4-Inch Encapsulated PSC Motors

4-Inch 1-Phase PSC Motors

Franklin Electric 4-inch Submersible Encapsulated Motors, manufactured in ISO 9001 certified facilities. This motors are built for operation in 4-inch diameter or larger water wells. It is fitted with water lubricated radial and thrust bearings for maintenance-free operation. The motor is filled with a special FES93 fluid, providing frost protection down to -40 ºC storage temperature. A special diaphragm ensures pressure compensation inside the motor. The PSC motor is a single phase motor for operation with run capacitor. Capacitor and motor overload protection have to be provided by the customer. The motor is connected to only one capacitor which works permanently as start and run capacitor.
