Abstract (en)
The multi-level centrifugal pumping device has a crankshaft housing (2) and a bearing carrier (13) connected to a pump housing. The bearing carrier supports a bearing of a shaft (3). The shaft carries a rotor (4) at an engine side and a propeller (7) at the pump side. The rotor and the propeller are arranged in a pump chamber (8). The bearing carrier is formed for supporting a cast housing unit (12) with a pressure connection (11) of the pump or a lining unit made from sheet metal.
