NettetGood pump efficiency means that a pump is not wasting energy in order to maintain its performance point. No pump is 100% efficient, however, in the work it has to do to transfer liquids. When selecting a pump and motor combination, consider not only the total current demand but future demand to ensure your selection has the capacity to … Nettet5 to 10 hp; peak efficiency is at 7.5 hp. A motor ’s efficiency tends to decrease dramatically below about 50% load. However, the range of good efficiency varies with individual motors and tends to extend over a broader range for larger motors, as shown in Figure 1. A motor is considered
