8 Inch Water Filled Stainless Steel Motor




These motors are heavy duty, rewindable, stainless steel water filled submersible motors which are designed and sized for installation in 8” diameter or larger water wells. They are of robust construction and are furnished with heavy duty radial & thrust bearings to take the extra radial & thrust load when used with high head pump.

Product Features :

  • 8” Water filled stainless steel submersible motors.
  • Easily rewindable (wet wound) induction motor with PE insulated windings.
  • Completely stainless steel AISI 304 construction.
  • Water lubricated radial and axial thrust bearings.
  • Counter thrust bearing.
  • Motors are pre-filled with clean water + Glycol mixture.
  • Shaft extension made of stainless steel AISI 316.
  • High efficiency electrical design (lower operating cost).
  • Tropicalized design (lower winding temperature).
  • 8” NEMA coupling flange.
  • Pressure compensation diaphragm.
