-
Thanks for the tip. After searching a little more I realized I would need grease, not oil. I have a tube, I believe it's labeled "Super Lube". Anyway, it's silicone based and I've used previously in co2/hpa rebuilds.
-
There was a post on super lube on a pcp pump rebuilt and it had and it went kaboom at the vent screw. I only use 100% silicone grease and oil on my pumps.
-
There are different “Super Lube” products. One has to be certain of the product number. You may want to check this site out ---> http://www.super-lube.com/silicone-lubricating-grease-with-syncolon-ptfe-ezp-53.html (http://www.super-lube.com/silicone-lubricating-grease-with-syncolon-ptfe-ezp-53.html)
-
Mike you're right about the Super Lube, I ended up researching that a long time ago, it was right after I bought a tube (wrong kind too) from Harbor Freight.
-
I got a tube of white lithium grease around here someplace. I'll have to check that out.
FedEx is supposed to deliver my $70 pump today.
-
I use white lithium grease on my garage door opener rail & hinges. I use to use the super lube on my co2 air guns but not on high pressure air rifles got it used now on my fishing reels...it works!!! no fear of kaboom. I now use Trident 100% silicone and 100% silicone shock oil #500 & #750, no petroleum distillates.
-
OOPPSS I lied.... My pump won't be here til tomorrow. I have several things being delivered over the new couple days and I got it confused with another delivery.
-
Bentong, are you saying don't use the Super Lube synthetic with Syncolon ® (PTFE) for hpa/pumps? What you show in the pic is what I have. Also, is white lithium grease a no-go too?
If that's the case I'll hunt down some 100 % silicone grease.
Thanks, Ric

Got the pump this morning. Opened the box and things looked great. The test plug was already in the female foster fitting. I made sure the o-ring was in place and screwed in the gauge. Pumped to 3000 psi. It pumped up and held. I bled it off and took it to show Betty Lou in her computer room. I pumped it to 2900 and it instantly bled back to zero. Betty Lou wasn't impressed. I checked to make sure bleed screw was seated. All looked good. I connected to the Marauder and began to pump. It pumped to 2500 psi and would not pump any more and leaked back off. I placed a request for return. I'm sure I can find the problem and fix it with the rebuild parts included but, if we continue to do this we will continue to get this level of quality. $70 is a good deal on this pump.... if it works out of the box.
-
I can see a drip of oil coming out under the bottom large brass nut at the base of the pump. It may need tightened or it might need a new seal... either way.. not working is not working. I did put a wrap of Teflon tape on the gauge because that's the only thing I had to put on the pump and I wanted to make sure I did everything right. Ebay sent an e-mail stating that if I didn't hear from the seller by 3/25 or couldn't come to terms I should let them know and they would get involved.
-
sounds like a minor problem im sure you will get sorted out.. they will probably offer to pay for your time..
-
Don't want to dig in until I hear what they have to say. The pump looks very good and did pump right up first time. I was feeling very satisfied with it.
-
true, dont void ur ability to return if thats what they decide.
-
The female foster fitting snaps right on the Marauder. I did not have that issue that others had. Some others said that their pump came with a plastic storage box. Mine did not.
-
pretty much a chinese crapshoot.. which for the price is fine.. the 100 dollars saved over the retail sites is well worth it
-
I am trying to fight the urge to buy a back up pump with a case that I can throw in my truck it is so tempting.
-
I have one of the better Chinese bull 2 pumps, and have had it apart twice already. My advice is get used to taking them apart, they can stop working for several easy to fix reasons...Even a buildup of junk will stop them cold.
-
Did you see the white washer seal when looking at the guage and bleed off port. O-rings, tiny black ball and white washer seals everything no need for teflon tape.
-

Yep, like I said.. the orings were there I just did the Teflon because I'm used to putting Teflon on threads, I have since taken it off with same results. Like I said, I'm pretty sure I can fix it. I just hate receiving something that don't work like it should. We tune our guns when we get them. Should we tune our back up pumps too?
-
I mean... the manufacturing cost is 20 bucks, what can you expect?
-

Really, it ain't that big of deal. I just want to see how they want to handle it before I dig in and find something cracked that I can't fix.

