Abstract

Die Erfindung betrifft eine Kreiselpumpe mit einer zwischen Pumpenwelle und Antriebswelle angeordneten Magnetkupplung und mit einem Spalttopf im Magnetspalt zwischen dem inneren Magnetrotor der Pumpe und dem äußeren Magnetrotor der Antriebswelle. Im Inneren des von der Förderflüssigkeit durchflossenen Spalttopfes ist der innere Magnetrotor an einem rohrförmigen Lagergehäuse gelagert, das die Pumpenlaufradwelle umgibt, die auf der dem Pumpenlaufrad abgewandten Seite Befestigungsmittel für den inneren Magnetrotor besitzt, der zwischen dem Lagergehäuse und dem Spalttopf angeordnet ist. Der Ringspalt zwischen dem Lagerbereich des inneren Magnetrotors und der Innenwand des rohrförmigen Lagergehäuses ist in seiner radialen Breite kleiner als der Ringspalt zwischen dem inneren Magnetrotor und dem Spaltrohr.
