1. The pumping process begins when the fluid to be handled enters the pump at its entrance, directly into the center of the impeller, which serves as the primary suction point. 2. As the impeller rapidly rotates, it exerts a strong centrifugal force on the incoming liquid. This force propels the fluid outward along the circumference of the impeller. 3. Simultaneously, within the core of the impeller, a low-pressure zone forms due to the mechanical action, creating a vacuum that draws more fluid towards it.

The design principle of a cast iron centrifugal pump involves water spinning in the impeller to generate centrifugal force, which forces water outward along the casing walls, reducing pressure at the impeller's center.
