Melling Performance Shark Oil Pumps

Melling has improved the heart-beat of the traditional internal gear pump. It is now significantly smoother through the use of new helical asymmetrical gears. The new gear design provides the engine with an improved flow of oil without the usual pulsing found in traditional gear pumps.

The new gear design provides the engine with an improved flow of oil without the usual pulsing found in traditional gear pumps. The reduction in the pressure ripple from the pump will also provide benefits to the distributor and camshaft drive.

The Shark oil pump offers a significant reduction in pressure ripple (pulsing), a reduction in torque ripple in pump drive, an improved distributor operation – reduction in spark scatter, and an improved distributor gear wear & intermediate shaft wear.

The oil pump is also tighter, providing an improved sealing of gear tips to housing, a reduced internal leakage and improved efficiency and performance.

The Shark is also quicker, with an increased inlet vacuum and faster priming.
