  • Patent number: 11181121
    Abstract: The invention relates to centrifugal pumps and can be used for pumping oil and other fluids along pipelines. A pump comprises a set of strength elements in the form of reinforcing ribs connecting a pump housing to the surfaces of supporting feet of the pump. The fastening surfaces of the feet are situated along the central axis of the inlet and outlet lines. The feet are connected by the reinforcing ribs to the inlet and outlet lines and to bearing assembly housings and connect the housings to one another. The feet themselves are connected to each other in pairs by ribs which pass below the base of the pump housing. The base and the cover of the housing are configured with interior chambers which form an inlet and an outlet. All of the ribs are integral with the cover or the base. The invention is directed toward increasing the reliability and working life of the pump by reducing vibration loads and increasing leak tightness while at the same time minimizing the material requirements of the pump structure.
