Pool Pump Replacement Motors
Pool pump motor replacement is a common practice among pool owners. The most common reasons that a motor would need to be replaced include failed bearings, corrosion inside and/or outside the motor, failed start and run capacitors, and motor age. When replacing a pool motor, you will need to keep in mind the frame type, horsepower, whether it’s up-rated or full-rated. We also recommend replacing the shaft seal when installing a new motor.
Single Speed and Dual Speed Motors
Single Speed and Dual Speed Motors have man-made magnets that slowly draw more amps over the life of the motor due to a loss in polarity. They also utilize non-sealed front and rear bearings making them more susceptible to water damage. Single-speed and dual-speed motors are air-cooled, requiring adequate space around the motor for cooling.
