@@cobyleo3343 I have the TOPA pump. Filling a 200 bar Benjamin Maximus. Works good so far after one year of normal use. Just need to pump slow, and take your time. Watching your video for fixing in the future. Nothing lasts forever. But for now, it's a good pump for the money.
I have to advise you the key part you missed. At 3:37, you forgot yo clean the o-rings of the pump piston. There are few o-ring inside it, especially the o-rings in the top (you have to remove the top screw to see it). It is a very important part but not mentioned in your clip.
I watched your video several times and repeated to clean the seals but in vain. My pump bumped back every time so is unable to inflate the PCP. Replace the tiny o-ring inside the pump piston at 3:37, and it works as usual now.
At 1:43 that screw is so tight on my pump cant get a firm grip on it either im afraid to damage the outer tube if i use any tools to hold onto the pump
Very good
thank you,
wow
where can i find,full reparationset voor O-rings en rubber,do you have a site where i can finding the set
How to unscrew the cylinder for third stage, the one which third stage piston move?
you can see my video ,if you can not open it,you can send me your side video
mind did not have coolant... do I just add water or let it be?
not water,Car engine coolant，
@@cobyleo3343 Dont use water or engine coolant. It will leak through the orings and potentially corrode stuff or clog it!
@@heksogen4788 It will seal well when it is installed.So please tighten the sealing screws properly.
@@cobyleo3343 I've had leak at the bottom of the tube, the threads of the first stage brass cup at the bottom had corroded because of the leak. The pump has VERY thin o'ring there and i think it doesn't seal well. I've seen other chinese companies placing thicker oring there. Beside -brass, steel and conducting agent can create galvanic cell, maybe that's what happened.
