The wonderful "China pump"

[Balu]

I have 3 still brand new in boxes

You're all set to make this Homemade PCP pump compressor.....

honestly after looking up the motor used.. this is fairly easy to make at about 70-80 bucks give or take.. i'm now looking into making a stand lol

I'm confused by the motor. I have some extra steppers laying around for replacements on the CNC. Would those work?

There is also this one.....(as you see I'm looking at options for a homemade compressor if worst comes to it)

I wonder if that same motor would work with a 4-stage pump to make 4500 PSI?

Good question. Some airless sprayers develop/use high pressure. The old Wagner Paint Crew system in the shed shows a PSI of 2800 (193 Bars) with a 3/8HP motor. There should be a way to use that compressor and pump system to make that system into a working PCP filler.

how big of a cnc, we talking home made so small steppers like for 3d printing or larger?

Should, its nearly the same force as a 3 stage when it comes to that.

Some leverage devices in action:





I think with either of these a 4-stage pump could easily be used for 5500 PSI.

http://zypcppump.com/what-different-between-3-stage-and-4-stage-hand-pcp-pump/

Zhongyan 3 stage up to 4500psi is special design for airgun cylinder,  stainless steel construction, cooled liquid filled can keep the hand pump in low temperature and the liquid will not be frozen even -20℃.

There is a better pump than 3 stage hand pump, that is 4 stage pump. The biggest different between 3 stage and 4 stage is the CONSTRUCTION. The 3 stage pump included total three tubes, but four tube the 4 stage have. It can makes the 4 stage pump up to 5000 or 5500 psi, and that will be more easy to fill a cylinder.

Usually, the max pressure of airgun cylinder can be held is 4500psi, but as a professional pcp pump manufacturer, we suggest 3000psi filled is enough for airgun cylinder. 4500psi is a very high pressure, if you fill 4500psi to cylinder every time, the lifetime of pcp pump will be shorten.

Zy PC Pump.com website has been down for about a week. It looks like they didn't re-register their domain name.

(Zy PC Pump is the maker of the chinese hand pump we commonly see)

I hope they do come back.

Wouldn't that turn my airgun into a paintball gun?

$%&&*. I made it to this thread WAY TOO LATE.

Paid $213 for an AirForce pump. Wish I'd seen this.

The Mophorn was back on Amazon for a couple weeks at 66 bucks, I'm waiting for them to be on Prime because shipping is a Killer to the Islands.

[Nomadic Pirate]

I bough a bunch of guns lately so I've been doing a lot of shooting,

I can't praise enough this Great China pump, it just keeps going with zero problems, zero signs of any pitting on metals ( My many HILLs by now would all have plenty pitting )

I did end up buying this :



cheap enough for extra insurance and can be moved from pump to pump in a second.


Waiting for the Mophorn to come back up in the 50 bucks range and Prime to get me one,
....and still keeping my 3 TOUSA in boxes, I open them up few weeks back and did a little silicone rub on them and re-boxed the up

Can you boost them with a shop compressor?

Concur 100%.

I did- however- just get a compressor.  Tendonitis + arthtritis got severe enough in my left elbow I had to get acupuncture.  Can't even do push-ups or dips now, and handpumping past 205 Bar is a no-go (that's the most I can do with my Toausa 1-handed).  Next time I see the hand-pumps on Prime drop below $50 I'll get a spare.

Speaking of "China pumps", I just watched a Youtuber named Afro Sniper X, say that the Hatsan 3 stage pump is much easier to pump than a Chinese.  Any truth to that?  I'd send more for an easier to work pump if so....

My first pump was a Hatsan. Very heavy, hard to pump, very clunky, would rust very quickly. This was a one stage pump.

The new Hatsan 3-stage looks just like a chinese pump. Same as the Diana pump, the Webley pump or the Air Venturi pump. All just rebranded chinese pumps imo.

[JnJHess]

I agree Ron. If you look closely at all this pumps you listed, you can only say they look all very much alike.

[Nomadic Pirate]

I remember those old Hatsan pumps I had 2 of them ......Heaaavy and yes they would rust very, very quickly.

I think you are right, same derivation and re-branded with all kinds of names

[larspawn]

Out of curiosity I looked and it doesn't seem like they are "cheap" anymore.  Seems like all over $100?

[JnJHess]

Yeah if you look at Amazon, the trend for the cheap China pumps is slowly faiding away, and is more heading towards $60,70, 80 and 100. Even that has come to an end. I have bought one as backup about 4 months ago for about $48 around and that one was hard to find.
