Abstract

Die vorliegende Erfindung betrifft eine selbstansaugende Kreiselpumpe mit einem Saugdeckel (2) mit Ansaugöffnung (3), einem Laufrad (5), einem das Laufrad (5) aufnehmenden Strömungskanalgehäuse (6), einer druckseitigen Öffnung im Strömungskanalgehäuse (6) und einem im Umfangsbereich zwischen der druckseitigen Öffnung und der Ansaugöffnung (3) vorgesehenen Unterbrechungsbereich (22). Um eine selbstansaugende Kreiselpumpe mit den eingangs genannten Merkmalen zu schaffen, welche bei einem möglichst einfachen Aufbau auch für Sterilanwendungen geeignet ist, wird erfindungsgemäß vorgeschlagen, daß alle mit dem Pumpmedium beaufschlagten Teile der Pumpe aus einem Sterilitätsanforderungen genügenden Material hergestellt oder mit einem solchen beschichtet sind und daß der Saugdeckel (2) und das Strömungskanalgehäuse (6) sowie alle weiteren vom Pumpmedium beaufschlagten, statischen Bauelemente der Pumpe mit zu den Funktionsräumen hin freiliegenden Dichtungen gegeneinander abgedichtet sind.
