Franklin Electric 6″ rewindable motors, manufactured in ISO 9001 certified facilities, are built for dependable operation in 6″ diameter or larger water wells.
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 FES93 fluid, providing frost protection down to -15 ºC storage temperature.
The Sandfighter® SiC seal system is the option for sandy applications. For applications in aggressive media, motors made of 316SS and 904L are available.
