BETTER PICS ON POST 7. These are gouges in the metal. The pics are rough but you get the idea. Has anybody else had this happen?

contact sun optics and attach those pictures, they should send you a new pump if its still in warranty.. you said its new so id think something like that would be a replacement pump

if you got it from pyramydair.com, maybe try giving them a call and sending them the pictures. if they offer to replace it for you ask if they would be willing to take the cost of a new benji pump off the price of the hill mk 3 pump and you pay the difference. its a long shot but if they go for it shelling out the extra cash if you can would be well worth it in the long run.

I got it from airgundepot. I am going to contact sun optics tomorrow.

MustangMike · « **Reply #3 on:** May 21, 2012, 12:21:40 AM »

contact and ask airgun depo tomorrow about replacing it and putting the cost of a new towards a hill mk3 if you can swing it. the repair kits for the hills are sold at pa, their easy to find and are deff well worth the upgrade.. if airgun depo says no then contact sun optics ir if agd offer to just send you another benji up.. choice is urs

Thats weird how it got torn up so soon,.. Or even shipped loking like crappola. I have a benji pump, its a PITA man, i have to tear it down and replace seals every few months. If i could go back and do it again, id probably just buy the hill pump. The benji pump "works" but thats about all i can say good about it. Tearing it down gets old pretty quick. It will keep you strong and keep you shooting but i cant say its very reliable.

+1 on the pushing for a hill pump like the other guys say.

my pump is getting a ruff spot on near the top of the up stroke, feel slike a 1/4 - 1/2 inch area of very slight metal on metal. im going to need to figure out what to do soon, i dont see buy maybe 2 3000psi fill guns in my distant future. the rest will be based off the disco platform so that means low fill pressure with a 2500 psi fill max on the power hogs.

im pretty decent at wet sanding and polishing stuff so one day so when i go to do a rebuild i might try and smooth some stuff out and polish a little here and there.

How many "fills" on that pump?
My Benji pump has 6-7 fills (180 cc 0-3000 psi) or about 800 strokes on ot, I'd consider it still new - 2 months old anyhow. It's still working well and is quite smooth. Yours shouldn't look like that it is a lemon for sure. BTW, before I put any air through mine I added an in line air dryer, I see yours doesn't have one.... Sun Optics does offer a kit and the Hill Pump also has a dryer kit. Every hand pump should be fitted with an air dryer and keep it replenished. If you don't want to buy the "kit", you can get air dryers for air tools cheap at Home Depot, etc... and with a few 1/4"-1/8" NPT brass adapters you will be pumping dry air in short order.

I received the pump on March 22nd so mine is almost 2 months old. I have contactd Sun optics and we will see what they have to say. I have about 25 fills on it. Here are better pics. All of the marks on the pump tube are gouges.

dukemeister · « **Reply #8 on:** May 21, 2012, 02:55:40 PM »

Refund! That's just narsty, looks like a processing deficiency during manufacture to me.

QVTom · « **Reply #9 on:** May 21, 2012, 04:09:55 PM »

A plating failure for sure. Are they chromed or Nickeled ?

That's a QC issue. Should have never made it out of the plant. Coating failure is what I say also.

bradyman1 · « **Reply #11 on:** May 21, 2012, 08:39:23 PM »

Sun optics told me I can send it in and they will rebuild it free. I asked for a shipping ticket, we will see if they will offer to pay for it.

I hope they pay for the shipping. That thing looks horrible. I've had my Benji Pump for about 8 to 9 months and I use it all the time and it has a little marking on the main tube, but nothing like what has happened to yours. I hope they make it right for you.

bradyman1 · « **Reply #13 on:** May 24, 2012, 11:12:32 PM »

Sun optics told me a couple days ago that they were going to send the shipping ticket. I have not got it yet but I will keep you guys up to date.

That looks terrible! Looks like they forgot to lube it!! I had an airforce pump that was bought used which is the same thing for over a year and only had to rebuild it once. It did work well while I had it. Sun Optics was more than willing to work with me on getting a rebuild kit out to me, Free! Meanwhile, I bought a Axsor pump, and it was much worse than the airforce pump. It only lasted a week before it became stuck on the down stroke and refused to go down. After that mess and returning the Axsor, I bought a Hill pump from midway usa for $230 and has been going strong for over a year. They are very well made and has never let me down. The only con I can see is the price of a rebuild kit. I have never taken it apart so it is probably time to replace the internal dry pack and clean out any dirt.

bradyman1 · « **Reply #15 on:** May 31, 2012, 08:41:37 PM »

It is on its way back to sun optics. They sent me a shipping label and I mailed it yesterday.

bradyman1 · « **Reply #16 on:** June 06, 2012, 11:05:56 PM »

Well I got my pump back today. Sun optics got it out quick. They received it Friday and shipped it back on Monday. Here are some pics of the REBUILT pump.

I think I will contact them tomorrow.

Air Rifle Hunter · « **Reply #17 on:** June 06, 2012, 11:18:38 PM »

Definitely contact them! It looks like the only thing they did was maybe use some steel wool on it and that is being generous. That's a crock of poo doo if they try to pass that off as being "Rebuilt". At least they could have given you a new Main Tube when the "Rebuilt" it. What a joke. I hope they understand why you are not satisfied with the rebuilt pump.

bradyman1 · « **Reply #18 on:** June 06, 2012, 11:21:26 PM »

They told me thee resealed it, lubed it, and buffed the tube. I don't think I am being unreasonable, thr pump is MAYBE 2 months old with probably less than 50 fills. I would say closer to 30 or 40.

averagejoe · « **Reply #19 on:** June 07, 2012, 03:35:33 AM »

Wow, that thing is going to chew through seals. It is a defective unit and should be replaced.
