May need to replace my 3/4hp Super Pump (Hayward). I know its equivalent is the Superflo on the Pentair side, but was looking at the Whisperflo too. Interestingly, looking at the GPM curves, the 1/2hp Whisperflo gets better GPM than the 3/4hp Super Pump. For example, at 30 head feet of water, the Super Pump moves about 55gpm while the Whisperflo moves (what looks like) about 75gpm, based on the charts linked to below.
Am I reading this right? I could save quite a bit of power by going with the Whisperflo. Conventional wisdom is that a 1/2hp pump is too weak for my pool (24k gal in ground) but hey, they charts don't lie! Or do they
