6" Rewindable
Submersible Motors
4 Kw through to 37 Kw, 3 Phase
380-415 Volts; 50 Hertz
These 6 inch rewindable motors, manufactured in ISO 9001 certified facilities are built for dependable operation in 6" diameter or larger water wells. Water lubricated thrust and radial bearings enable a maintenance free operation.
A special diaphragm ensures pressure compensation inside the motor. The motor is filled with a special FES93 fluid, providing frost protection down to -15°C storage temperature.
The SAND FIGHTER™ SiC seal system is the standard option for applications in aggressive media, motors made of 316 SS and 904L are available.
