Abstract

Die Erfindung betrifft eine Kreiselpumpe mit einer zwischen Pumpenwelle und Antriebswelle angeordneten Magnetkupplung und mit einem Spalttopf (10) im Magnetspalt zwischen dem inneren Magnetrotor (14) der Pumpe und dem äußeren Magnetrotor der Antriebswelle, wobei im Inneren des von der Förderflüssigkeit durchflossenen Spalttopfes (10) der innere Magnetrotor (14) an einem rohrförmigen Lagergehäuse (8) gelagert ist, das die Pumpenlaufradwelle (3) umgibt, die auf der dem Pumpenlaufrad (2) abgewandten Seite Befestigungsmittel (15) für den inneren Magnetrotor besitzt, der zwischen dem Lagergehäuse (8) und dem Spalttopf angeordnet ist, wobei im Ringspalt (25) zwischen dem Lagerbereich des inneren Magnetrotors und der Innenwand des rohrförmigen Lagergehäuses (8) eine schraubenförmige Nut (27) in der Innenwand des rohrförmigen Lagergehäuses (8) und/oder in der Außenwand des Magnetrotorlagers (26) angeordnet ist, die die Flüssigkeit durch die Lager (4-7) fördert, die zwischen dem Lagergehäuse (8) und der Welle (3) oder der Wellenhülse (12) angeordnet sind.
