Abstract
The invention relates to an eccentric screw pump and a method for its operation. Unlike the previously known prior art, where changes to the internal geometry of the pump stator caused by wear were always remedied with radially acting clamping measures, the invention is based on bringing this about by a change in the length of the lining.
