    Abstract: The invention is related to a centrifugal pump with an existing pump housing made of plastic material that can be processed through injection molding, having a first housing section, featuring a suction nozzle and a pressure nozzle, a second housing section supporting an electronically commutated DC motor and a split case, a motor housing section that closes a dry chamber separated from a wet chamber by the split case in which a stator and an electronic component are arranged, and a permanent magnet rotor that is mounted in the wet chamber in such a way that it can rotate, and drives a pump impeller that reaches into the pump chamber. The electronic components are arranged on an electronic circuit board aligned at right angles to an axle and parallel to a base of the split case. The electronic circuit board is in heat conducting contact with the base. The task of the invention is to cool electronic components sensitive to heat in a simple way and with a high degree of efficiency such that a simple installation of the electronic components is guaranteed and only a small number of parts is required, the construction space being as small as possible. According to the invention, this problem is solved by the fact that one or several conductors of the electronic circuit board are in heat conducting contact with the base.
