    Hayward Super II Pump Replacement

    The bearings on my motor are going south so I need to replace the motor. i'm having a hard time finding the correct replacement motor online. I have looked at electric motor warehouse and inyopools.com.

    It appears my motor is a two speed but there is no switch to choose high or low speed so i assume it runs only in high speed. From the label I don't know what HP it is either since the label says 2.5-.42.

    My pool set up is:
    14,500 gallons
    Chlorine
    Plaster
    Spa
    Polaris 360
    Cartridge filter

    Any suggestions on what pump to get? I was thinking the 1.5 HP energy efficient model but I'm not 100% sure and don't want to order the wrong motor.

    That is a 2.5 HP Uprated two speed motor. You can use a Century B979 as a replacement:

    I would definitely stick with a 2-speed motor and make it so you can run on low speed to save yourself some money on electricity.

    Is there any reason you need such a large motor? water features / spa?

    If not, get a smaller 2-speed motor with a matching impeller. You can not go to a smaller motor without also replacing the impeller (which should only be around $25)

    Must be the tryptophan still in the blood stream.

    With a spa and a single pump, I would not lower the pump HP.

    Ah, skipped right over that ... and did not see it in the signature

    Still felt the need to point out that getting a smaller motor should not be done without a smaller impeller ... although as Mark says, with the spa you should not likely go smaller and thus should just get one of the motor he linked to.

    You will also need a new shaft seal.

    So a two speed 2.5 hp with new seals should do the trick? Why do you need the higher HP with a spa? The only time the spa runs alone is when it's being heated.

    Normally, spa jets require high flow rates for strong jets so the pump has to be large to support them. Unless of course you have a separate jet pump. Then you wouldn't need such a large pump for just circulation.
