T H E B E G I N N I N G of C.R.I., way back in 1961, was a resolute attempt to produce a few irrigation equipments using the limited facilities of an in-house foundry. Eventually the founder's dream was coming true as the small production unit he started kept growing rapidly. Now, after more than four eventful decades, it is an enormous, widely reputed organization, which produces more than 1 varieties of perfectly engineered pumps and motors and sells its products in numerous countries spread across 6 continents. C. R. I. I S N E A M N G the few pioneers in the world to produce 1% stainless steel submersible pumps. Having achieved a record production capacity of over 75, pumps per annum, today C.R.I. is rubbing its shoulders with the best brands in the world, with advanced technology and safety standards as its hallmarks. T H E I N F R A S T R U C T U R E of C.R.I. is pretty comprehensive with state-of-the-art machineries and a high potential R&D wing, all within its own covered area of 1, square metres. The production environment is accredited with IS 91 & 141 certifications. The R&D team always stays in tune with the changing scenario and seldom fails in coming up with outstanding solutions every time. N E E D E S S T S A Y, behind this legendary growth lies the untiring, innovative, enthusiastic and dedicated team work. And, of course, a flawlessly maintained value system too. The name C.R.I. itself encapsulates the company's ethos: Commitment, Reliability, Innovation.

G E N E R A C.R.I. Horizontal Multistage MH series pump is non-self priming, axial suction and vertical radial delivery type with threaded ports. All wetted components like impellers, diffusers and shaft of these pumps are made of corrosion resistant AISI stainless steel and designed to deliver the best possible hydraulic efficiency. The pump and motor are connected with a single drive shaft to eliminate any transmission loss. As the shaft, Impeller, diffusers and other vital components of the pump are made up of high grade stainless Steel AISI 34/316, these pumps can be used to pump high aggressive water and quite hygienic to use in drinking water systems too. ear resistant bearings ensure better hydraulic efficiency and noiseless operation and the pump casing & brackets are made of high quality cast iron. '' rings and gaskets prevent leakage at the intermediate casing during high pressure. Mechanical seals of these pumps are made of ceramic and carbon graphite to ensure reliability and easy replacement. These pumps are reliable, easy to install and designed for high end user comfort. C.R.I. Horizontal Multistage centrifugal pumps are powered by a Totally Enclosed Fan Cooled, A.C. induction motor, suitable for continuous duty. Motor stator is made of low watt loss steel laminations assembled under pressure and rigidly locked in the frame. Dynamically balanced rotor ensures vibration and noise free operation and the varnished impregnated windings made of enameled copper wire offer excellent resistance. Shaft of ample size made of quality steel and precisely ground is used for transmitting the rated Horsepower. Construction of motor frames and usage of quality materials result in high performance and low temperature rise thereby increasing the life cycle of the motor. Thermal over load protector (motor protector) is incorporated in single phase motors. These pumps require an adequate motor protection control panel. Applications : Industrial and Domestic water pressure boosting and distribution, Small farms, Gardens, Pumping of clean liquids in industry, Car washing.
