Abstract: A wet-running centrifugal pump includes an electric motor (1) and a centrifugal pump (7) which is driven thereby. The electric motor (1) has a rotor (4) which is rotatably arranged within the stator (3). A canned pot (13), which carries a motor-side bearing for the rotor (4), is provided between the rotor and the stator. Moreover, a bearing plate (19) is provided, which carries a pump-side bearing for the rotor (4), wherein the bearing plate (19) is fixed on the housing side, and in the region of the pump-side bearing immerses into the canned pot. A radial seal (20) is provided between the bearing plate (19) and the canned pot (13).

Abstract: A pump assembly (1) includes a rotor axle (45) extending along a rotor axis (R), an impeller (12) fixed to the rotor axle (45), a pump housing (11) accommodating the impeller (12), and a drive motor with a stator (17) and a rotor (51). The rotor (51) is fixed to the rotor axle (45) for driving the impeller (12). A rotor can (57) accommodates the rotor (51). The rotor can (57) includes a rotor can flange (63). An electronics housing (13) has a cap (21) including a first material (139) forming a front face (19) of the cap (21). The front face (19) extends essentially perpendicular to the rotor axis (R). The first material (139) is at least partially overmolded with a second material (141) at an inner side of the cap (21). The second material (141) is more heat-conductive than the first material (139).

A stator housing (13) accommodates the stator (17). The stator housing (13) is secured to the pump housing (11) by a bayonet ring (113). The bayonet ring (113) is resiliently spring-loaded for axially biasing the stator housing (13) towards the impeller (12) against the pump housing (11).
