6 inch Motors

8-Inch Encapsulated Motors

These 8-inch encapsulated motors, manufactured in ISO 9001 certified facilities, are built for dependable operation in 8-inch diameter or larger water wells. It is fitted with water lubricated radial and thrust bearings for maintenance-free operation. A special diaphragm ensures pressure compensation inside the motor. The motor is filled with a special FES91 fluid, providing frost protection down to -15 ºC storage temperture. The Sand fighter® SiC seal system is the option for sandy application
