What is BEP Good for?
When designing a system the pump specifier attempts to match the best pump to the system by establishing priorities. Many systems, perhaps even most systems, do not have a steady continuous flow rate allowing a pump to operate only at its BEP. Therefore the system designer may chose a pump which has a BEP at the flow rate which the pump will operate at for the longest periods of time, while also operating at flows Off BEP with the least amount of radial thrust and vibration (Widest Operating Window or Range).
