ABSTRACT:
An electrically powered pumping system for extracting liquid from a deep container includes an electric motor having a rotor with a drive shaft connected thereto. A centrifugal pump has a driven shaft, and a shaft extension is coupled at one end to the drive shaft of the electric motor and at an opposite end to the driven shaft of the pump. An elongate support member has a first end for receiving the electric motor and a second end for connection to the centrifugal pump. The support member has a central passageway extending from the first and second ends for passage therethrough of the shaft extensions, and a plurality of spaced bearing members are provided in the support member for rotatably supporting the shaft extension therein.
