    Question Challenger motor replacement

    I'm replacing the motor on my Challenger CF-NI-2A High Flow pump, because it is tripping the GFCI breaker, 15 years old, and single speed. Photos below of current pump and motor.

    Before ordering the motor, I need to verify that I selected the correct motor. After looking at so much data over the past three days, my mind is overloaded. Best to let the group on this site check my work. Thanks for helping me out.

    Existing Motor: Centurion for PAC-FAB
    -2hp Uprated
    -SF: 1.1
    -SFHP 2.2
    -Single Speed

    Replacement Motor: Century B2983
    -1-1/2 or 0.19 hp Full Rated
    -SF: 1.47
    -SFHP: 2.21
    -Dual Speed
