I am trying to determine how long I need to run my pump to get 1 turn-over per day.
I have a WhisperFlow WFDS-6 dual speed 1 1/2 hp pump and 19,000 gallon pool. There is a chart on the last page of this document www.poolsuppliestoday.com/pdf/pent_whisperflo.pdf but I don't understand how to read it. If I follow the curve for the WFDS-6 it looks like it pumps a little over 80 gpm at 3450 RPM and about 130 GPM at 1750 RPM. This does not make sense to me as I can visually see more water being moved at the higher rate. Like I said - I don't know how to read this chart so I am misinterpreting the data.
I need to run the pump on high speed for a while to operate the hayward sweep (POS) and then I want to run on low speed until I get the turn-over. Any suggestions? BTW, I have it set for 1.5 hours on high and 2.5 on low, at the moment.
