Variable Speed Pool Pump How It Works

When you run the pump at lower speeds that means you re using less kw or energy from your power company.

Variable speed pool pump how it works.

If you had a flow meter you just dial it in to 9 gpm and set that as your base operating speed. When your pool pump is turned on it pulls water from the main drains and skimmer. For spa lovers jets can be tuned to the exact massage flow desired adjusting for all the individuals in your household. This is why a proper variable speed pool pump schedule includes periods of time where the pump will run higher than the minimum rpm values.

With a variable speed pump a pressure sensor is mounted on the outlet of the pump and this measures the operating pressure of the pump. A pool pump that uses 1119 watts per hour at 3450 rpm single speed pump rpm s will use only 140 watts at 1725 rpm. Using a variable speed pump can cut associated energy costs up to 90. A variable speed pool pump will allow you to reduce the flow reducing the sound your features make.

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. At the core variable speed pool pumps work just like regular pumps aside from the speed options. A 2 pvc pipe can move around 80 gpm total. Most variable speed pool pumps go as low as 500 to 600 rpm s so you can really see how this can reduce on the electricity that you use.

At 862 5 rpm s the motor is using only a scant 17 5 watts.
