        How to determine the power of centrifugal pump prime mover
        Time:2011-4-14
        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.
