Abstract

Die Erfindung betrifft eine Kreiselpumpe mit einem Pumpenläufer (2), der in einem Gehäuse (1) angeordnet ist. Vor dem Zustrom des Mediums in ein Laufrad (3) ist mindestens ein Schneidwerk (7) angeordnet. Das Schneidwerk (7) weist eine Schneidfläche (8) und einen rotierenden Schneidkörper (9) auf. Durch Öffnungen (10) in der Schneidfläche (8) strömt das Medium. Die Schneidfläche (8) und der Schneidkörper (9) sind mit einer Anpresskraft (F) gegeneinander verspannt. Erfindungsgemäß wird die Anpresskraft (F) aufgrund der Rotation des Pumpenläufers (2) erzeugt.
