Save Money, With This Inverter Variable Speed Mod to Your Pool Pump: There are commercially available units which use an VFD inverter to vary the speed of your pool pump, and although they provide great savings, being a DIY-er i wanted to have a go on my own, and try and simplify the whole unit. A variable-frequency drive is a device used in a drive system consisting of the following three main sub-systems: AC motor, main drive controller assembly, and drive/operator interface. Example: A VFD controlling a pump motor that usually runs less than full speed can substantially reduce energy consumption over a motor running at constant speed for the same period. Personally, I would allow the VFD to control the motor above a certain tank level or inflow rate. In this case, the pump impeller size may need to be reducedto increase the speed of the motor rotation to get adequate cooling. Because the drive controls the speed of the motor directly based on actual demand, a more efficient match to the actual system requirements is more easily achieved, increased energy savings are possible, and stress on the pumping Introduction The Aquavar® CPC (Centrifugal Pump Controller) from CentriPro incorporates the latest state-of-the-art Aquavar technology, with over 10 years of experience providing variable speed pump controllers.
