I tried so hard to figure out my application without having to ask, especially as a first time poster. There is so much great information on here. Unfortunately I hit a dead end in my research and I really do need some help.
My pool is over an over 20 years old in-ground and I have to replace filter and pump. My wife wants chlorine generator.
I'm in SW Georgia. I mostly get tree flowers pine straw and a ton of green algae as my worst problems.
The pool is a liner, 16 x 36 rectangle with 9 1/2 deep and 3 1/2 shallow. I calculated at 28,000 gallons.
I have no heater, spa, waterfall or solar.
It is a basic set up with the closest end containing the bottom drain and two basket returns at about 20 ft. There are two returns at the opposite end.
I have 1 1/2 inch pipes and I think 2 inch at the pad.
The pump is about 4 feet lower than the pool.
I have a Polaris with a booster pump.
I did my calculations and came up with an approximate 55 gal/min minimum. The maximum I came up with was about 85 gal/min.
Head pressure calculation (guesstimate) of about 55-60.
I'm looking to change from an old foxx sand filter to a ~520 (Pentair or Jandy) cartridge filter (I never want to clean the filters :-D ) I looked into the sand filter a couple months ago and I had plants growing in the sand???
My question is in regards to the pump replacement. Here is what I found for the pumps:
Pentair Whisperflo WFDS-3 3/4 hp 2 speed 7.8A/3.0A
Pentair Whisperflo WFDS-24 1 hp 2 speed 7.8A/3.0A
Pentair Superflo 1 1/2 hp 2 speed 7.8A/3.0A
Sta-Rite SuperMax 1 1/2 hp 2 speed 7.8A/3.0A
Jandy Stealth SHPF 1.0 2 speed 7.2A/3.0A
Jandy Stealth SHPM 1.5 2 speed 7.2A/3.0A
Jandy FloPro 1.5 hp 2 speed 8A/3.0A
From these two companies, the pumps seem about equal? I just cant seem to find information from these two companies that explains the differences in their pumps and describes the pros and cons. It seems all of these pumps are in the same price range, but what makes one better or different than the other? I have read opinions about which brand is better, but not too much as far as objective descriptions of the differences. I'm looking for the most efficient, the quietest, the best built pump and ultimately the best value pump for my application. Information that would be helpful from the manufacturers would be pump design, quality of steel and bearings, how they handle heat dissipation, motor efficiency etc. They don't explain how set-up has alot to do with noise, and I found that out reading this forum. I understand that buying a product from a dealer you trust may be as important as the manufacturer of the product. That is unless it is not. I just hate buying relatively expensive products this way.
Also, why produce the same pump/motor but label it with 2 different horsepowers? For the Stealth and whisperflo above, are each of the two pumps exactly the same????
