Abstract

Die Erfindung betrifft eine Kreiselpumpe mit einer dem Pumpenlaufrad vorgeschalteten Zerkleinerungseinrichtung für faserige oder stückige Beimengungen in der Förderflüssigkeit, wobei die Zerkleinerungseinrichtung durch einen mit dem Pumpenlaufrad umlaufenden, mit mehreren Schneidkanten versehenen Schneidkopf und einen mit dem Schneidkopf zusammenwirkenden, im Gehäuse der Kreiselpumpe feststehend angeordneten Schneideinsatz gebildet wird, wobei der Schneidkopf mit mehreren, im wesentlichen axial verlaufenden, durch Stege begrenzten Ausnehmungen versehen ist, wobei an der saugseitigen Stirnseite des Schneidkopfes ein oder mehrere Schaufeln angeordnet sind. An der saugseitigen Stirnseite des Schneidkopfes (6) ist ein Aufsatz (9, 41, 51, 61, 65) angeordnet. Der Aufsatz (9, 41, 51, 61, 65) weist einen rotationssymmetrischen Grundkörper (23, 42, 57) auf, von dem ausgehend die Schaufeln ausgebildet sind. Mindestens eine Schaufel ist als ein profilierter Flügel (10, 43, 52, 62, 63) gestaltet.
