    Hayward SuperPump Motor replacement

    I'm thinking about replacing my 1 Hp super pump single speed motor with a dual speed . The existing motor is A.O Smith Model C48K2N143B1 .
    115/230 volt. frame is 56J. It is developing an intermittent bearing squeal and I'd like to save some money on electric costs at the same time.
    Is there a replacement motor that is generally accepted as the best option? What manufacturer/Model number should I get?

    Thanks for any suggestions.

    The Century B2975 or B2975T (integrated timer) would be just the ticket for your pump. If you dont have automation the T version will be a direct bolt on without changing anything or running wires. The non T version would require appropriate switches / timers.

    Re: Hayward SuperPump Motor replacement

    The B2975 is a larger diameter than the motor that comes with the SuperPump. Some SuperPump motor supports have a removable piece so the larger motor will work, some don't. You might want to check first before purchasing the motor.

    However, if you want to avoid the issue, the STS1072RV1 is the same size as your current motor.

    Also, if you decide to go with the larger motor the B2973 is a better fit for the 1 HP SuperPump.

    Re: Hayward SuperPump Motor replacement

    The dual speed option is going to save you the most money on operational costs and the new dual speed motors with integrated digital timers are really nice. If you did end up staying with a single speed motor than the UCT1102 is the energy efficient version of the C48K2N143B1 and will save you roughly 20% on your operational costs.

    When you replace your motor you will always want to replace your pumps shaft seal as if you use the old sealy many times you will have leaking and this would not be covered under the manufactures warranty. Typically the best bet is to get a Tune Up Kit which includes the shaft seal and all the o-rings and gaskets for your pump as well as lubricant, the gokit for the Hayward Super Pump is GOKIT3.

    Mark - good catch on the physical size issue with the super pump. I always forget that about the super pump.

    I was suggesting the B2xxx because of the availability of an integrated timer. I think either the B2973 (3/4 horse 1.5SF total HP 1.12) or the B2975 (1hp, 1.25 SF total HP 1.25) will be fine if Franks pump has the knockout. The deciding factor should probably be whether the current pump is wired 115V (B2973) or 230v (B2975).

    The STS1072RV1 is 2.2 amps at 230 vs 1.5 amps for the B2975 at 230 vs 2.2 at 115 (equivalent of 1.1 at 230) for the B2973. making the STS1072RV1 most expensive to run and the B2973 cheapest to run.

    Frank - looks like you have some homework to do.

    IMHO - if your superpump has the knockout for the motor the B series are the way to go. If not Mark nailed it with the STS1072RV1. If you do have the knock out you need to determine if your pump is hooked up 115 or 230. @115 go with the B2973 (or B2973T) @230 go with the B2975 (or B2975T)

    my pump is wired for 230v . I'm not sure what the knock out for the bigger diameter motor looks like. I was really liking the integrated timer option on the b2975t.

    Not true! You are quoting motor ratings which are not the same as operating points. The amp ratings on a motor label set the maximum allowed current level only, not what the motor will actually draw. This is especially true on low speed.The RPM and the impeller dimensions set the load on the motor and since all of these motors are standard efficiency motors, they should all draw about the same power within a few watts.

    Re: Hayward SuperPump Motor replacement

    If you look at the diagram:

    http://www.hayward-pool.com/pdf/Part...Super-Pump.pdf

    There is a curved part at the back of the mounting foot (part 9). On some feet it is removeable to accommodate the larger motor. On others it requires a little dremel work. See the thread below for a description of the dremel work

    I was under the impression that the "low speed" amp rating I quoted were functionally what the motor operated at when on low. Hmmm. Time to break out the VOM and see what my B2984 operates at on low.

    Re: Hayward SuperPump Motor replacement

    A VOM will give you an incorrect answer. Amps * Voltage is not real power in an induction motor, especially at low speed. You need to take into account power factor so you need a power meter or a scope to measure the phase difference between voltage and current.

    One more thing, power factor plays into the rating in the motor. You can have two motors on the same pump that draw different current but yet still have the same power draw because the power factor is different for each motor.

    My plan was to measure the amp draw on each leg at the panel. Am I missing part of the equation (we should probably split this off into the deep end....)?

    Long and short I agree with you on the functional cost of running the motor ... should be just about identical given the same size impeller (which all 3 are more than capable of turning) as the load will be identical. Just finished cup of coffee #2.

    Re: Hayward SuperPump Motor replacement

    Yes, you are ignoring power factor. This is the phase difference between the voltage and current and splits the power into real and reactive parts. You are charged by the real component of the power only. You can read about it here:

    Excellent!

    I love it when I learn something new. Thank you, I'll give it a long read this afternoon.

    Ok so the STS1072RV1 and a timer if your foot doesn't have the knockout and you aren't comfortable with the dremel.

    OR

    B2975T

    Mark,
    Agreed?

    Re: Hayward SuperPump Motor replacement

    It looks like i do not have a removable "knock out" Would it be a good idea to replace the base plate with this?http://www.inyopools.com/Products/07...tm#description
    or would dremel work be better? i am still leaning towards the b2975t

    Re: Hayward SuperPump Motor replacement

    I'm going to have to leave that one to someone with superpump experience.

    I cant get the inyopool site to come up...

    Thinking you were linking to something like this http://www.poolsupplyworld.com/Haywa.../SPX2600G1.htm
    with the interchangeable support, looks like a good idea ... but again, no experience with super pumps from me.

    Re: Hayward SuperPump Motor replacement

    Just An update..
    I bought the b2975T dual speed motor with timer , the mounting foot p/n SPX2600G1 and the GOKit-3
    Everything went together smoothly and the pump is now running perfectly.
    Thanks Everyone for the help!
