The frequency of oscillations appearing during the electrical centrifugal pump operation is related with the rotor rotation frequency and is actually constant. To reduce the vibration of the constructions critical components the dynamic dampers are often used when vibration is transferred from the protected machine to the auxiliary assembly which vibration poses no danger to the system as a whole. The paper discusses the possibilities of this idea implementation for protection of the electrical centrifugal unit and presents three possible options for consideration.
