Franklin Electric 6″ encapsulated motors, manufactured in ISO 9001 certified facilities, are built for dependable operation in 6″ 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 °C storage temperature.
The Sandfighter® SiC seal system is standard.
