Sintered inner & outer rotor sets are precision-matched components designed for reliable oil and fluid pumping. Manufactured using advanced powder metallurgy, these rotor pairs ensure smooth flow, consistent pressure, and long service life in demanding pump applications.
Each inner and outer rotor is engineered to work as a perfectly matched set. The optimized tooth profile delivers stable torque transmission and accurate volumetric control. This design minimizes internal leakage, improves pump efficiency, and ensures steady fluid delivery even at varying speeds.
These rotor sets are produced using net-shape sintering technology, achieving tight dimensional tolerances without extensive machining. Controlled density and uniform material structure ensure excellent strength, wear resistance, and precision fit between the inner outer rotor assembly.
Sintered rotor sets are widely used in oil pumps, lubrication systems, and hydraulic pump assemblies. They are suitable for automotive engines, industrial machinery, and fluid handling systems requiring dependable performance.
Offered as matched sintered rotor sets, these components are ideal for OEM production lines and bulk procurement. Consistent quality, interchangeability, and scalable supply make them a reliable choice for manufacturers seeking long-term performance and cost efficiency.
