Recommend a hydraulic pump

I've got a JD2 model 32 bender and I'm tired of my pos air over hydraulic pump. I want to upgrade to electric without going full retard on the money. Big project coming up that will need a fair amount of 2" tube so I might as well bite the bullet and buy a pump. Which one is is everyone using?

You've got to match the flow of the pump to the requirements of the piston. Get a pump with little flow but the right pressure, and it'll be slower than air over hydro. Vice-versa, it'll be too quick.

This was sized for a 40t ram in a hydraulic press operation based off some plans I found a year or so ago. Might work for you:

Thanks, that could work but I would really prefer something with a push button pendant instead of a manual valve. I need to be somewhat mobile while bending tube.

I went to my local hydraulic shop and they built me a kti pump. Bends 2" like butter. Its 12v, it has the push button on so only on when I need it to.

I, like a lot of people, used this unit on my conversion:

I am using a log splitter valve though, not a pair of buttons to a solenoid valves.

i should also add why i haven't hooked the pump i bought up yet...

whats you shop air pressure at? i used to run the compressor so it would hit 140psi tops, unregulated to all the shops air drops, so pressure could get much lower before it kicked on again. now i have it so the compressor kicks off at 175psi as its rated, and regulated to 140psi at each drop. getting rid of all 1/4" air line and only having 3/8" has made a big difference as well. i put off regulated drops and bigger line for a long time and in hindsight it should have been much higher on my list of priorities.

with consistant 140psi to the air over cylinder. it bends much faster, still not as good as an electric over would but close enough i dont think i'll get to hooking it up for a while. in the meantime i'm using the power pack to run all the porta-power attachments as its way better than a hand pump in most cases.

also if you can or dont mind using a 12v powered unit like on a dump trailer they are much less expensive, and have a hand pendant like you want. they are around $250 on amazon i've bought a half dozen of whatever was cheap for dump trucks and trailers and they have all worked without issue

I'm running 120 psi but, my pump is starting to leak and was never fast enough. I don't mind spending for a 120v unit, 12vdc would be more trouble than it's worth. I work in the film biz and travel for work, this needs to be really user friendly to accommodate the various snowflakes I work with!

With a single solenoid, does it hold the ram position until you hit the "down" button?

Are you using a double acting cylinder or a standard Power team single? I've got a SA cylinder, is there a spool valve that will advance, hold or release as needed?

Wci-12v-da-3000. Its 3000 psi pump. You can pick sa or da, or i think combo sa/da, you can pick the size of your tank. You can pick your gpm, I think mine is 2gpm. You can only purchase from a dealer of kti.

Those 120v ones on Amazon were kind of sceetch to me, they never really accurately reveal the gpm. The price of the kti was the same price as all the other ones and all I had to do was hook up to a battery and push a button. Its super quiet and is only running when I push the button.

I'm using a double acting, it's a 3x24" IIRC.

I believe you just need a 3 way 2 position to run a single acting cylinder. Center is closed (hold), one way is fluid from pump to ram, the other way is ram to reservoir.
