Booster Pump Head Calculation Xls [better] Jun 2026

In industrial, commercial, and residential water supply systems, ensuring adequate pressure is critical. A booster pump increases pressure from a low-pressure source (like a municipal water main) to meet higher demand requirements. Calculating the required booster pump head correctly is the most crucial step in sizing the pump, ensuring energy efficiency, and preventing cavitation.

Pump head measures the mechanical energy a pump adds to a fluid. It represents the height a pump can lift a liquid vertically. Head is expressed in meters (m) or feet (ft), not in pressure units like PSI or bar. Why Use Head Instead of Pressure?

This total head is known as the , which consists of three main components:

A booster pump calculation isn't just a sum. It’s a balance sheet of energy.

Valves, tees, elbows, and strainers restrict flow and cause pressure drops. Your Excel template should calculate these using the :

Convert total fixture units to flow rate using Hunter’s Curve. This yields the flow rate in Liters per Second (L/s) or Gallons per Minute (GPM). Step 2: Measure the Static Head ( Hscap H sub s

Below is an example Excel spreadsheet for calculating booster pump head:

This is where the Excel grid truly earns its keep. Every elbow, every valve, and every meter of pipe steals energy.

Flow rate is equally important. For booster pumps, this is determined by adding up the water demand of all fixtures or processes running simultaneously. In building design, this is often done using fixture unit tables converted to GPM or LPS.

When using specific constants (like gravitational acceleration g = 9.81 m/s² or fluid densities), utilize absolute references (e.g., $C$5) so formulas can be dragged across rows without breaking.

To build an accurate tool, you must account for the following: A. System Static Head ( Hscap H sub s Elevation GainElevation Gain

You got the water to the top floor, but can it get out of the tap?
