Pressure times flow, times a constant depending on the units being used.

Flow times Pressure times SG over Constant times Pump Efficiency. Constant depends on units. Loads of websites give the formula.

Oh, I would take the volumetric flowrate, multiply by the pressure rise, and divide by the pump's efficiency, Boss, unless the pump manufacturer's technical data sheet doesn't give the motor size for the pump, which is extremely unlikely.
