Pentair 355705S / 353319S Challenger 5 HP Pump Motor 56Y Frame 208-230V

The Pentair 353319S Pool Pump Motor is a factory original replacement for the Pentair 355705 Challenger 5 HP Pump Motor. This is a Square Flange style motor with a 56Y Frame and is a High Efficiency 5 Horsepower Motor. Square Flange motors have a square "face" where the motor mounts to the pump with 4 non-threaded bolt holes to attach the pump and a threaded shaft.

It is important to know that not all pool pump motors are not manufactured by the pump manufacturer; the motor will usually be manufactured by AO Smith, Magnetek or Centurion. Your pump's motor should have a label or faceplate on it which includes the information you need to replace your pump motor. The most important categories to note will be the horsepower (hp), motor frame (fr), voltage and service factor (sf). Some labels will provide you with a model number and it will usually be listed as CR or CAT.

When replacing your pool pump motor you should always replace the shaft seal as well. The shaft seal is a 2 part piece made of rubber, metal and ceramic and keeps water from entering the pump motor. It is located near the impeller at the end of the motor shaft. Shaft seals vary between pumps so be sure to order the appropriate shaft seal for your pump.
