These 8" encapsulated motors, manufactured in ISO 9001 certified facilities, are built for dependable operation in 8" diameter or larger water wells with ambient temperatures up to 75 °C.
It is fitted with water lubricated radial and thrust bearings for maintenance-free operation. The motor is filled with a special FES92 fluid, providing frost protection down to -15 °C storage temperature.
A special diaphragm ensures pressure compensation inside the motor. The Sandfighter® SiC seal system is standard.
