ABSTRACT:
The invention relates to a vertical submersible pump assembly, comprising a pump assembly casing which contains a hydraulic drive motor with a drive shaft. On the pump assembly casing a pump house is secured, and a pump rotor which is connected with the pump shaft and provided in the pump house, a transport conduit from the pump house, which transport conduit extends above the pump medium, and two drive medium conduits from the above said pump medium and down to the pump assembly casing. The vertical submersible pump assembly is characterized by the fact that the pump house is divided radially outside the pump rotor, the external ring shaped pump house portion being connected with the transport conduit. Each drive medium conduit comprises a releasable conduit means which when removed permits a unit compressing pump assembly casing with the drive motor, the pump rotor and the inner pump house portion to be pulled up.
