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. Additionally, our vegetable oil pumps were not reliable for pumping cold motor oil, so we engineered a new Heavy Duty Oil Pump. Baldor custom made us a robust 1700RPM motor for moving motor oil, gear oil etc. Voila, a portable and fast gear pump for high viscosity fluids.
