Abstract

Die Erfindung betrifft eine Exzenterschneckenpumpe und ein Verfahren zu deren Betrieb. Abweichend vom bisher bekannten Stand der Technik, wo verschleißbedingte Änderungen an der Innengeometrie des Pumpenstators stets mit radial wirkenden Spannmaßnahmen behoben wurden, geht die Erfindung davon aus, dies durch eine Änderung der Länge der Auskleidung herbeizuführen.
