Jackson, MI – Melling will be introducing a brand new oil pump with asymmetrical helical cut gears for small block Chevys at the Performance Racing Industry Show in Indianapolis. The “Shark” pump offers smoother output than a traditional spur gear oil pump, along with reduced power requirements and higher volume output. The pump has a cast iron housing with steel helical cut gears.
Helical Asymmetrical Oil Pump Technology 
R&D Code Name: “Shark Tooth Pump”
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 reduction in the pressure ripple from
the pump will also provide benefits to the distributor and camshaft drive.
