How does a variable speed pool pump work?

Similarly, how long should you run a variable speed pool pump?
(This flow rate is, on average, the middle speed on a variable-speed pump or the lowest speed of a 2-speed pump.) Using this formula, the filter should run for about 7 hours per day for one full circulation.
Secondly, how does variable speed pump work? 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. 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.
Subsequently, one may also ask, do variable speed pool pumps really save money?
Typically, pool owners who switch to variable-speed pumps recover the cost of the pump in energy savings in less than two years. You could save up to 83 percent in annual energy costs (give or take, depending on where you live and other variables) just by upgrading your pool pump.
Why is a variable speed pool pump better?
With a variable speed pump a pool owner can circulate their water at lower flow rates for a more prolonged period of the day without added energy consumption. This study by the National Renewable Energy Laboratory confirms that variable speed pumps are significantly more energy efficient than single speed pumps.
