Duke’s DSM8 – Series Water Filled motors are Re-windable wet type water cooled Submersible motors designed to drive Duke’s or any NEMA standard submersible pumps. They are available in 8″  size as standard supply and beyond that against requirement. The windings are made up EC grade copper conductor and insulation & sheath material of excellent electrical and water-proof property. High performance specially designed water lubricated thrust bearings are provided to withstand high axial thrust loads exerted by whole bore well water column and pumping systems. These motors are available in different types of MoCs like Fully Stainless Steel or Cast Iron constructions. The mounting dimensions are as per NEMA Standards and keyway type motors can also be supplied as per against requirements.
