    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).
