8GPM, 12 Volt DC Portable Oil Transfer 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 oils. This eliminates having to run your 120V pump through an expensive inverter.
