Hydraulic Oil Pump - Horsepower vs. Pressure and Volume Flow
Calculate the power required for hydraulic pumping based on flow rate, pressure, and efficiency.
Hydraulic Oil Pump - Horsepower vs. Pressure and Volume Flow
The power required for hydraulic pumping.
Formula
PHP = q × p / ((μ / 100) × 1714)
Where:
- PHP = horsepower (HP)
- q = flow (gpm)
- p = required pressure (psi)
- μ = overall efficiency (%)
Example
For a pump with flow 20 gpm and 1500 psi increase in pressure at 100% efficiency:
PHP = (20 × 1500) / 1714 = 17.5 HP
