ABSTRACT:
An arrangement including an electric motor driving a pump is provided. The arrangement is delivering a process fluid along a flow path, which flow path extends along a gap between a stator and a motor rotor of the electric motor. To avoid rotor dynamic instability caused by hydrodynamics in the gap flow, guiding elements are provided in the flow path.