I brought one about 2 months ago as a backup for my Hill Pump, don,t figure I,ll ever need it as a backup so I hooking it up to a gearbox motor and have a electric pump..
-
good call, gear it heavy and slow , it will likely last a long time.

I watched a youtube of one before.

What gearbox are you using ?
I wanna build one too.

some people suggested this earlier in the thread, im not sure the threads are the same though.. The foster you do have is right, they just seem to come defective in craftmanship
-
I just had a revelation on the Chinese pump hose threads. I read the description of my pump more closely and it states that the hose output thread is M10x1 and the QD is 8mm. I measured the thread of the male hose end and sure enough, it is M10x1. This means that neither the 1/8 BSPP nor the 1/8 NPT quick disconnects are correct for this application. I was, however, able to get the 1/8 NPT QD to thread most of the way on to it and it is working for me. Also, I have not been able to find a M10x1 female to either 1/8 BSPP or 1/8 NPT male adapter so as to be able to use one of the above mentioned QD's correctly. Mystery solved for me at least.
-
well , 1/8npt will force thread into alot of threads, and actually create a good seal.. I know the safety police will hate this but its true
-
so this means it will be difficult to change the quick connect to another brand/quality ?
might be one use if the threads get mangled.
-
The 1/8 NPT QD threaded on my m10x1 hose easily and did not mangle the threads on either connector.
-
Oops! Double posted.
-
The 1/8 NPT QD threaded on my m10x1 hose easily and did not mangle the threads on either connector.
yep, 1 is 27tpi , other is 25.4 tpi, so probably meshed just fine.
-
those are mostly 24v ,, so running it off 12 v battery is no issue, just half rpm/
..Not enough power with the wheelchair motor, so I,ll stay with my Hill pump powered by a double action air cylinder..

Well. we played e-mail tag for a couple days. First they wanted me to take a video of the issue so their techs could deduce the issue. I told them that my explanation of the issue should be sufficient. You pump it and it leaks back off. I told him that I was pretty sure I could find the problem and repair it with the orings that they included. However, if the issue was more than that I wanted them to know so the they were aware of it before I "tinkered". They gave me permission to "tinker". So I "tinkered". I replaced the white oring in the bleed screw with one they supplied and it fixed the problem. I still have to find where that drip of oil came from and if it is going to continue dripping. I topped off my 2240 hpa conversion that has the 2260 tube from 1200 to 1900 in about 10 to 15 strokes. I forgot to count. It held great. I reported my results to them and they rewarded me with a refund..... 8%.... $5.62. Hey, it's a tin of winnies.
-
haha nice.. have you tried another higher pressure gun yet like 2900 psi
-
Not yet, that is on today's agenda.
I'll tell you what I do have... I nice little to go bag with a pair of 2240 HPA 16" barrel .177 carbines and a hand pump. All wrapped in a soft tactical carry case.
-
If the oil you are seeing is at the bottom bumper o-ring it's just accumulation of the lube from the outer tube. Every other pump i rub a thin dab of silicone grease and wipe the accumulated one at the bottom.
-
That's exactly where it was. A small droplet or two slowly drizzled down onto the black lower frame from just under that bumper o-ring. I wiped it off and it has yet to show again.

I am totally new to this whole PCP world having had a Sheridan Blue Streak for years as a teenager. I have just purchased an M10 and have a MaxAir MkII on order.
I have been reading quite a bit about hand pumps, condensation, desiccant etc. Everyone seems to have a different take on their setup and what really works and what doesn't. I'm spending more and more $$$ trying to come up with a home-brew desiccant "AirDryer" that is going to actually dry the air enough to overcome the inevitable condensation from compression. In all my reading the small desiccant intake "Moisture Filters" that are available should not be removing enough water from the air to make any meaningful difference.
Bottom line - who is having condensation issues with their hand pumps and their air rifle-pistol? or is this whole condensation thing a non-issue?
If it is an issue, what have PCP shooters using Hand Pumps done to really-finally overcome this problem?
Thanks
-
Drew, I am down on the Gulf coast. So I am very familiar with humid air. I do have a hand pump with a canister <--- (purchased from Harbor Freight or Home Depot or someplace) - but I just want to say it was cheap. So what I do to help get dryer air into my rifle is to refill inside the house and upstairs. It is always warmer and dryer up there.
Good luck with your new setup and have fun!

