The progressive cavity pump as a particularly resistant pump
Conveying at optimized speed

Progressive cavity pumps belong to the rotary positive displacement pumps. The basic principle of the progressive cavity pump was invented in 1930 and is based on a rotor rotating in a stationary stator. The rotor has the shape of a screw conveyor with a large pitch and flight depth as well as a small core diameter and rotates "eccentrically" in the stator. The stator, in turn, has the shape of a matching, but a doubled thread worm with twice the pitch. Due to the geometry and the eccentric rotation of the rotor, cavities are formed in which the medium is enclosed and evenly conveyed from the suction to the pressure side; the second gear of the stator is used as a conveying channel for the medium. Based on this conveying concept, progressive cavity pumps convince with pressure-stable and speed-proportional conveying.
