When a pump housing for an electromagnetic pump for the propulsion of a conductive liquid in a cooling circuit, in particular for the cooling of electrical components, said pump housing comprising an upper part and a lower part which assembled constitute a pump chamber having an internal surface, said lower part being provided with openings for pipes for the cooling circuit, said openings pointing inwards to the pump chamber, said pump housing being additionally provided with two openings for electrodes, said electrodes pointing inwards to the pump chamber and being arranged on opposed sides of the pump housing and being equipped with electrodes (8), is improved to the extent that the internal surface (5) of the pump chamber (4) is provided with a coating (10) having electrically insulating properties, it is ensured that the electrical scattering losses are reduced significantly. When, additionally, electrodes having a low transition resistance and being capable of ensuring a good contact face to the conductive cooling liquid are provided, electrical losses in electrodes and in the body of the pump housing may advantageously be reduced. |
