  • Patent number: 4492514
    Abstract: A method and means for providing a protective environment for submerged pumps are described. For a submerged water pump a shell or casing is installed to enclose at least a lower portion of the pump, and a protective fluid medium, typically compressed air, is introduced in the shell to exclude water from contacting the pump operating components or lines when the pump is not in use. Means are provided for quickly removing the protective medium and permitting water to enter the pump when it is desired to put the pump into operation.
