| (CAST IRON WITH BRONZE IMPELLER PUMPS.) C.R.I. 8" Evergreen Series Submersible pumps are available with different materials of construction. Pumps are incorporated with extremely hardwearing bearings and built in stainless steel check valve. All vital components of these pumps are designed for the best possible hydraulic efficiency. All the bronze components are made of high grade "Bronze" to resist corrosion and to with stand wear & tear caused by sand. Also the high quality cast iron components and shaft made of S.S.431 ensures the long life of the Pump. Pumps are multistage centrifugal type, which are firmly coupled to a submersible electric motor which operates submerged beneath the surface of water. Built in check valve prevents back flow and reduces the risk of water hammering. C.R.I. Submersible pumps can be offered with either C.R.I. 'W' Series water filled rewindable submersible motors or any other NEMA Standard motors. C.R.I. 'W' SERIES SUBMERSIBLE MOTORS These motors are eco-friendly wet type, water filled and rewindable. The stator windings are of waterproof synthetic film insulated copper winding wires. It features water lubricated thrust and journal bearings. Motor is pre filled with clear, cold, pure, fresh, filtered water. However, on request, motors can be pre filled with water and propylene glycol (Anti freeze agent) for places where the temperature is below the freezing conditions. Before commissioning, ensure the pre filled level of water inside the motor. If any loss of volume is noticed, refill with clear, cold, pure, fresh, filtered water, through water filling plugs provided in the upper housing. Should the use of anti-freeze agent mixed water not be allowed for special applications, these motors can also be filled with clear, cold, pure, fresh, filtered water and operated. Mounting dimensions of pumps and motors are in accordance with NEMA standards.
