Powder Metal Pump Components – Rotors, Gerotors and Bushings | SinterWorks

Pump builders use powder metallurgy for gerotors, rotors, vanes, bearing bushings and thrust washers because the process delivers near-net shape geometry and controlled porosity in one pressing. This SinterWorks page covers the material grades used for pump components (FC-0208, diffusion-alloyed steels, bronze), the dimensional and surface finish tolerances achievable, porosity control for self-lubricating bushings, and the leak-test and dimensional inspection steps applied before shipping. SinterWorks supplies sintered pump components and structural PM parts from its Nanjing plant.
