Wet rotor pump comprising a permanent magnet

A wet rotor pump comprising an axial flux motor, which has 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, wherein the rotor is formed of one or more permanent magnets made of samarium cobalt (SmCo), wherein the one or more permanent magnets are not encapsulated and are therefore exposed, unprotected, to the fluid to be pumped, at least on the surface thereof opposite the stator, having a containment shell, which is disposed in the dry zone, having an inlet line for a fluid to be pumped by the impeller, and having a bearing for the impeller, wherein the inlet line extends through the stator, the containment shell, and the bearing in the axial direction.
