centrifugal pump sizing|centrifugal pump impeller size chart : supermarket Best Efficiency Point (BEP) is the capacity at maximum impeller diameter at which the efficiency is highest. Specific speed (Ns) is a non-dimensional design index that identifies the geometric similarity of pumps. It is used to classify pump impellers as to their type and proportions. Most medium and larger centrifugal pumps have efficiencies in the range of 75 to 93 percent, while smaller pumps typically fall into the range of 50 to 70 percent. In contrast, large AC motors tend to have an efficiency close to 97 percent, and motors with ten horsepower or more can be designed to exceed 90 percent efficiency.
