Gear/Power steering pump.
Can't an hydraulic steering pump be used as an oil pump by putting a motor
on the shaft? I wonder what the flow rates are on regular power steering pumps and what h.p. is needed to drive them. j/b |

Gear/Power steering pump.
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?

Gear/Power steering pump.
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. j/b "Mechanical Magic" wrote in message ...

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. Dave On Dec 16, 8:17 pm, "jusme" wrote: Thanks, Dave. I though so but wanted to ask.

Dave,
I THINK that the pump I now have is a gear pump. It will empty a barrel in ~ 10 minutes and is driven by an 1/3 horse motor. I will verify this tomorrow. It is not a p.s. pump but I am pretty sure that it is a gear pump. Will give update tomorrow. j/b "Mechanical Magic" wrote in message ... j/b 10 GPM is a lot.

I wonder what the flow rates are on regular power steering pumps and what h.p. is needed to drive them. j/b 10 GPM would take a 1.32 cu. in. positive displacement pump direct coupled to a 1725 RPM motor. That's at 100%----realistically you would need a pump in the 1.5 cu. in. area. Power steering pump is too small. Look around for a small gear pump. Cessna, Webster and Prince are common brands for small aluminum cased cheap gear pumps. If you get a motor with a C face on it, use a Buckeye flange and a Lovejoy style coupler to assemble it. |

Something along these lines
