General Components of Centrifugal Pumps

A centrifugal pump has two main components:

A rotating component comprised of an impeller and a shaft

A stationary component comprised of a casing, casing cover, and bearings.

The general components, both stationary and rotary, are depicted in Figure 2. The main components are discussed in brief below. Figure3 shows these parts on a photograph of a pump in the field.
