Avoid these frequent mistakes when building or using an XLS calculator:

To ensure your Excel sheet produces a valid engineering result, always verify the following factors before selecting a final pump:

If your system uses from an underground tank or positive suction from a city main

Good for preliminary design, but not a substitute for professional hydraulic analysis.

If you are designing water booster systems, take an afternoon to build or audit your XLS. Your pumps will last longer, your customers will have stable pressure, and your energy bills will thank you. If you are designing water booster systems, take

Where:

Commercial fixtures need baseline pressure to operate properly.

Let’s walk through a sample scenario to see how the XLS should work.

, which is the total pressure the pump must generate to overcome gravity and friction.
