Pump Head & Power Calculator
Estimate the total dynamic head and the pump power (HP / kW) your system needs from flow, lift, pipe length and required pressure. Adjust the inputs, then get an engineered pumping design.
Your system
TDH = static lift + friction + residual pressure. Friction uses a typical allowance; final selection needs the pump curve, pipe sizing and NPSH check.

Thanks! Our team will send your tailored pump & hydraulic design within one business day.
Indicative estimates only — not a binding design. Actual pump selection depends on pipe sizing, fittings, velocity, NPSH and the manufacturer's curve.
