摘要： A rotary pump with a plastic pump housing, that can be processed by injection molding, with a first housing part defining a pump space, which is connected to a second intermediate housing part accommodating an electric motor with a wound core stator. The rotary pump includes a plastic split core, the wound claw pole stator being mounted on the split core and a permanent magnetic rotor being mounted to rotate within the split core. A plastic motor housing part defines a motor space, wherein at least three axial and parallel split core ribs are provided between the split core and the claw pole stator, the ribs being distributed about the periphery of the split core at predetermined angles relative to each other. A return ring has first and second end sections, the return ring being connected to the wound claw pole stator, so that the first and second end sections are welded to each other. The stator is press-fit onto the split core via the ribs. At least three axial-parallel housing ribs protrude radially inward and are formed with the motor housing part, the axial-parallel housing ribs being distributed on the inside periphery of the motor housing part. Finally, the stator is press-fit into the motor housing part via the housing ribs.
