<strong>Centrifugal Pump Classification by Flow
Centrifugal pumps can be classified based on the manner in which fluid flows through the pump The manner in which fluid flows through the pump is determined by the design of the pum casing and the impeller. The three types of flow through a centrifugal pump are radial flow, axia flow, and mixed flow.
Radial Flow Pumps
In a radial flow pump, the liquid enters at the center of the impeller and is directed out along the impeller blades in a direction at right angles to the pump shaft. The impeller of a typical radial flow pump and the flow through a radial flow pump are shown in Figure 6.
