Pump Power Calculator
Calculate hydraulic power, required pump shaft power and a motor power target from flow, total dynamic head, fluid density and pump efficiency.
Hydraulic power
1.63 kW
Pump shaft power
2.33 kW
Motor power target
2.68 kW
Formula and selection note
Hydraulic power = ρgQH. Shaft power = hydraulic power / pump efficiency. The motor target adds the selected margin. Final selection must use the pump curve at the duty point, NPSH available vs required, motor service factor, fluid temperature/viscosity, minimum flow, pipe-system curve and applicable mechanical/electrical standards.
