Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber (casing), from which it exits. Main Components used are: 1. Involute Casing (Blue) 2. Shaft (Skin) 3. Impeller (Orange) 4. Cover (Yellow)
