Ultimate 12VDC Gear Pump

Tired of whimpy oil pumps? 

We've gone through 4 years of development on these pumps.  Upgrades have included a custom US Made Baldor motor, viton seals to the pumpheads, scrapping troublesome pressure regulators.   We have had numberous requests for a 12VDC version of out popular Porable Monster Gear Pumps so here it is.   Baldor custom made us a robust 1800RPM motor for moving all types of oils:  diesel, hydralic oil,  motor oil, heavy gear oil etc.   This eliminates having to run your 120V pump through an expensive inverter.
