A circulating pump with an electric motor, which comprises a rotor and a stator, is proposed, the rotor being mounted on a spherical bearing which comprises a sliding body with a convex spherical surface and a bearing bushing with a concave spherical surface and which is fluid-lubricated, in which pump a flow system for passing lubricating fluid through a lubricating region between the sliding body and the bearing bushing is separate from a gap between the stator and the rotor.
