Franklin Electric E-tech 12-inch rewindable motors, manufactured in ISO 9001 certified facilities, are built for dependable operation in 12-inch 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 temperture.
A special diaphragm ensures pressure compensation inside the motor.
The Sand fighter® SiC seal system is standard. For applications in aggressive media, motors made of 316SS are available.
