C.R.I. PUMPS DEEP WELL SUBMERSIBLE PUMPS EVERGREEN SERIES - 5Hz An ISO 91 & 141 Company
Submersible Pumps C.R.I. Submersible Pumps are the products of the expertise gained from over four decades of experience, endurance and workmanship. These products are engineered to perfection with utmost care and stringent quality control at all stages to ensure a trouble free service. Description : C.R.I. 6" & 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 "Zinc free bronze" to resist corrosion and to withstand 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. All mounting dimensions of pumps & motors are accordance with NEMA standard. 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. Features : Best operating efficiency water lubricated bearings Extremely hardwearing Highly durable Water cooled rewindable motor Can be easily dismantled and repaired Can handle more upthrust loads. Applications : Irrigation Civil water supply Fountains Industrial & Rural water supply Fire fighting Pressure boosting units Gardens Sprinkler systems and Mining.
