摘要

The auxiliary device for pumps working on a permanent magnet (10) rotation principle has a flushing pipe of rigid or flexible design, and starting from the pressure side of the pump effects forced flushing of the internal magnetic rotor chamber. The externally located facility uses a defined amount of the pumped medium for flushing.
