Booster Pump Calculator — Calculate Pump Requirements and Costs

Booster Pump Calculator

Calculate the right booster pump for your water system with our comprehensive calculator. Determine pump specifications, power requirements, and installation costs based on your project needs.

Step 1: System Requirements

30 GPM
40 PSI

Understanding Flow Requirements

Flow rate (GPM) depends on the number of fixtures you need to supply simultaneously. Pressure increase required is the difference between existing pressure and desired pressure at the farthest fixture.

Pump Power Calculation Formula

Pump Power (HP) = (Flow Rate (GPM) × Pressure (PSI)) / (1715 × Efficiency)

To calculate required pump power: Multiply flow rate by required pressure increase, then divide by 1715 (conversion factor) times pump efficiency percentage.
