For myself and others that think in Imperial units.

I'll assume this one curve is for pump at full speed. I used typical pump performance relationship to derive the curves for operating the pump at 80%, 60%, 40% & 20% rated speed.

If you take the pressure across the pump at the various pump speed it will provide the restriction curve for flow through block, heads and radiator
