6″ Rewindable Submersible Motor

These 6″ 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 ºC storage temperature. The Sandfighter® SiC seal system is the option for sandy applications. For applications in aggressive media, motors made of 316SS and 904L are available.

Specifications:

  • Cable material according to drinking water regulations (KTW approved)
  • Sand slinger and mechanical seal for high performance in sand
  • High efficiency electrical design for low operation cost
  • All motors prefilled and 100 % tested
  • Max. storage temperature -15 °C – + 60 °C
  • Design for retrofitable PT100 sensor
