All Products >> Agriculture & Residential Pumps >>200 mm (8 inch) Borewell Submersible Pumps – BHIMA Series
  •  

    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.
