Pool and Spa Pump / Motor Replacement Guide for Square Flange and C-Flange Motors

For Square Flange and C-Flange Motors

Pool motors and pumps need to be properly matched to one another to provide consistent, predictable performance. When selecting your US MotorsĀ® brand replacement pool motor, you will need to know six important pieces of information.

  1. Pump Mounting (i.e. square flange, c-flange, etc.)
  2. Horsepower (HP)
  3. Service Factor (SF)
  4. Voltage
  5. Frequency
  6. Phase

Most of this information can be attained from the pool motor nameplate. Always be sure that the total of horsepower times service factor of your new US Motors brand pool motor is equal to or greater than the total of horsepower times service factor of the original pool motor.

Total Output HP = (horsepower) X (service factor) = THP or SFHP
