newbie hand pump question...Vevor 4 stage pump? 30% more effecient????
- Thread starter Joshua777
- Start date
I know this is an old post but I just got a Vevor 4-stage pump. When setting up, they have a plug to insert in the fill line so you can test-pump the unit. Can't get past 3000 psi; I think I would have to gain at least another 100 lbs. to have enough weight to push the pump handle further to increase pressure beyond that. Any like experiences??

@GerryR, Is this your first hand pump - as in do you have experience with others that worked fine?
If it is your first one, you probably just have to work on the technique - even guys under 150 pounds have no issue with a properly functioning 3 stage pump with the right technique, and a four stage shouldn't be any harder (although enjoying doing it is another matter). The best technique is to pull the pump handle up, pause for a second or two, and then start the downstroke and get up over the handle and lock your elbows and sort of fall onto the pump handle in a controlled way letting your momentum carry the handle down as you bend your knees to hold form. It is a bit of an art and you can figure it out with practice.
If you have experience, and feel there is something wrong with the pump, then sorry - I have no experience with that model, or four stage hand pumps in general (mine is a three stage). I hope you get is sorted out.
