Our sintered oil pump gerotors are engineered to deliver consistent fluid displacement, superior durability, and long operational life for OEM applications. Manufactured using advanced powder metallurgy (PM) processes, these gerotors ensure high dimensional accuracy, reduced friction, and stable performance across demanding operating conditions. Ideal for high-volume engine and pump assemblies, they meet the strict quality and reliability standards required by global OEMs.
The inner and outer rotor pairs are precisely designed to maintain optimal clearances, ensuring smooth oil flow and minimal internal leakage. The gerotor mechanism provides high volumetric efficiency by creating expanding and contracting chambers that enable continuous, pulse-free oil delivery.
Key design highlights include:
These design features make our PM gerotor components ideal for engines requiring efficient lubrication with minimal energy loss.
Our gerotors are manufactured using high-grade sintered PM alloys, selected for excellent strength, wear resistance, and thermal stability. The controlled sintering process ensures:
Advanced tooling and process control guarantee repeatable quality, making these engine pump parts suitable for automated OEM assembly lines.
For OEMs and large-scale buyers, our sintered oil pump gerotors offer significant operational advantages:
