A rotary pump (1), which can be operated by an electronically commutated DC motor (56) with an axial gap, with a dry space (54), in which a wound stator (55) is accommodated, and a fluid-fillable pump space (13), in which a permanent magnetic pump impeller (5) is accommodated to rotate, the pump impeller (5) being separated by a split plate (18) from stator (55), which is connected to a return ring (27), to which several poles (15) are connected, and a circuit board (17), and is in heat-conducting contact with it, and includes a heat conducting element (10) from a good heat conducting light metal. The heat conducting element (10) consists essentially of a disk (40) aligned at right angles to the motor shaft or an annular disk with a coaxial tube (39) extending in the direction of the pump impeller in one piece with it, open or closed toward the motor shaft, and that the circuit board (17) is connected to the heat-conducting element (15) on the side facing away from the pump impeller (5).
