200 mm (8″) Borewell Submersible pumpsets are powered by water filled, rewindable
submersible motor which is suitable for continuous duty. The stator is wound with special
waterproof synthetic film insulated copper winding wires and made up of low watt loss
silicon steel laminations assembled under pressure and rigidly locked in stainless steel stator shell.
Specially designed thrust bearings (SS AISI – 420 with Graphite carbon) are used
to withstand axial and down thrust loads with minimum wear and tear.
