Abstract
A pump casing made of sheet metal has an outer casing having a suction nozzle, and an inner casing housed in said outer casing and spaced therefrom. A resilient seal is disposed in a gap defined between the outer casing and an inner casing. An impeller is rotatably disposed in the inner casing with a clearance defined between a liner portion of the inner casing and the impeller. The resilient seal is effective to absorb deformations of the outer casing, such deformations of the outer casing are not transmitted to the inner casing.
