Abstract

Die Erfindung betrifft eine Kreiselpumpenanordnung mit einem Schneidwerk (1), das vor dem Zustrom des Mediums in ein Laufrad (2) angeordnet ist. Das Schneidwerk (1) weist eine Schneidfläche (3) mit Öffnungen (5) auf, durch die das Medium strömt. Ein rotierender Schneidkörper (4) liegt an der Schneidfläche (3) an. Der Schneidkörper (4) und das Laufrad (2) werden gemeinsam von einem Motor (11) in Rotation versetzt. Erfindungsgemäß ist dem Motor (11) eine Steuereinrichtung zugeordnet, welche das Laufrad (2) und den Schneidkörper (4) intervallweise in unterschiedlicher Rotationsrichtung umlaufen lässt. Das Laufrad (2) weist Schaufeln (16) auf, die sich in rein radialer Richtung erstrecken. Dadurch weist die Kreiselpumpe in beiden Drehrichtungen die gleiche Kennlinie auf.
