4″ Resin Filled Encapsulated Submersible Motors
C.R.I. "R series" motors are deep well / bore hole encapsulated submersible type, pre filled with anti-freeze agent as coolant and lubricant. These motors are available in single phase and three phase power supply. All single phase motors are thermally protected and specific ranges are in-built with lightening arrester. Rotors are supported with bush and thrust bearings to withstand maximum axial and radial thrust loads. All mounting dimensions are in accordance with NEMA standards.
