Do these pumps actually work?

It works, the question is how big of a bottle are you filling and how much time do you have to do it...

Used one for six years and still working. But just bought a compressor so I will keep it for a back up.

March 5, Wineel High Pressure Hand Pump arrived from Amazon, paid $50. Worked great on Umarex Gauntlet but is a real workout on FX Wildcat MK3 (.30) and M3 (.25.)
Filling new M3 yesterday pump blew small O ring from inside center plunger right up metal shaft. Tank was at 200 bar. Checked out several repair videos and tore it apart. NO LIQUID COOLANT! No wonder got so hot. One you're checking out states is liquid cooled, as in both repair videos. Pump will work without fluid but runs hotter and will damage rubber seals. I've heard you can verify liquid installed by shaking, maybe good idea. I'll be filling mine with mineral oil or antifreeze, but going Yong Heng very soon.

I give mine 60-100 slow steady pumps, then take a break, so the pump and me can cool down Lol

I do 40 pumps, 15 minute cool down, 40 pumps, 15 minute cool down, repeat. Also, full up, pause, full down, pause. Wasn't bleeding pump between breaks. During break, with gun at 200 bar, big, loud whoosh. Didn't know problem then, took a day to figure out and repair. Liquid coolant would have helped pump stay cooler and to cool down more efficiently. I'll bleed pump at breaks now, but need to install coolant first. Upon disassembly, was surprised to find black, greasy gunk on everything. Think Chinese need to improve lubricant choices. Cleaned everything and used quality silicone for lubrication. Much smoother now.

I got mine to 5000 psi. It just takes a while so I have to pump two at the same time to reduce the time required to get the presure up.

I used a Benjamin pump for the first 10 years and now i got a couple of compressors and gotten spoiled.I had to rebuild that old Benjamin pump more than a few times and i also have one of the Chinese pumps like the one in the link that i got before i got the compressors and it worked fine,actually better than the Benjamin.