I never had any really bad moisture problems here in Michigan, during the really humid weather I always pumped inside of the house with the ac going. I've since taken most everything that I've pumped up apart without noticing any moisture damage but with years of use without disassembly I'd imagine a person could get some bad damage. Now I'm using tanks that I get filled at a local dive shop so I don't even have to worry about it, probably the only time that I'll use a pump anymore will be when I'm out hunting but that too is doubtful because I seldom go enough shots to require a fill again.
-
I've been using my hand pump for a couple of months now and have yet to see a single drop of water or oil come out of the bleed screw. Also, my pump came with a hpa filter that uses dense cotton cylindrical media and the only contamination so far is maybe one drop of oil. Most of the guys with elaborate moisture removal setups are filling tanks to 4500 psi with compressors, whereas we are only pumping by hand to 3000 psi or less. There should be less condensation at the lower heat and pressure.
-
Actually, condensation occurs when the pressure or temperature drops.
-
While lower temperature air will hold less moisture, lower pressure air holds more.
-
Have you seen the pictures of clouds forming above a high performance aircrafts wings when pulling Hi G manuveres?

Adiabatic cooling does that just like the link says.
Ever see condensation come out of compressor? Even shop compressors squeeze considerable amounts of water out of air.
-
I may just send this thing back. I can get the Benjamin for $130 on Amazon and there is a $20 rebate. I'm not too pleased with this pump. The brass fittings are worrisome. Also when I opened the black case it came in, my pump was covered in water. Is that normal? The first few times I pumped it, water came out of the hose - this isn't normal right?
i got my pump a few days ago and just tried it today and mine was full of water also,literally sprayed out when i tried to pump it.
good thing it wasnt hooked to a gun.
-
well, i guess using water as a coolant is fine ,but the pump should come empty becasue obviously it leaks
-
After some brief reading on the manufacturer's website, the pump is supposed to be water cooled. But looks like some of them leaked during transport and storage.
-
Wonder if it matters if the bleed screw is opened or closed during shipping.
Mine was closed and no leaking of water.
-
I store mine with 2 pumps, reads around 500psi.
-
Wonder if it matters if the bleed screw is opened or closed during shipping.
Mine was closed and no leaking of water.
my bleed screw was rolling around inside the case it came in. so i tore it apart and am going to rebuild it and see if it holds. dont look too hard to do
-
tore mine down and replaced an oring that looked chewed up,
i used the little plug for the hose to see if its building pressure until my gun gets here,
and............. its hit and miss.
sometimes it will pump up and hold just fine,and sometimes it wont,
but whether it builds pressure or not there is still water coming out of the hose when i pump,and the bleed screw when i bleed the pressure.
what did i do wrong?
and can i use it without the water inside?
arrrghhhhh i need to figure it out before my gun arrives.
-
Chris, I am fairly certain you want to shoot an air gun and not a water pistol. DON’T put any water in your air rifles/pistols.
-
haha roger that
this pump is making me REALLY miss my joe b great white :(
if i can run it without the water inside to cool it,and just pump slower so it doesn't heat up then thats what ill do.
-
So I have an EBay pump as well. So far so good. Appears to be no desiccant, air is sucked in under the handle.
Thinking about tapping for a 1/8th nipple/couple to extend into the handle. Seal it up real good and then boost it the same way I have seen the Air Venturi pump boosted, adding the harbor freight moisture filter...... hmmm
When I first received he pump, it had silicone oil in it. The instructions said to pump it so many times before use.......
-
Oh No !!! They came with instruction?
-
Back when I bought my last pump it came from China, I just checked where I got it on Ebay going the route through paypal which I used to pay for it. Its gone down in price a little since I bought mine. The pump tubes are 304 stainless, I just check mine with a magnet to make sure and a magnet don't stick.

