Our pool was built in the summer of 2000. The first two-speed motor lasted until September 2008. The existing two-speed motor, which is still running ok, was installed at that time. So the existing motor is 8 years old. I decided to try something new and wise, which is to do my new motor research in advance instead of after my current motor fails. Here are the specs for our pool:
location: Phoenix area
15,900 gallons
2" return lines, 2.5" suction lines (both about 50 foot runs)
in-floor cleaning system (MagnaSweep by A & A Manufacturing, 6 zones, 27 heads)
in-deck chlorinator
no water features and no spa
WhisperFlo pump WFE-28
Purex cartridge filter system (405 sq. ft.)
A.O. Smith 2-speed motor, 2 hp high, .33 hp low (not sure of low speed hp as label is no longer readable)
Cost for power: about 11 cents per kw
My wife insists that the pump be run 24/7 during our warm season (May-Oct) as she takes care of the chemicals and she loves a spotless pool. We are set for 22 hours on low and 2 hours on high. So factor that non-negotiable issue into any motor recommendations. I might be able to sell her on reducing the high run time to one hour. The original electrician wired in two Intermatic mechanical timers in a side-by-side configuration that allows us to use the timers to automate the the low speed and high speed run times of the two-speed motor.
Since the pump body seems to be doing its job, I hope we can just go with a new motor only, unless there is some compelling reason to upgrade both pump body and motor that I am not aware of.
Given all of these parameters, does anybody have any thoughts on what would be good options as a replacement motor once our existing motor dies?
Should we go two-speed again or would we see benefit in a VS?
