  • Flow-stabilizing volute pump and liner
    Patent number: 5127800
    Abstract: Uniquely contoured interior surfaces have been found to stabilize the flow patterns through centrifugal pumps of the volute type, especially pumps having wide impellers and wide volutes for pumping slurries. The contoured interior surfaces may be provided in the pump casing, but are preferably defined by a volute liner. The interior surfaces comprise a volute region and a discharge nozzle region which both are at least in part contoured interior surfaces and which cooperate to provide a flowingly contoured interior surface of changing axial cross-section.
    Type: Grant
    Filed: April 12, 1990
    Date of Patent: July 7, 1992
