When your pool pump is turned on it pulls water from the main drains and skimmer. The vfd controller will be set so that it keeps the outlet pressure of the pump constant no matter what flow is required out of the pump.

Using a variable speed pump can cut associated energy costs up to 90.

At 862 5 rpm s the motor is using only a scant 17 5 watts. Here s a quick summary of the process.
