Abstract: A circulation pump assembly, with a wet-running electrical drive motor (4), includes a pump casing (6) as well as a motor housing (22) which is connected to the pump casing (6). The motor housing (22) is a combined stator and electronics housing that accommodates a stator (18) of the drive motor (4) as well as motor electronics (34). The motor housing (22), at a first axial end (24) facing the pump casing (6), is closed by an air gap sleeve (16) of the drive motor. The motor housing (22), at a second axial end (26) which is away from the pump casing (6), includes an opening (42) closed by a cover (28). An interior of the motor housing (22), in a region adjacent the first axial end (24), is filled with a potting mass (40) surrounding the stator (18) and the motor electronics (34).

Abstract: A wet electric motor for a pump includes a stator casing, a stator arranged in the stator casing, and a can, wherein first resilient pressure elements are arranged inside the stator casing in such a way as to exert a compressive force in the direction of the can on at least parts of the stator, as well as to a pumping set with such a wet electric motor.
