6” Water Lubricated C.I. Klassic Motors (50/60 Hz)

Unnati UW6 series submersible motors are water Lubricated designed for installation in 6″ diameter or larger water wells. These motors can be easily rewound and repaired. Unnati Submersible Motors are robustly rewindable and pre-filled with clean water mixed with anti-corrosion fluid. The stator winding is of PVC or Poly Propylene insulated copper winding wires. It features water lubricated radial and thrust bearings. The dynamically balanced rotors of these Unnati UW6 Series submersible motors maintain uniform clearance to give better efficiency and increase the life cycle of the water-lubricated bush bearings. Specially designed high-performance thrust bearings are used to withstand high axial thrust loads.
