10 GPM is a lot.

I don't think you are going to get it with a single P/S pump. I think
they are more in the 1 GPM range (and a few hundred psi). Maybe with
the proper belt/pulley. If you have the pump at the barrel head, self
priming should not be a problem. A 5/8" garden hose only puts out ~3
gpm. Even if you run a P/S pump at high rpm's, I think you are going
to starve the pump, since the inlet is too small.

Thanks, Dave. I though so but wanted to ask.

I want to empty 55 gallon barrels in around 5 minutes. These will contain
oil. Pressure is not critical. Self-priming is very important.

Sure, they work just fine, assuming you get the rotation right. We
had a home brew EDM for years, P/S pump circulated hyd fluid. It was
run by a 1/3 hp motor. (But, it only needed to move a cyl with a few
pounds load.) So, as to hp, it depends on the load, not the pump.

What are your flow and pressure requirements?

Can't an hydraulic steering pump be used as an oil pump by putting a

on the shaft?

I wonder what the flow rates are on regular power steering pumps and what
h.p. is needed to drive them.
