Improved Racing has partnered with Marco Fluid Tech to bring you these high-performance electric gear oil circulation pumps. We tested several pumps ands chose Marco for their high flow efficiency relative to their size and weight, which makes them ideal for circulating fluid in performance automotive transmissions, differentials, and transfer cases.
These pumps are self-priming and can operate in the absence of fluid. They feature helical bronze gears which guarantee constant pressure, heavy duty cycles, and quiet operation.
This smaller pump was able to pump SAE 30 weight oil at 25°C (77°F) at 0.88 GPM. A operating temps closer to 100°C, flow rates will be significantly higher, approaching 1.5 GPM.

NOT recommended for pre-oiling unless the system includes a pressure bypass after the pump. This is a positive displacement pump and "dead-heading" the pump will cause the pump to fail.
