ABSTRACT:
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.
