  • Pump Terms and Definitions

    The term capacity is also used. Best Efficiency Point (BEP)– The rate of flow and total head at which the pump efficiency is maximum at a given speed and impeller diameter. Displacement (D)– For a positive displacement pump it is the theoretical volume per revolution of the pump shaft. Calculation methods and terminology may differ between different types of positive displacement pumps.
