The pump comprises an upper portion and a lower portion. The upper portion is adapted to be connected to means for suspending the pump in the tube. The pump has a vertical direction extending from the lower portion to the upper portion. The pump further comprises an inlet for allowing the liquid into the pump and an outlet for allowing the liquid out of the pump. The pump further comprises a sealing means located downstream of the inlet and the outlet in the vertical direction, the sealing means being adapted to seal against an inner surface of the tube. The invention further relates to an arrangement for hydraulic drive of the submersible pump and to a semi-submersible unit comprising the submersible pump system.
