    Replacement Circulation Pump Motor Advice


    My 3/4 HP Hayward Northstar circulation pump motor has gone kaput. I've researched variable speed, single speed, and 2 speed replacement options but have only succeeded in becoming confused. Have no real preference for either type. Looking for overall most cost effective solution. Hoping that the experts on this forum can help lead the way. Here are the stats:

    - 19,000 gal IG plaster w/connected spa overflowing to pool
    - separate jet pump for spa
    - separate pump for roof mounted solar
    - Hayward Navigator suction side pool cleaner
    - all 2" plumbing at equipment pad
    - 325 sf cartridge filter
    - 220V wiring
    - Jandy RS4 controller (vintage 2003/2004, don't think it operates VS or 2 speed pumps)
    - average cost/KWh = $0.19
    - utility company rebate of $100 available for VS pump

    Any advice would be much appreciated. Thanks!

    I would go 2 speed and put a high low switch on the pump.

    Which 2 speed motors are you looking at?
