Eco Solar installs variable speed pumps exclusively. The first variable speed pump we installed in 2007 was the Ikeric pump and it is still running properly in February 2016. We are certified on most major VS pump types, but find the Pentair Intelliflo and Intelliflo XF pumps to be our favorites.
We are a company supply single speed pool pump, San Ramon variable speed pool pumps, variable speed pumps lafayette, pentair intelliflo variable speed pumps etc. This pump efficiency chart shows the difference between a standard induction single speed pool pump and the Intelliflo variable speed pump. The Intelliflo maintains about 90% efficiency throughout the motors load spectrum. There are hundreds of speed set choices that can be input in its easy setup menu so you can maximize its efficiency for each function in your pool, spa or solar heater. I can program the Intelliflo pumps in less than 2 minutes, setting time, schedules, 4 speeds, low and high-speed limits and a few other inputs. A single speed pool pump has a maximum motor efficiency of only 65% at one spot of its performance curve, and it rarely operates at that best load. Why? Because its only operating speed is a full blast at 3,450 rpms.
And look at what happens to a 2-speed standard induction motor goes to low speed. It does so by lowering the voltage to the motor. When the voltage lowers, the amperage goes up and chokes the motor efficiency dramatically. In this example, a 2-speed motor can only achieve 20% efficiency or 80 percent waste.
