摘要： 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.

摘要： A full circumferential flow double suction pump has a pair of pump assemblies mounted on respective opposite ends of the rotor shaft of the motor mounted within an outer frame casing. The motor is positioned within an outer cylinder such that an annular space is defined between the outer frame casing and the outer cylinder. A discharge port connects with the annular space. A pair of cylindrical cup-shaped pump casings are connected to respective opposite ends of the outer cylinder for housing the pump assemblies. A header pipe connects the suction nozzles of the cylindrical cup-shaped pump casings to each other and has a suction port defined therein for introducing a fluid therethrough and through the suction nozzles into the pump assemblies.
