    Pump Question

    I came home the other day and noticed the pool pump was off. The pump is a 1 HP Centurion. I checked all the switches and electrical...everything was okay. I started to take apart to pump to check if the impeller was moveable, but when I touched the motor it was HOTTER than **** (hot enough that when water dripped on it steam rose). Anyways, the impeller does not move. I assume the motor is seized...is this correct?
    Also, if I were to buy a new pump, do I need to get the same HP, voltage, etc.?

    Re: Pump Question

    Centurion is the name of the motor, not the pump. I know, they should put the name on the pump.

    If you can read the nameplate of the motor you can probably just replace the motor. You need to match the SFHP (service factor x Horsepower) the frame size and the voltage. I.E. if you have a 1 hp motor with a service factor of 1.15 you have 1.15 SFHP. So if you found a 3/4 hp with a service factor of 1.5, it would work.

    I'd suggest looking at 2-speed motors while you're looking.

    So you have a 1.65 (1HP*1.65SF) SFHP. That is what you want to match for high speed.

    I think B2982 is the 2 speed version of the motor.

    Note here that most 2 speed motors are 240V only, where the single speed you have is 120 or 240V, so if you plan to switch to a 2 speed you need to make sure yours is currently wired 240V, or you need to make provisions to have 240V ran to the pump.
