Pump Head Curve for STS1072RV1 motor

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.

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.
