ABSTRACT:
A centrifugal pump assembly comprising one or more bowl castings each housing an impeller and also two or more individual fluid passageways for the flow of fluid discharged by an impeller to the next impeller, the passageways having some exterior walls defining the exterior of the assembly. By changing the number of the individual passageways, the specific speed of the pump, i.e., the ratio of the amount of energy imparted to the fluid and the amount of fluid being pumped, can be changed.
