Hi,

I'm looking for a 12V DC Hydraulic pump that can run at 1800 PSI and 10GPM continuously for 5 minutes, and run for up to 30 minutes in the hour.

I've looked over some of the commercial sites, but was hoping someone here may have first hand experience of these things.

It's to drive a milemarker winch.

Merv.

That is about 10 1/2 hp. At 12V, you would be drawing about 800 amps.

In other words, I don't think that is going to happen. You would need to run your pump off the engine, or PTO.

So if I settled for 5 gpm, Does that translate to 400 amps? Still a Lot, but twin optimas should take it? No?

If the best that can be done with electrics is going to take 400+ amps, I'll look again.

I was planning to run a pump direct drive from the front of the engine, but I've been told that this can crack crank shafts as the vibtration from a high volume oil pump is serious. (When direct drive to the crank).

I think I'll examine a twin V belt setup from the engine. One V belt wont be able to handle the HP required.

Do you have PTO provisions? That is by far the best way to run a hydraulic pump.
