1. A wet rotor pump comprising an axial flux motor, which comprises a stator and a rotor, wherein the stator is disposed in a dry zone and the rotor on an impeller is disposed in a wet zone, having an inlet line for a fluid to be pumped by the impeller, and having a bearing for the impeller, wherein the bearing is disposed at one end of the inlet line, and the bearing supports the impeller in such a way that the impeller has one axial degree of freedom, wherein the inlet line extends through the stator and the bearing in the axial direction, wherein the bearing is a plain bearing which is used to radially support the impeller and axially support the impeller on one side as an abutment for the magnetic attraction force exerted by the stator onto the impeller;
wherein the bearing is formed, on the containment-shell side, by a bearing bush disposed in the end region of an inlet connecting piece of the inlet line and, on the impeller side, by a plain-bearing element, which has a sliding surface which engages in the bearing bush; and wherein the plain-bearing element has a circumferential edge, which is disposed so as to form a stop at the bearing bush when a magnetic attraction force from the stator acts on the rotor in the axial direction. |
