6″ Encapsulated 3 Phase HiTemp 90°C Motors – Franklin Electric

Franklin Electric 6″ encapsulated motors, manufactured in ISO 9001 certified facilities, are built for dependable operation in 6″ diameter or larger water wells with ambient temperature up to 90 °C.

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 FES92 fluid, providing frost protection down to -15 °C storage temperature.

The Sandfighter® SiC seal system is standard.

  • Hermetically sealed encapsulated stator, anti track, self healing stator resin
  • Removable “Water Bloc” lead connector
  • Sandfighter® motor with SiC-mechanical seal
  • High efficiency electrical design for low operation cost
  • All motors prefilled and 100 % tested. Max. storage temperature -15 °C – + 60 °C
  • High temperature leads
  • Non contaminating FES92 -filled design
