WebSome pumps will only reduce in HP or amperage by 10% or 20%. Others will decrease in amperage by 50% to 60%. See the pump curves in Figure #1 and Figure #2. n Figure #1, the pump is reduced from 10 HP to 7 HP at low flow. In Figure #2, the pump reduces from 10 HP to 3.25 HP. Obviously the pump in Figure #2 will use less energy at lower flow rates. WebTDH is the total pressure the pump must generate to overcome elevation and friction loss and to provide the operating pressure to the heads. TDH is expressed in feet of "head" (1 psi, or pound per square inch = 2.31 feet of head). The theoretical power needed for pumping water is called water horsepower (whp) and is calculated by:
