Abstract
A centrifugal pump with an existing pump housing made of plastic material that can be processed through injection molding, the pump housing 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 electronic components are arranged, and a permanent magnet rotor that is mounted in the wet chamber in such a way that it can rotate, thereby driving a pump impeller that reaches into the pump chamber. The electronic components are arranged on an electronic circuit board parallel to a base of the split case. The electronic circuit board is in heat conducting contact with the base.
