High-temperature motor

asynchronousACvertical

These 8" encapsulated motors, manufactured in ISO 9001 certified facilities, are built for dependable operation in 8" diameter or larger water wells with ambient temperatures up to 75 °C. It is fitted with water lubricated radial and thrust bearings for maintenance-free operation. The motor is filled with a special FES92 fluid, providing frost protection down to -15 °C storage temperature. A special diaphragm ensures pressure compensation inside the motor. The Sandfighter® SiC seal system is standard. ■ Increast thrust capacity up to 30 °C ■ No cooling flow in larger wells (open reservoirs) up to 30 °C ambient ■ Hermetically sealed encapsulated stator ■ Removable Water Bloc lead connector ■Sand fighter® Motor with SiC-Mechanical Seal ■ High efficiency electrical design for low operation cost ■ All motors prefilled and 100 % tested.
