Hi,
I think it has actually come down to me ordering a dual speed 2hp Whisperflo pump. I want to see if anyone can confirm the following for me though. Pulling postings with GPM's from many people I have concluded the following:
based on my usage, I am approximating the following GPM's needed for:
solar 7 4x16panels, 30ft up on roof.....30-40GPM
jets in step-n-spa (NOT a separate spa) 3 jets 45gpm
regular filtering of pool 33gpm/10hour turnover rate (19,600gallons)
Pentair QuadDE80 filter (??gpm, but I am sure it will fit into the scheme of things)
My question is the dual speeds operate at 1750 RPM for low and 3450RPM for high does anyone know the GPM's for these speeds?
I know KTDave had provided the following information regarding his VS3050 pump, but not sure if the RPM and GPM apply the same for a dual speed pump. If this compares apples to oranges, can someone provide to me with estimated GPM ofr the two speeds on a dual pump.....please.
To me, it does not seem the VS3050 would be worth the extra money since all of my applications need to operate at the about the same RPM. If this is the case, I also feel I would not need an automatic control unit either.
Thanks again!
KTDave provided the following:
The lowest reading on the flow meter is 15 GPM (highest is 70).
RPM - GPM
1370 - 15
1500 - 24 (default speed 2)
1600 - 28
1700 - 33
1800 - 37
1900 - 41
2000 - 46
2300 - 57
2350 - 60 (default speed 3)
2500 - 65
