From what I've gathered so far that pump should be around 1 gal/min which should move my ram 1/2" per second which would be perfect for a tubing Bender. Someone please correct me if I'm wrong.

Would running this pump at 3400 rpm be OK? I have the motor already off an air compressor. It's going to be used for a tube Bender with a 3x1.5x24 cylinder. http://www.surpluscenter.com/Hydraulics/Hydraulic-Pumps/Gear-Pumps/0-12-cu-in-DYNAMIC-GPF1020PA-HYD-PUMP-9-7763-D.axd Thanks

Could I get some input on this cylinder? This is the only thing I can find so far that fits my needs assuming that the clevis mount on the ram comes off so I can have a threaded ram. http://m.ebay.com/itm/190907078755?nav=SEARCH

This place is awesome, thanks!

Thanks for all the replies. I think I have the pump figured out, do you think 1-1.5 gpm will be enough? I don't want to wait for the ram all day but I want to have good control when it's under load.

So a 3hp 1800 rpm motor with the pump I posted before would give me 3190 psi at 1.56 gpm?

So this pump with a 2hp 2000rpm motor should give me 3190 psi, right? http://www.surpluscenter.com/Hydraulics/Hydraulic-Pumps/Gear-Pumps/0-20-cu-in-DYNAMIC-GPF1034PA-HYD-PUMP-9-7765-D.axd

I'm shooting for 20-30 tons, a 5" cylinder with a 2" ram at 3000 psi should put me there at 25 tons. Not sure if that's a common size cylinder but that's just what messing around with a calculator got me.

So I'm building a hydraulic press and have no issues with the frame but the hydraulics are making me scratch my head. I'm thinking about a 5" flange mount cylinder. My question is about the pump, will a 2 stage log splitter pump like this be enough for this size cylinder...

They are 3' tall, I'm 6,3" and it seems to be a good height for me. :thumbup: Edit: I had a brain fart, there actually 3' 6"

X2 that's exactly what I need for my shop. Very nice restorations, everything looks better than new. It's always nice seeing a clean, organized shop too.

I'm planning on using a 4 way hydraulic valve to control it. Not sure if I should have one for each machine or just put one on the unit. Might get annoying having the lever separate from the press or bender.

That's exactly what I was looking for, thank you!

Do you have any pics?

I looked around ebay but haven't found anything worth bidding on yet, I'm going to keep looking. What kind of pressure/gpm should I keep in mind as a minimum? I want to at least have 20 tons for my shop press.
