APWONE High Pressure Hand Pump, Stainless Steel Air Pcp Pump 4500psi 3 Stage for Rubber Boat Inflatable Kayaks

Worked great filling a 2000psi pcp, for about a week. The oring in the check valve at the base of the unit blew, no problem, replaced it with one supplied in the kit. 3 fills later it blew, replaced, 4 fills, it blew, tried 3 different size orings, dif springs tentions, nothing worked, 2-4 fills every time. Sending back.pics compare it to the hatsan version. At first glance, they look the same. Upon further examination the hatsan seems to be a lot better quality.First, what the pictures can't show you. The foot stands on the cheap one, wont hold the pump up well. The hatsan stands are a lot more sturdy.The cheap ones rubber handles won't stay on, hatsan handles seem to be glued on better.Cheap one has a shorter hose with no storage loopNow what you can see in the picturesThe oring that keeps blowing on the cheap one doesn't have a seat for the oring, just a sharp edge that cuts into the oring when its trying to hold the pressure from coming back into the pump. As you can see in the pics, the hatsan has a tapered seat for the oring. Hopefully the hatsan will hold up better. I didn't go through the rest of the pump, but just what I've seen the hatsan is better quality. It cost a little more but trust me when your shooting groups and your pump fails every other fill, it's a real bummer.

Worked great for the first fill up on my benjamin bulldog. On the second fill up though it failed. It started leaking oil from somewhere and no longer prevented flow back into the main cylinder of the pump. I would push down and it would auto rise back up without filling the air rifle at all. I've issued a replacement through amazon and will update review once I have it and get a chance to use it a few times.

Bought this pump to air up my pcp air rifles. I have owned the high dollar ones but when they failed I decided to give this much cheaper one a shot. And I gotta say, you get what you pay for. I tried to pump up my Hatsan Flashpup, from about half full. I pumped about 150 pumps and was no where close to filling it to where it needed to be. I have checked all fittings and added plumber's tape to every screw possible, and it just doesn't pump up very good. If your looking for a nice pump and trying to save money, keep looking, cause this isn't the one for you.

I bought this pump for a PCP air rifle. I noticed the handle at the top of the pump was loose. Upon further inspection, the O ring seal for the top of the piston was torn. I had not even used the pump yet and it already needed to be rebuilt. The instruction manual is in English, but it might as well have been written in Chinese. Whomever they have translating for them does not have very good grasp of the English language. I am a diesel technician by trade so I was able to figure out how the pump works to rebuild it. Frankly I believe I should just return this pump for one of a little better quality.

First pump I received would not reach a 3,000 PSI rating and became extremely difficult to near impossible toget a full downward stroke. It completely failed (Would not push air at all) shortly after. It was returned and promptly replaced. This pump appeared at face to operate but after following instructions and applying supplied lube where instructed it failed to maintain pressure. (air leak) I am returning it and asking for a refund. Sorry but when I by a product I expect it to work from the start and not have to play mechanic and rebuild it.

So far so good. We pumped our 200 bar PCP about a dozen times now and ( knock on wood ) the pump is still working.

This is the second one purchased. The first one was damaged in shipping before it arrived. This one was delivered opened and we will be returning as it does not work. Please seal the package ,seriously no tape or glue on the box.

Got my first one and pump for 2 hours and didn't get any kind of pressure. Tried for the same amount of time the very next day and still got nowhere. Returned it for a new one and the new one cam quick but I got about the same result only got to about 1000 psi the just stopped working. Mind you it took about 1 hour to get to that. I will be asking for a refund of my money. Do NOT BUY THIS ITEM.
