A centrifugal pump is a rotating machine in which flow and pressure are generated dynamically. The inlet is not walled off from the outlet as is the case with positive dis- placement pumps,whether they are reciprocating or rotary in configuration. Rather, a cen- trifugal pump delivers useful energy to the fluid or “pumpage” largely through velocity changes that occur as this fluid flows through the impeller and the associated fixed pas- sageways of the pump; that is, it is a “rotodynamic” pump. All impeller pumps are rotody- namic, including those with radial-flow, mixed-flow, and axial-flow impellers: the term “centrifugal pump” tends to encompass all rotodynamic pumps | McGraw-Hill PUMP HANDBOOK THIRD EDITION IGOR J.
