24V pumping unit for transferring WMO? - Steel Soldiers::Military Vehicles Supersite

I've got about 400 gallons of WMO another member gave me. Well today I finally got around to trying to transfer it to my holding tank with my hand diaphragm pump. That was rather optimistic.

After about 5 or 10 minutes I had all the settled water pumped out and started on the oil... too thick/sludgy.

Looks like there's alot of gear oil in it. No way am I going to be able to get it transferred through that hand pump.

So what about a 24V military pumping unit? You know the ones that come with two 600 gallon tanks? How well would that handle thick oil? Do you think dirty oil would hurt it at all?

Is there an exposed nut holding the handle on? Jam a socket in a gear reduced drill and pump away! I have done that many times.
Edit, that will only work on a rotary pump.

Sadly, it is not rotary. Back and forth operation, otherwise I would have tried that.

Even so, this stuff is really sludgy.

Your best/cheapest route is to build one of the SBC oil pumps on a 110 or 24v motor.

If you build a smc transfer pump with a 110 motor,try to find a motor that turns around 1150 rpm's, this speed works better for thicker oil.

What's an SBC oil pump? Junkyard engine oil pump?

Eta: Ok, I think I get what you're saying.

Basically just scavenge an old engine oil pump from a junkyard and couple it to an electric motor.

This picture should tell you what I think of this idea:

how about a air powered pump run it off the truck air system Harbor Freight sells one that used 8 PSI its the silver colored pump.

Small block chevy oil pump,these,when set up right can pump around 7 gpm up to about 12 feet.

My one concern about that is, how rough would that be on the compressor?

I know it's gear driven so it doesn't have an electric duty cycle... but still, I would think that kind of air would require it to run constantly. And I just don't know enough about deuce air compressors to know if that's a good idea.
