    Pump Head Curve for STS1072RV1 motor

    Hello,

    I recently replaced my old single speed pump motor for a two speed century STS1072RV1. Do any of you now where can I find the system head curve data? I am trying to figure out GPM on both low and high speed with this need motor.

    Thanks,

    Aroldo

    Motors do not have head curves, only pumps have head curves. But low speed of a two speed pump will always be about 1/2 of high speed.

    What is the pump make & model #?

    Also, why do you care about flow rates? If you are trying to figure out turnover for run time, don't bother. Just read the article about run time in my signature.
