A self-priming pump assembly comprises a series connection of a liquid ring pump functioning as a rotating displacement pump and a normally-priming centrifugal pump. The self-priming pump assembly improves the fluid mechanics conditions for the flow of fluids toward and into a return line through the inclusion of a first connection opening in the meridian plane of the centrifugal pump that possesses a bulge enclosing a sector of the longitudinal axis of the first connection opening, where the bulge is one-sided and oriented toward a rotary axis of the pump assembly, and the bulge continuously expands, directly or indirectly, the first connection opening toward the impeller plane. At its end section facing the impeller plane, a transitional surface of the bulge continuously transitions into the lateral boundary surface, or an inner peripheral wall of the ring channel adjoining the lateral boundary surface.
