These 6-inch encapsulated motors, manufactured in ISO 9001 certified facilities, are built for dependable operation in 6-inch diameter or larger water wells with ambient temperature up to 90 °C. Water lubricated thrust and radial bearings enable a maintenance free operation. A special diaphragm ensures pressure compensation inside the motor.
The motor is filled with a special FES92 fluid, providing frost protection down to -15 ºC storage temperature. -
