Abstract

A submersible pumping arrangement, specially adapted for pumping cryogenic fluids from reservoirs, comprising a tubing adapted to hang vertically from the roof part to the bottom part of a storage tank, a foot valve that normally closes the end of the bottom of said tubing, a vertically displaceable stuffing box that normally closes the upper part of said tubing, a discharge outlet provided with valve adjacent to the upper part of said tubing, a pump and motor unit that loosely fits into said tubing having a opening opening downward, adapted to be applied to the valve at the bottom of the tubing to open the valve, to communicate the content of the reservoir with the interior of the pump, said pump having a discharge outlet communicating with the tubing, means of sealing between the tubing and the pump that impede the circulation into the tubing except through of the pump, means suspending the motor and pump unit through the displaceable stuffing box in the upper part of the tubing, and means for raising and lowering said stuffing box to allow the suspension means to raise the pump and motor unit away from the valve in the bottom of the tubing, to allow the valve to close and to allow the pump and motor unit to descend against the valve to open the valve, and means in the upper part of the tubing to purge the inside of the tubing, with what the removal of the pump and motor unit is done without risk and without loss of fluid or pressure, purging the cryogenic fluid in the tubing through the pump and leaving through the open valve back to the tank, going up next the cable gland for raising the pump and motor unit to allow the closing of the valve and then removing the pump and motor unit from the top of the tubing for repair ion or substitution.
