I have to replace an older 2 hp single speed Super Flo pump that's shot and I have a question regarding the viability of a VSP. I have a 42,000 gallon pool with 2" piping and an estimated TDH of 55. I have an attached spillover spa that has a separate pump for jets and a Polaris 280 with it's own booster.
Looking at various VSPs, it appears I would need to run the pump at higher rpms for 10 or 12 hours (70 gpm or 58 gpm respectively plus or minus) to get 1 turn over. With the single speed, the rpms are similar, and my Aqualink shuts the pump down for about 9 hours overnight.
Am I looking at this the wrong way or is the benefit of a VSP not as great in my situation? Based on various flow charts considering the TDH, I would probably need something around 3 hp that would run for hours like the 2 hp single speed. I need some help on this.
Thanks in advance all.
