Abstract

Die Erfindung betrifft eine Nassläuferpumpe mit einem Axialflussmotor, der einen Stator (110, 112, 114), einen Spalttopf (116) und einen Rotor (122, 124) aufweist, wobei der Stator und der Spalttopf in einem Trocken bereich und der Rotor an einen Impeller (128) in einem Nassbereich angeordnet sind, mit einer Einlassleitung (134, 156) für ein durch den Impeller zu förderndes Fluid (108), und mit einem Lager (154, 156) für den Impeller, wobei das Lager an einem Ende der Einlassleitung angeordnet ist, und das Lager den Impeller mit einem axialen Freiheitsgrad lagert, wobei die Einlassleitung in axialer Richtung durch den Stator, den Spalttopf und das Lager hindurch verläuft.
