Construction & Design:

The Melling 10452 oil pump features a cast aluminum housing that is hard coat anodized to resist corrosion and improve thermal management. The cover is made from cast iron with a phosphate coating, providing enhanced durability against wear and chemical exposure. The internal rotor is crafted from billet steel, ensuring strength and longevity under high-stress conditions. This combination of materials and coatings results in a robust oil pump capable of maintaining consistent pressure and flow in demanding performance applications.

The adjustable relief valve uses a threaded pressure plug instead of a traditional cup plug, allowing for precise tuning of oil pressure with included or optional springs. This design flexibility helps tailor oil delivery to specific engine requirements or modifications.
