ABSTRACT:
The invention is connected with an installation or plant for storing oil and similar petrol products in several underground storing rooms each communicating with a common oil-filled pump chamber housing submersed pumps for pumping out oil from any of the rooms. Selective pumping requires valves for selective connection of room outlet pipes with a pump inlet pipe. Submersed location of those valves in the pump chamber, according to the prior art, involves several disadvantages such as the need of draining the complete system for repair and maintenance work on the valves, and, difficulty to remote-control the valves. These advantages are, according to the invention, eliminated by the use of a dry valve chamber sealed-off from an oil-containing pump chamber housing submersed pumps.
