ABSTRACT:
A wet-type rotor pump which is particularly suitable for feeding coolant in motorcar engines comprises a pump wheel. By the pump wheel, a feed medium is fed through an intake channel into a discharge channel. Via a common shaft, a motor armature of an electric motor is connected with the pump wheel. The motor armature is surrounded by a slit pot, feed medium flowing around the motor armature to cool it. The shaft is supported by two radial bearings, one radial bearing being arranged in a supporting element. The supporting element that is arranged within the intake channel further comprises an abutting surface on which a flow surface of the pump wheel abuts to take up axial forces.
