A centrifugal pump has continuous or assembled body, inlet and pressure branch pipes, covers and bearing units each of which has two bearings holding the shaft with working wheel (wheels) and unloading device. Bearing units are additionally equipped with bushings between which paired bearings are placed. At that between the bearings and the outer rings of the bearings there are gaps, besides that in axial direction of the pump the bushings are connected to the bodies of the bearings with resilient elements as helical springs. |
