Eugene Vogel EASA Pump and Vibration Specialist
When working with pumps, you are sure to encounter instances where the pump curve is referenced, along with a number of parameters associated with it. A key parameter of the pump curve is the Best Efficiency Point (BEP). This simple concept of an operating point that yields the most efficient operation is not difficult to visualize. For electric motors, efficiency varies with load; the best efficiency being at about 75% load. However, with rotodynamic pumps – which include centrifugal and axial flow pumps – there are four key parameters to be considered, one of which is efficiency. These four parameters are head, flow (aka capacity or volume), power and efficiency.
