12″ Rewindable Submersible Motor

These 12″ rewindable motors, manufactured in ISO 9001 certified facilities, are built for dependable operation in 12″ diameter or larger water wells. It is fitted with water lubricated radial and thrust bearings for maintenance-free operation. The motor is filled with a special FES93 fluid, providing frost protection down to -15 ºC storage temperature. A special diaphragm ensures pressure compensation inside the motor. The Sandfighter® SiC seal system is standard. For applications in aggressive media, motors made of 316SS are available.
