I am trying to figure out if about 900 to 1000 RPM is really the best RPM range for maximum efficiency in terms of gallons pumped per kwh of electricity for an Intelliflo pump. I tried to gather some data from my system and got about 35 GPM (calculated from XLS spreadsheet) for 800 RPM and 116 watts. I also got 128 watts for 450 RPM which does not seem to be accurate. The calculated value makes no sense from the xls table on an old post on this site. Anyway, does anyone have gallons pumped per kilowatt hour for flow rates in the range of 450 RPM to about 1200 RPM? This is really just for to satisfy my curiosity, so its not a big deal.. My pool is about 25000 gallons. Thanks.