50 bucks ya sure can't beat that with a stick, it's the exact same thing I paid 64.95 for a couple months ago, they're a great pump too, being they're made
from stainless, they'll last indefinitely just about, all you need to do is once in a great while replace orings when they wear out, sure don't have to worry
about rust at all, there's nothing to rust on them.
-
At $50 there is no reason everyone can't have 1..... or 2. I see a run of home made compressors on the rise.
Wait... wait... I'm getting a vision...... a double pumper..
-
Yeah, gonna get another one and try rigging the wheelchair motor on 24v with low rpm pulley system
Somebody on youtube has done so.
-
Yeah..... a 2 speed washing machine motor on low speed with a small pulley running a big ole wheel with a pump on either side tee'd into one reservoir. Check valve each line so they don't fight each other...... oh geez.
-
Hi Bill,
did you run the wheelchair motor on 12v or 24v ?
Also with no further rpm reduction ?
I am gonna attempt to build one with some further rpm reduction and run it at 24v with a pair of 12v Dell power supplies in series.
those are mostly 24v ,, so running it off 12 v battery is no issue, just half rpm/
..Not enough power with the wheelchair motor, so I,ll stay with my Hill pump powered by a double action air cylinder..

Umm... I think you got me confused with someone else... I just think this crazy stuff up I don't actually do it.

If I buy a back up for the back up's back up...I might end up buying another PCP to pump..learned my lesson on the walmart/amazon UTG clone scopes, ended up buying another pcp to mount it on so it don't go to sitting lonely.

Hi Bill,
did you run the wheelchair motor on 12v or 24v ?
Also with no further rpm reduction ?
I am gonna attempt to build one with some further rpm reduction and run it at 24v with a pair of 12v Dell power supplies in series.
those are mostly 24v ,, so running it off 12 v battery is no issue, just half rpm/
..Not enough power with the wheelchair motor, so I,ll stay with my Hill pump powered by a double action air cylinder..
12 volt

Do you think a firecracker could produce enough energy to detonate tannerite if you sealed it up real good inside the jar?

I had tried one of those cheep Chinese pumps and they are garbage. They use knock off Foster fittings that won't work with the real Fosters. After giving them a bad write up on eBay they gave me a refund for updating it . I just added to my complaint that they did satisfy me by giving me a refund they also let me keep the piece of junk. I can't even get it to blow or a balloon.

BILL, i dont think they will fight each other since the pickup is not tied into the high pressure end.. a basic manifold with 2 inlets and 1 output ( as seen on youtube ) would do the trick. pretty cheap too :D
-
Probably right. I was thinking if one was on the upstroke as the other was on the down stroke.. but it don't matter. You and I both know I ain't gonna build nothing of the sort anyhow. That's $100 towards a Chinese compressor... Heck, a few more weeks and those will be $200.

The above link is from Rob M on 3-30-2017.
I bought a pump that looks just like this one for $72 and it works better than my Benjamin.
I am tempted to buy another one for $49.99.
$49.99 is a BARGAIN for a good pump!!!
-
I'm really surprised that Crosman is even still selling their pumps, people in general that buy them must not be aware of how bad the pumps really are.
When I bought the pump that Earl is talking about for $49.99 I paid 64.99 plus $15 shipping and that was direct from China, it's truly a stainless
pump which makes it rust free, really the only thing to wear out on them is the o rings. If you use good silicone oil in them they'll probably last a
really long time. Mine came with an extra set of o rings to boot. I posted a picture of it probably ten pages or more back in this thread. Now there's even
a video on youtube putting water in one to cool but I wouldn't ever try that because it's an accident waiting to happen, I've already seen a guy who
posted how water shot out of his pump when he got it. Supposedly the Chinese guy uses the pump with water in it though. ???
-
You had yours apart?
-
No but magnets don't stick to it at all, except on the screws that hold it together.
-
I would almost bet it has water in it too.
-
I would almost bet it has water in it too.
Holy cow Bill I honestly thought you were feeding me BS , sorry about the crappy thought but you are right, the darned thing has water in it, this makes me wonder if this thing is even safe to use.
-
LOL.... they all have water in them... it's there to help them remain cool.
-
seems to me , you get a pump for 49.99 shipped you pretty much plan on a reseal right off the bat , and a basic quality control inspection.What we need in this thread is a " out the box " tutorial on what kinda issues there might be ..
-
Mine came with some oil inside, instructions to pump it a few dozen times before use.
Works great. The gauge is suspect. Other than that, it's a win.
Honestly, anyone who thinks the other more expensive pumps aren't made in china are kidding themselves.
I'm fine not paying an extra $150 for some stickers
-
I just ordered another at the $50
My original $72 has been used a lot over the last few weeks, no water has ever leaked out.
A fair bit of oil was on the exposed first inner sliding surface, enough to drip past the exposed oring and onto the feet.
I wiped that off but some more oil has collected with all the usage, not enough to drip out but a fair amount on the oring there.
Not sure if oil is stored in between one of the chambers like how I assume the water is.
-
I ordered one of these when they offered free shipping 3 days ago. $50 for a HPA pump delivered is a smoking deal if it works...

