ABSTRACT:
A submersible pumping system is disclosed for pumping cryogenic liquid from a reservoir in which a pump and motor unit is lowered to the bottom of a fluid transmitting casing in the reservoir. An isolation chamber is provided in the casing above the roof of the reservoir into which the pump and motor unit is raised for removal. A special sealing arrrangement is provided which maintains the casing and reservoir isolated from the atmosphere when lifting the pump and motor unit, yet allows a flexible suspension cable to be utilized.
