The unit comes with an intuitive interface that displays watts and RPMs, so that you know at all times just how much power the pump is drawing and how hard it works. A great choice for people that want to spend less on their power bill and protect the environment. What’s more, this unit is an Eco Select Brand product which means that it is Pentair’s greenest and most efficient choice. This feature means that the pump is adaptable to all types of electrical installations that are commonly found in the US. The nominal voltage range is 110V through 230V. This is the only variable speed pump on the market with 115/208-230V and 50/60Hz single phase capabilities. The only difference is that for larger pools it will take longer to get the job done, while for the smaller ones it will be faster. The 1.5 horsepower motor allows the unit to work best with pools of around 20,000 gallons, but it can also handle smaller or larger basins. The manufacturer specifies that this unit has three main speeds that it can work under, but since this is a variable option, you will be able to set it to whichever speed you like so that you can save on energy and get the job done in an efficient manner. This will mean that sudden changes in flow or pressure are less likely to occur. Because variable speed pumps run at speeds that are below their maximum power, they will use less energy and there will be a reduction in wear, especially for the mechanical seals.Ī variable speed pump controller can also monitor small variations in pressure and make the needed adjustments. The VS in the product’s name stands for variable speed and this is a great feature for an energy-efficient pool pump to have.