well, it works fine!! pump delivered today, I didn't expect it in two freaking days :o Nicely boxed and padded. Only thing I had to install was the pressure gauge. Good amount of lube on it but not dripping silicone. NO, ZERO water in the second stage ;D After checking it over real good and reading the directions(funny stuff!) adding water is not mentioned the engrish manual.
I put in the included pressure check fitting and took it up to 3500psi in about 7 pumps, not bad! bleeding off the pressure showed no signs of water, lube or moisture.
The fill whip is fairly nice but time will tell how good it is... the female foster fitting snaps right on every male fitting I have, mostly Benjamin with a Hipac and a couple Chinese AG's in the mix. The Blue thingie between the foster fitting and hose has a little fiber filter in it, nice touch! The fitting are brass, not sure how I feel about taking brass up to 4500PSI.... Thankfully, none of my guns even need a 3000PSI fill.
I pumped up my Prod from 1800 to 2600PSI in 35 strokes. This pump is easier than the benjie by a small margin. The gauge on the pump and the one on the gun were within 50-75psi... keep in mind I'm not positive either is correct.
Also included were what looks like a full Oring kit,6 8 of the little fiber filters and a cheap wrench as well.
Overall, I'm pleased with the purchase. I'm kinda thinking I should have ordered TWO :(

How did you verify it had no water inside ?
Did you dismantle ?

Yep, I'm known for taking something out of the box and tearing it apart just because I can :D
forgot to add. I've got about a dozen fills off the pump so far, No issues yet.
I did make one small mod. Since the air intake is between the handle and top of the tube and can't easily be modified to accept a descant cartridge. I folded up a piece of filter mesh and sandwiched in between the handle and tube port. Might help keep a little dust out of the pump...

Little update on my pump.
Yesterday was a ruff day for my arms and shoulders... I shot several guns through out the day, LOTS of pumping :D
No issues at all with the cheap ebay pump. last night, I tore the pump down to inspect and lube a bit.
All the O-rings look new, no tears or noticeable ware. The sliding surfaces all look smooth and shiny, no burs or odd ware patterns.
I used silicone grease and oil to lube it and just reassembled, no need to replace anything. With fresh lube, the pump does seem a bit smoother, still works fine.
I had no heat issues and my pump has NO water in it. I only pump 35-75 strokes at a time. The tube gets just warm to the touch, I didn't shoot a temp reading but I'd guess 90-100 degrees after about 75 strokes. I normally pump 50 or less strokes so heat build up is not a problem nor is the lack of water in the second stage(not that this pump ever had water in it)
I'm very pleased with this $50 pump ;D
-
yeah, 50-60 gets it just warm and good time for a break anyways
-
I never pump more than 30 consecutive times. I break for 15min. before I use it again, but I rarely get to pump the Disco's that much, unless I am filling both of them back to back. One of these days I will use the pump on one of the Condors just to see how many pumps it takes to get the 500cc tank close to 3K psi, but I am not looking forward to it :) And more importantly, I don't want to break the pump...
-
yeah, 50-60 gets it just warm and good time for a break anyways
Yep, easier on the pump and more importantly ME!!!
My normal fill with a hand pump is 25-40 pumps before stopping. Since I'm doing most of my shooting at home, I can keep the fill small and more frequent. I just did a couple of 75 stroke fills just to see how the pump handled a little more than normal use as far as heat build up is concerned. I'm pushing 50 years old, these "tests" won't be happening again ;)

I've thought of motorizing using one of these budget pumps and have been looking for a "donor" but haven't thought about a drill press. Says its 1/2 hp. Wonder what size motor is needed...I may need something bigger, since I'd like to have a twin pump setup.

