Stator system of a progressive cavity pump

Operating method involves adapting of the stator internal dimensions during the operation of the e-pump to arising circumstances. The axial length of the stator lining consisting of a flexible material is changed. The stator lining is extended or shortened for the steady distribution of the pressure...

Beschreibung
Zusammenfassung:	Operating method involves adapting of the stator internal dimensions during the operation of the e-pump to arising circumstances. The axial length of the stator lining consisting of a flexible material is changed. The stator lining is extended or shortened for the steady distribution of the pressure or the tractive power along the longitudinal axis of the pump parallel to the running contact surfaces. An independent claim is also included for the eccentric screw pump.
