Pump Part Load Efficiency at Wayne Calvert blog

Pump Part Load Efficiency. Plev weighs the efficiency of design load as shown in the chart below, with the pump operating at 100% of flow for only 1% of the time, 42% of flow for 75% of the time, and so. Centrifugal pumps can approach 94 percent efficiency, but typical efficiencies are 55 percent for small pumps and 70 percent for large pumps. Modern ac induction motors have recently approached 99 percent efficiency, but most often are 91 percent to 95 percent at near full load conditions. This article examines a better way to evaluate pump life cycle costs and operating pump efficiency—the part load. The residential cooling curve shows the most part load degradation, followed by the boiler and heat pump heating curves.
