1, first using the following formula to calculate the pump shaft power
![]() Where: Q - pump rated flow, m3 / h; H - pump rated head, m; r - medium weight; η - efficiency of the pump rated conditions,%; Pa - pump rated conditions of shaft power, kW. 2, select the appropriate safety factor K, to calculate the prime mover is equipped with power P P = K·Pa P = K · Pa When Pa ≤ 15kW time, K = 1.25; When 15kW When Pa> 55kW time, K = 1.1 3, the reference specifications of the original motivations to select the right mover. |
