Hydraulic Pump Drive Horsepower
Fluid HP = gpm x psi / 1714, drive HP = fluid HP / efficiency. 10 GPM at 2000 psi, 0.85 efficiency -> 11.7 fluid HP, 13.7 drive HP (size the motor to 13.7 and round up); at 100% efficiency the 2.0 HP gap is the pump loss. A sizing aid; the pump and motor data govern.
Formula and source
fluid_hp = gpm x psi / 1714; input_hp = fluid_hp / efficiency.
The fluid-power pump horsepower relation (fluid HP = gpm x psi / 1714), by name.
