Types: 3 Phase Encapsulated & Encapsulated Motors

6″ Encapsulated Motors are manufactured in ISO 9001 certified facilities and are built for dependable operation in 6″ diameter or larger water wells. Water lubricated thrust and radial bearings enable a maintenance free operation : the motor is filled with a special FES91 fluid, providing frost protection down to -15 °C storage temperature and a special diaphragm ensures pressure compensation inside the motor. The Sand fighter® SiC seal system is standard.
