But if you want easier pumping. This will work, you just have to pump more.

And if you are the one pumping i would not let your air pressure get too low before topping off .

How long have you had each of those? And how much use do they get? Just curious how long these last.
Thank you.
 
I had them for year and I have gone through at least 15k pellets, my 4 stage pump stopped working after about 1 month. But it was just dirt in the last stage that I just cleaned out. It works but I don't use it.. The other two probably need cleaning now. I don't always have time to air up my midsized tank from joe and because the covid thing has less effect on freeway traffic. It's harder to get my tank topped off. I have not seen Joe in over a month and used the pumps exclusively during this time. If you hand pump over 3000 psi I would use the 4 stage. More pumping but not as hard. If you use a pneumatic pump like I do to pump two pumps and have a larger cylinder, use the cheaper one as they pump up to the presure faster. In reality I really abuse these pumps. As I have plumbed the intake of the pumps with pressurized air to pump it up faster as well as from time to time topped off the air tank when I did not have time to go to joe to top them off.

Took your recommendation for the pump after comparing them all. Received today and the only instructions was a 1 page flyer looking piece, that had very basic info regarding Pressure test, Running-In and an FAQ. Can you remember if yours came with a more detailed user manual of how to assemble or disassemble for maintenance? Seems like I'm missing something. Thanks
 
Doubt you are missing much, assemble, a bit of pure silicone oil on the inner shaft , have fun. That's it to start. Pressure check? Most come with a dead head, pop that in and pump up, bleed remove deadhead and fill rig.

Most are rather similar these days once you need a rebuild (maybe years, could be month's) here is just the 1st thing I saw on the internet and seemed a good guide.

Originally when hand pumps came out they recommended 50 stroked then lift handle and cool briefly and repeat. Always seem to last year that way. Technique is everything in pumping, lock elbows, squat dropping all body weight with back straight. Rewarding fun.

FWIW
Here's the one I bought on Amazon last October

SPRITECH PCP Hand Pump, 4 Stage​

I like it a great deal for a number of reasons
It has a moisture filter on the intake as well as the output side
Being 4 Stage (more strokes at less effort) I can actually hit 3Kpsi
Something I cannot do with a 3 stage pump

It does not get heavy use, but it is certainly a go to pump for the smaller reservoirs (Maximus, Disco, P-rod, etc)
I've even taken my Daystate Revere to 200Bar and a Sumatra Carbine to 3k.
It takes a while but gets the job done when the bottles are low & or the Yong Heng is down.
It's coming up on 3000 pumps and gets lubed as per instructions every 800

Here's the link

Hope this helps
Ed