Converted a couple 2240s to HPA with 2260 tubes (valves pinned). I only use the pump for those guys and save my tanks for the MRod and FD-PCP.

its like it only works sometimes.
and to top it off,my maximus came in today and of course the pump is choosing not to work at all today >:( >:(
i really dont understand why,
ive had it apart 30 times,
each time i put it back together and plug the hose with the included plug and pump,
sometimes it pumps up to pressurize the hose and sometimes it just does nothing.
im about to chuck it off a cliff,if i could afford another tank right now id sooooo get one.
(note to self,NEVER EVER again sell your joe b tank,its worth more than its weight in gold!

A conveyor belt motor with a reduction gearbox would work good.
-
yep, the only issue with the gearbox reductions is generally the price.. IF you scour ebay , they can be had for cheap with the right input shaft for whatever 120 motor you happen to have.. really , for the right speed to pump the motor , you need really low rpm , Id go for one of the 40:1 reductions ..EVEN then with a 3000 rpm motor , you are turning 75 strokes /min , still to fast for the pump .. So 50 to 1 or higher

heres a 60 :1 which would be 50 strokes per min on a 3000 rpm motor , about right , still a bit fast.

its rated for .23 hp , id bet it would be perfectly fine running 1/2 hp which would also be sufficient to do the work ( reason I say that is workload, most of these are designed for sustained work over 24 hrs in a plant, not pumping a gun for 12 mins)
-
Might not hurt to check with the local scrap guys , either they may have or keep an eye out for an item with reduction , and or pullies and belts to achieve the desired reduction , I did this making a drumal stye compost sifter/tumbler, using 2 aluminum motorcycle rims as the drum form spanned with 1x2" spacers to fasten hardware cloth <~ little off topic lol , reducing a 1200 ish RPM motor to 33 1/3 rpm. any faster the compost was acting like it was on the grav-a-tron ride at the county fair ???
-
Yeah, I think it would likely have to be done with scrounged cheap/free parts or the costs will add up quick! You would soon be near the price of those small Chinese compressors that keep tempting me. On the other hand, I would love the simplicity and ease of maintenance/rebuilds with a motorized hand pump setup.

well, u need a matching motor shaft for the input , and whatever the reduction ( lets say its 10-1 ) you just need to do a pulley reduction on the output to drive the pump ( in this case 5-1 pulley reduction giving 50:1
for free, you cannot beat that
-
yes, I think a final stage pulley would be the easiest way to fine tune the final rpm

Sounds like either the bleed valve is not sealing all the time or the check ball in the top of the tube/check valve at the bottom isn't sealing all the time.
Do you hear air coming out of the top of the pump on the down stroke? you should only hear air being sucked in as you pull the pump back up.... Check ball might be sticking or just not sealing every time.
Same with the bleed valve, when closed and sealed, you should hear no air coming from it. maybe put a little soapy water around it and see if it blows bubbles as you try to pump.
The lower check valve, I'm not sure you can tell if it's working by sound...If it's not closing at full down stroke, the air you just pushed in the hose will be sucked out on the up stroke... you'll never build pressure.
-
Hi guys,
I'm late to the cheap-pump party, but thought I would report my experience, especially for the people who are having problems. I completely disassembled the pump before it came near a gun, since it would not hold air at all out of the box.
I found significant machining swarf (brass) in the threaded areas, and water in not just the jacket, but also the inner compression chamber. In addition, I found the fill hose, as well as the bleeder, gauge, and fill quick connect, use hard plastic bushings as a sealing mechanism, and they were the major part of the sealing problem (probably not any news to you all who have bought before me). I sanded/polished the white bushes flat with 2000 grit, coated them with light silicone, and torqued them a little snugger. Finally I knocked the burrs off the brass fittings and tube ends where possible, to try to make the o-rings' lives easier on reassembly.
Anyway, with the test plug it has now held at 4500 for 4 hours, so I'm happy.
Before using the pump for real, I'm going to mill up a press-fit adapter for a male 1/4 npt air compressor fitting to go on over the intake, so I can hook up my desiccant pack and maybe then boost it a bit. I have had great luck boosting my old Hill MK3 while topping off a field tank and don't see any reason not to boost this as well. If anyone has done this already, I'd love to hear some details or see pictures!

