Propeller pump for pumping liquid, including: an axially extending tubular pump housing having an inner surface, an axially extending pump core having an envelope surface, at least one axial portion of the pump core enclosed in the pump housing. The pump core includes a propeller having a hub and at least one blade, and at least one guide vane that includes an upstream leading edge and a downstream trailing edge, and that in the circumferential direction includes a pressure side and a suction side. The guide vane extends between the inner surface of the pump housing and the envelope surface of the pump core. At the leading edge of the guide vane a connection angle between the suction side of the guide vane and the envelope surface of the pump core is larger than 90 degrees. |
