We use this style of pump at work for pumping thick gloopy oils contaminated with particles:

Will pump nearly anything! Although they'll use a huge amount of air.

HOW MUCH!!!???

Looking at the rotors, it looks very much to me like the same principle as a hydraulic pump off a digger. If it is, it would rip your fingers off, spit them out without changing its speed, and then start on the rest of your hand.
So long as it doesn't hit metal.

Like the sound of that!

reminds me of the guy (forget who) who put a car windscreen motor (its slow geared) on a hand rotary pump. cheap cheerful powerful and 12 volt. = nice, that can pump veg with inch bore i believe...

could even use this off your car batt on waste oil collections  sort the wireing and you could get 2 speeds and intermitant, yes nice bit of kit.

I actually have one of those in my garage.  Just need a 12v windscreen motor :-)

i use a onga trash pump, 720 ltrs per min, run it just over idle and from an ibc on the ground to one on the truck 2 minutes max.
i did purchase a 15 gpm gear pump http://www.wvodesigns.com/shop/clearance/15gpm-goldstream-waste-oil-monster-pump-head-only.html  the freight is the killer here,  will put it on a 240 volt motor but would like to try a electric scooter motor on it 1st. there cheap and can run them on 12v or 24v if you want it to go faster, i put one on a small hand chaff cutter @ 12v it works okay more torgue needed,
after purchasing these items i found "chev small block oil pumps" worth a google  also on utube.
