Rotor

A rotor is a key component of many pumps and machines. In pump technology, the term rotor refers to the rotating element that transfers the kinetic energy to the pumped medium. 

The rotor is one of the central elements used in progressing cavity pumps, where it rotates in an eccentric motion pattern to move the medium through the pump. The shape and design of the rotor precisely match the requirements of the respective application. This guarantees efficient and reliable pumping of even highly viscous, abrasive or sensitive media. The materials and surface finish of the rotor is decisive for the pump's longevity and performance, especially under demanding operating conditions.
