    Replacing SuperFlo 1 speed motor w/ 2 speed

    I would like to replace the motor on my SuperFlo 1.5 HP single speed (340039) with a 2 speed motor.

    Is the Pentair 356630S motor the correct motor?
    Do I use the same impeller?
    Which gaskets should I replace when I perform the swap?

    Thank you for any help.

    You could get a Pentair motor but it would probably cost you a lot more. The B2982 motor is direct replacement as well.

    Yes, you can keep the same impeller unless you want to downsize the pump.
