Abstract: A stator-rotor system of an eccentric screw pump including a rotor with a rotor screw and a stator with an internal thread. The stator includes a support element and an elastomer part. The support element surrounds the elastomer part in sections around the whole circumference. The stator-rotor system includes a mechanism for adjusting the stator, having two adjustment elements arranged on the stator-rotor system, which are distance-variable relative to one another. In a first working position the two adjustment elements have a first distance from one another and in a second working position, a second distance. The cross-section and the length of the elastomer part of the stator in the second working position are changed compared to the cross-section and the length of the elastomer part in the first working position.

Abstract: The invention pertains to an eccentric screw pump with a stator-rotor system, which includes a rotor with a rotor screw and a stator with an internal thread. The stator has a support element and an elastomer part, wherein the support element encloses the elastomer part sectionally over its entire circumference. The stator-rotor system has a mechanism for adjusting the stator, which is coupled to at least one sensor for determining actual operating parameters of the stator-rotor system by means of a control unit that activates the adjusting mechanism with consideration of the actual operating parameters determined with the aid of at least one sensor.
