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

Purchased my first pcp air rifle and decided to start off with a High pressure hand pump. After many research and looking at people reviews, I had decided to get his one a try while in near future will most likely switch to a compressor. Upon receiving it, I decided to disassemble the pump and make sure it’s clean and had coolant. Sure enough there was no coolant at all. And found brass shavings inside the end connectors. This would have a disaster if it had clogged or tear up the o-rings if I had just assemble and used it out of the box. After assembling and adding coolant, I tested it and I can hear muffled sound coming out. It does hold pressure as I did the leak test at 2500 psi. Have yet to pump on the pcp rifle.

Would not recommend for paintball tanks or tiny scuba unless in great shape, like to workout, and have serious time. Adding 600 psi to a 48 tank took my full grown son several different times pumping over a few days. But for pcp would work, still would take at least 15 to 30 min continues pumping which it gets hot in 3 min so you have to let it cool. Also zero useful instructions but watch videos on line and very simple to make ready with just tool included. You may not think it is working at first but it just takes lots of pumping to see the gauge move.

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.

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
