old'un Posted April 25, 2023 Report Share Posted April 25, 2023 My bottle is empty and needs a test, so I thought I would invest in one of these hand pumps to keep it topped up to its fill pressure of 190 bar, well I have read the instructions and plugged it into the gun and started pumping, it got to 1000 psi and the plunger is solid, even putting my full weight on it it will not go down or pull up, any ideas??? pump in question…https://www.ebay.co.uk/itm/325424849563 Quote Link to comment Share on other sites More sharing options...
scarecrow243 Posted April 25, 2023 Report Share Posted April 25, 2023 (edited) it could have got to hot you should always check the inside tube for heat if it starts getting warm stop pumping it to let it cool down also check the inner tube has some silicon grease on it i can use my gunpower pump up to 150 psi before it gets warm and i don't get to hot and knackered Edited April 25, 2023 by scarecrow243 Quote Link to comment Share on other sites More sharing options...
old'un Posted April 25, 2023 Author Report Share Posted April 25, 2023 no, not getting hot only pumped it to 1000 psi (68 bar) then it just goes solid almost like there it something stopping the air entering the gun. Quote Link to comment Share on other sites More sharing options...
scarecrow243 Posted April 25, 2023 Report Share Posted April 25, 2023 Hi was the gun empty of air if it was try cocking it some times some guns need to be cocked to refill them Quote Link to comment Share on other sites More sharing options...
old'un Posted April 25, 2023 Author Report Share Posted April 25, 2023 no, the gun has about 140 bar (2030 psi) in it, tried with it cocked and un-cocked, still solid, have you got one of these pumps? Quote Link to comment Share on other sites More sharing options...
scarecrow243 Posted April 25, 2023 Report Share Posted April 25, 2023 no but i have used a few i have a gunpower one now disconnect it from the gun and close the bleed screw and pump it to see if any air comes out the tube if it does do you have a plug that fits into the tube if yes then try pumping it up to see how far it will go if it goes above the 1000 psi then the fault is at the gun end if not its the pump that's faulty Quote Link to comment Share on other sites More sharing options...
old'un Posted April 25, 2023 Author Report Share Posted April 25, 2023 I have a blanking plug that fits in the end of the filling whip, have just tried this and I can only get it to pump up to 1000 psi then the plunger go’s solid, you can push it down a bit and also pull it up but if I take my weight of the plunger it just shoots back up an inch or two.

scarecrow243 Posted April 25, 2023 Report Share Posted April 25, 2023 the pump is faulty as it should be able to pump up to 3000 psi if its new return it if its not new it most likely needs new seals or return valve Quote Link to comment Share on other sites More sharing options...
Ultrastu Posted April 25, 2023 Report Share Posted April 25, 2023 That pump has failed . Your basically getting an air lock somewhere inside the pump .probably a leaking oring. Return it- you won't be able to fix it . I and others have tried to fix (with full seal kit ) expensive pumps and not succeeded . Quote Link to comment Share on other sites More sharing options...
scarecrow243 Posted April 25, 2023 Report Share Posted April 25, 2023 buying cheap pumps is not always a good choice the hills one i use to have was £150 the gunpower is £157.99 Quote Link to comment Share on other sites More sharing options...
Ultrastu Posted April 25, 2023 Report Share Posted April 25, 2023 I'd recommend a hills or and fx pump . I also have a cheap ebay pump it works but it's a very unpleasant workout . My fx mk4 is sooooo much better . Quote Link to comment Share on other sites More sharing options...
oldypigeonpopper Posted April 26, 2023 Report Share Posted April 26, 2023 (edited) Hello, what is their policy on returns ?, Mail seller the problem and see what they say, they might send new pump , or a return post , failing that and you get no reply issue a claim with eBay, it's not likely your loose, if they send a new pump, strip the broken one as it's most likely a seal or ?, Did you get a seal kit, these pumps are pretty basic engineered to strip down, look on Google for vevor pump faults as I am sure it's not a 1 off Edited April 26, 2023 by oldypigeonpopper Quote Link to comment Share on other sites More sharing options...
Shufti Posted April 26, 2023 Report Share Posted April 26, 2023 I had a similar thing with one of my chinese pumps locking up. Can't remember exactly but pumping it with the vent open cleared it ! Been fine ever since! Worth a try Quote Link to comment Share on other sites More sharing options...

Hello, I never had water in mine 🤔, but that is where the filter helps to only have clean air going into a PCP after 50 or so pumps, I used a few drops of silicon oil inside the tube, not sure if that is the right oil but it worked for me, as for the sellers reply, 🤔 what they have said all seems a lot of hassle, have you googled on these pump faults just in case other buyers have same problem, ? Or you could just start an eBay complaint and see what happens, you may just have a one off duff pump but that is no good when you need it now Quote Link to comment Share on other sites More sharing options...

Ultrastu Posted April 27, 2023 Report Share Posted April 27, 2023 If you or anyone else .opens up the pump .you have voided any warranty and given up any chance of a claim .they know this so are asking you to go this route . Xxxkers Why only a 25 % refund when it's 100 % broken /doesn't work . Quote Link to comment Share on other sites More sharing options...

The thing is knackered .I've had this on an old pump and a mate had similar on a hills pump mk4 .he bought a seal kit and tried to fix it .(and he knows his way around pcps no problem) but this pump would not be fixed . He returned it back to hills .who fixed it and returned it in a week. With no charge .all excellent service .pump better than new .
