Billet Oil Pumps

Melling’s break-through billet oil pump design effectively reduces size, weight, and complexity while significantly improving the pump’s performance and durability. The exclusive helical asymmetrical gear design significantly reduces the pressure pulsing and resulting cyclic loading on the drive shaft which is typically found in gear pumps. This reduction will improve the operation of the distributor resulting in less spark scatter and wear on the drive gear.

The robust design will work even in the most demanding solid motor mount applications. The anodized hard-coating applied to the housing and cover dramatically increases the surface hardness providing a durable wear surface. Due to the compact design the billet pumps will fit in the same space required by the original cast iron pump.

Melling’s billet pumps consume less power as compared to other competitor’s pumps which use thrust bearings. Omitting the bearing s eliminates a catastrophic failure mode.

The integral oil pickup incorporates a stainless steel wire mesh for better filtration and improved pump efficiency. Optimized pickup and inlet design minimizes the effects of cavitation. The result is that the oil entering the pump is super-charged to provide improved pump performance at high operating speeds.

The length of the pump’s drive shaft has been increased to allow for additional support in the cover. Increasing the support eliminates shaft deflection which allows the gears to run true at high RPM levels.

Billet pumps are available in both stock volume and high volume versions. The high volume pump gears provide 25% additional pumping capacity but require less horsepower to turn when compared to traditional oil pumps.
