WanPower 70018 Airgun PCP Pump High Pressure Hand Pump, Up to 4500 psi, Safe and Convenient

It seems to work fine and is capable of well beyond 4500psi per my testing with the hose end plugged. I've only used it for an Mrod to 3kpsi and it seems just fine. I like the folding feet and overall it's good for a chinese pump and the price paid. The seal on the vent plug did not seal by hand tightening so I used pliers, and this makes it more difficult to vent and tighten each time and I assume will cause an early failure of the seal.There is no moisture collection so be sure to dry your gun out and oil it now and then or it will corrode the internals. Specifically the threads of the main tube which will make it difficult or even impossible to take apart, and at some point the threads will fail which is very dangerous. So do yourself a favor and check, often, regardless of what pump you buy. There are pix online of guns corroded from this so check those out.

Got this to go with my new Ataman AP16, which has a 4350 PSI fill pressure. My old Benjamin pump (for my Marauder) doesn't go that high, so I needed something better. This pump does the trick at a very reasonable cost. Seems a bit easier to get to 300 bar (4350 PSI) with this pump than it was getting to 250 bar with the Benjamin. I had one small problem, which was that air was leaking out from the hole in the side of the pump body. After an email to the seller (who responded within minutes), I realized I simply hadn't tightened the bleed valve screw enough. For anyone wondering how much effort these pumps require, I am just over 200 pounds, and by the time it gets up to 4000 PSI, I'm putting pretty much all my weight on the handle. You won't find a hand pump where that isn't the case. After all, 4000 PSI is a LOT of pressure. Any hand pump will take significant effort to get that high. But at least this one takes less effort than the Benjamin, which is itself a pretty decent pump.

I have used this for about 40 fills. My only complaint is the bleed screw. It takes a few times to get it to seat right. But, once it seals, the pump works well. I took a chance on the inexpensive pump and so far, I am pleased.

I use this pump with my Benjamin Marauder .22 pellet rifle. I have had it about a month and a half and have around 40 fills through it. It is well built and easy to pump. I can take my marauder up to about 2900 psi in under 4 minutes. It is good exercise and you don't have to mess with filling tanks. This is much cheaper than other pumps out there and works just as well or better. Strongly recommended.

Nice PCP pump. It will get up to 4500, tried it with the dead head. The bleed-off screw leaks as pressure goes up and needs to be re-tighten.

Was the cheapest PCP hand pump on amazon at the time i bought it. Works as intended. Had to get an adapter to make it fit Hatsan PCP fill probes, but it is working great. If it has a catastrophic failure somewhere along the line I will update my review.

It does the job just have a problem with Conversation building up in the pump

Stay away from this seller and from this product. First of all, they will not send you the exact item you see in the picture. I ordered this and was planning to re-fill my air rifle this weekend. I received the pump on Friday as it was scheduled but when opened the box I saw a black pump not the one you see in this picture. The wrench came with it and the connections were not the wright stuff. Very poor quality. I would stay away from this seller and this pump.
