Factors responsible for the efficiency of a centrifugal pump

When you want to achieve optimum performance and reliability in a centrifugal pump, you must operate the pump close to its BEP (best efficiency point). The BEP is the most stable and suitable operating point for a centrifugal pump. At best efficiency point, the hydrodynamic unbalanced load of the centrifugal pump is at its minimum.

Centrifugal pump

Like most pumps, a centrifugal pump converts rotational energy, often from a motor, to energy in a moving fluid. A portion of the energy goes into kinetic energy of the fluid. Fluid enters axially through eye of the casing, is caught up in the impeller blades, and is whirled tangentially and radially outward until it leaves through all circumferential parts of the impeller into the diffuser part of the casing.
