I have a Benjamin 3000psi hand pump that I bought from Pyramid to use until I figure out what tanks/compressor I'm going to get. It works, but I weigh about 160 and with my body weight, can't pump much more than 2600. That's sufficient for Mrod but barely. My question is whether the pumps rated for 4500 have a different piston configuration or design, or do they just have a higher rated gauge on them? Thought is that maybe I can get more psi from a 4500 rated pump... or just wasting $$ ? Looked at Vevor and 4-Uncles on amaz*n Any advice?
differences in hand pump performance?

I had a Hill and also have one of the $50 pumps off Amazon rated 4500. Both were WORLDS ahead of the Benji pump I had. I think it could be 3 stages vs 4 stages.

Amazon ones work great. Real performance difference is which one empty out your wallet better. At 180lbs I don’t even try to get to 4500 psi, but non of the guns I use hand pump for needs more than 3000 but I did fill my impact once with it to 250 bars for fun.

Sodbuster,
Don't waste any more on a handpump, move to compressor. Yong Heng is very popular on this forum, search in archives for information, think we've discussed it every way possible. Biohazardman's Fact Sheet is very helpful and can be found throughout. Good Luck, WM

well i never bought a bunch of handpumps to compare lol .. id say if you have a benji stick with it theyre nice pumps, mine i got originally in 2012 with my first pcp and ive never replaced an oring in it yet, works fine .. i weigh about the same and never had a problem going to 3k, trick is not to rush it, lift slow and steady and drop your weight on it .. id watch a youtube if needed and break it down, make sure everything is dry, free, and lubed .. too much lube, or i imagine moisture, can make them feel locked up, and leaving moisture in it will pit the surfaces .. but yeah i like the benji, wouldnt out more money on another handpump although i think the chinese pumps are fine to .. not a benji, but functional ..

If you consider yourself a casual PCP shooter, than I think a hand pump might be for you. Especially if you were shooting at 35 foot pounds and less.
I have good success with my FourUncles hand pump purchased on Amazon for about $70. I’m shooting 15.89 grain .22 Hades @ 920 fps=30 fpe…it takes a little under 2 pumps/bar from 100 bar to 250 bar, so 275-300 pumps(reg is set to 95 bar) I get well over 100 shots per fill so less than 3 pumps/shot isn’t bad IMO!
However, if I’m shooting slugs at 50 fpe it’s probably more like 5 or 6 pumps/shot…not fun.

I only use my hand pump for my crosman guns that tops out at most 3000 PSI. With such little tank filling from my SCBA tank is rather nerve racking! I get over 1 pump per shot for my 1701(4FPE) and 2 pumps per shot for my 1720 but that's at 12 FPE.
