An introduction to energy consumption in pumps -

Jan 01, 2008  A pump with a capacity of 100 m 3 /h, a difference in pressure of 1 bar and an efficiency of 75% will require an output at the pump shaft of (100×1)/ (36×0.75) = 3.7 kW. If we set the efficiency of the transmission and the electric drive at 90%, then the power taken from the grid is 3.7/0.9 = ca. 4 kW.
