Airgun PCP Pump 4500PSI High Pressure Hand Pump 3 Stage Pump Chamber PCP Air Pump

Works good

pumps Beeman QB chief to 2000 psi in 5 minutes

I had to install the gauge with some teflon tape and then the quick connector at the gun end was a little loose and leaked once it got up to 2000 psi. Once I tightened that the pump worked well. I charged my Marauder from 2100 psi to 2900 psi in a little over 4 minutes including a couple short breaks and with 85 pumps. It was a work out but very manageable for a 57 year old guy. I suppose it could be difficult if you don't have much weight to put to it. It is an excellent shoulder work out though. The outer tube was warm after but not hot and there was a little oil around the base where the outer tube bottoms out while pumping.The bad part is the horribly translated instructions that are almost worthless. As a mechanic I can sort of make them out but they try to explain how to oil the pump for maintenance but it is very unclear. There are several YouTube videos that show how to set them up and service them though so a little research will explain better.

Great build ,amazing heavy metal base foot construction.You don't need to spend any more on brands ,,comes with total rebuild kit and glow in the dark oil gauge.

The media could not be loaded. This is my second one, both had the same issue. The pump is not designed to pump air. It’s not designed to push air at all. The plunger they use to interact with the valve is way too small to even touch to valve, and instead actually creates another seal around the valve, causing what little air is coming out to be trapped behind the plunger. Video shows what I’m talking about. Forgive my terminology, I am a gunsmith, not a pellet gun master, but I know when something isn’t right. Video shows that the plunger chokes the rest of the air, shows how it doesn’t even contact the gate, and shows just how deep the gate is in comparison to the plunger that’s supposed to hit it. These was not designed to be used, ain’t no way, unless they forgot the same part in both the ones they sent me, this is a scam.

I live in an area without any paintball stores close. Driving hours to the nearest place was so inconvenient, it never happened. I needed a solution and didn't want to spend so much money on a machine that may blow up in my face without proper maintenance and I'm not interested in all that. Just let me pump it up manually.I gave this a try and after researching, I figured I could take some time each day to add air. Well, it took me about an hour, off and on, to get my tank filled to 3000 psi. It really wasn't that difficult and I could have kept going but that's how much I fill my tanks. It was super easy to connect and disconnect. It gets hot though. But it works.I'm so glad I now have an in-house, self reliant solution. Saves me so much time and money.Works perfectly!

Instructions aren't 100% clear and the house might have a leak

I checked the thread for shavings found just a little bit from where they were threading the brass removed it and put some Teflon tape on it as I was putting it together. They say let’s just put a few drops of oil in them, but they get pretty warm, so far it seems to be a good pump . Pumped up both my rifles and a few tanks last night. Got a hell of work out what I did lol today’s date is 3/24/25 I just had to put a new hose on my pump my fault though for picking it up by it still going strong. I think it’s a wonderful poem. Does great job. I recommend to check the threads before using. I highly recommend it.
