4 in Encapsulated Motors

4-Inch 3-Wire Motors

Franklin Electric 4-inch encapsulated 3-wire capacitor single phase Motors, manufactured in ISO 9001 certified facilities,are built for dependable operation in 4-inch diameter or larger water wells. Together with the Franklin Electric Control Boxes, they offers you a maintenance free long life operation by high starting torque and included motor protection. The motor is filled with a special FES93 fluid, providing frost protection down to -40 ºC storage temperture. A special diaphragm ensures pressure compensation inside the motor.