Here is one way of getting a threaded connector onto the input port of these cheap pumps...just a 20mm spacer, with o-ring facing down, clamped between the brass inlet fitting and handle. New screws needed - M5x0.8x50mm. No mods to the pump parts at all. It works great to hook up a large desiccant and also boost by 14psi.
-
nice work, but what seals the handle?? looks like a complete pass through
-

No need to seal the handle at all - the center hole only goes halfway into the spacer, and leads only to the 1/4NPT female threads. That hole and o-ring shown in the middle photo touch the brass part of the pump. There's no center hole on the top side.
-
Brilliant !

gotcha, awesome!

Great work there cowtown.

Just received my china pump but I have read somewhere there is a sort of break in and maintainance you must do before use is this true? I know it is cheap pump but I would like it to last as long as possible.
-
How do you like it?
Just ordered one (the 2nd one) to keep as a backup pump. For that price figured "what the heck" :)

I just took mine apart today and cleaned it up. I can confirm that there is water in the inner-most aluminum tube. However, that water is not going anywhere if the pump is assembled correctly. In other words, that water is only for cooling the pump and does not get into the the air path. I did notice significant corrosion of the aluminum, but not to the point that the material is weakened. When I reassembled, I used coolant instead of water. Also, the amount that I poured out was very little, not enough to make a big difference. After putting more coolant in, the pump definitely radiates heat more efficiently.
Mine needed to be torqued down to the base quite a bit to stop leak between the base brass nut and the base itself. After torquing it down, I can now pump to 250 bars quite easily!
I have to say the pump is actually well designed despite quality control and workmanship issues. Do watch the videos on Youtube to learn how to disassemble the pump, it is surprisingly simple. Except for the base brass nut mentioned earlier, everything can be just hand-tightened in my case.
If your pump is working, with proper maintenance, it will probably keep working for a long time.
-
Something weird...
I have 2 2240/2260 based HPA carbines. They both use 2260 tube and Disco fill adaptors. (yes, valves are pinned). The hose from my Chinese hand pump snaps right on one of them and pumps it like they grew up together. The other one? No joy at all.
-
Compare the fill nipple tip, are they of same length? I noticed that some male foster tips are longer than other. Just had to file it to fit.
-
Think I'm gonna take the pump to Fastenal or someplace and buy a handful of fittings.
-
Does anyone know if a hose from a hatsan pump can be installed in this pump ?
Friend wants to get one and has a damaged pump with good hose, probe.
-
feel i should update my post about this pump thats been driving me crazy lol
i found the culprit not long after i posted that i couldnt figure it out.
the smallest oring on the innermost small rod (that goes on the brass piece with the black plastic spacers) wasnt sealing,
the extras that came with the pump wouldnt seal either,
replaced it with one of the same size but better material that i had in my oring box and its been working great ever since to fill my maximus.

Does anyone know if a hose from a hatsan pump can be installed in this pump ?
Friend wants to get one and has a damaged pump with good hose, probe.
The Hatsan pump hose will fit , the fill adapter may even work one the new pump.

Thought I'd chime in
I've had my pump for about 6months now. Works great.
Recently I got a new valve for my AirForce gun that included a new foster fill port.
I went to fill up the tank and the hose did not fit the new foster connection. At first I suspected the new connection. But long story short, it was the female QD's on the hose. Despite both being "1/8th" only one end fit the connection to the pump, and the end that fit my original AirForce valve... well upon closer examination it had been slowly chewing up the male foster port. When I looked closely I could see that the small bearings in the female QDs were not all lined up the same either.
So, I ordered an Air Venturi female QD to replace the one on the gun side of the hose. It fits everything flawlessly.......except the hose itself which has different threads......grrrrrr
So, no I ordered a new hose that should be here next week. And between the Air Venturi QD and the new hose I've basically spent enough for a second pump......
For reference this is the one I have: https://www.ebay.com/itm/282446221458 (https://www.ebay.com/itm/282446221458)
So maybe be aware that not all Chinese 1/8th fosters are the same...... Other than that, no complaints at all!
