ABSTRACT:
A centrifugal pump includes an impeller which is attached to a drive shaft, a multipart pump housing which is partly made of plastic material and contains an intake chamber positioned on the drive side of the impeller and a spiral-shaped pressure chamber, a bearing support disposed in the region of the intake chamber being made of metallic material, and the pump housing is provided with an intake flange on the drive side and a housing cover in the region of the pressure chamber. In order to reduce weight and manufacturing cost, the intake chamber is bounded on the one hand by the bearing support and on the other hand by a housing part which is made of plastic material and surrounds the bearing support to which it is connected, preferably so as to be detachable.
