Αναπαριελίξιμοι υποβρύχιοι κινητήρες 10”

These 10" rewindable motors, manufactured in ISO 9001 certified facilities, are built for dependable operation in 8" 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 and 904L are available.
