C.R.I. PUMPS
C . R . I . I S O N E A M O N G the few pioneers in the world to produce 100% stainless steel
submersible pumps. Having achieved a record production capacity of
over 2 million 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 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
five eventful decades, it is an enormous, widely reputed organization,
which produces more than 1800 varieties of perfectly engineered
pumps and motors and sells its products in numerous countries spread
across 6 continents.
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 high potential in-house R&D recognised by the ministry of
science and technology, Govt. of India - all within its own covered area
of 300,000 square metres. The production environment is accredited
with ISO 9001 & 14001 certifications and the products are CE, UR/UL,
IEC, TSE & ISI certified. 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 L E S S T O 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’’.
Pumping trust. Worldwide.
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 304/316, these pumps can be used to pump high aggressive water
and quite hygienic to use in drinking water systems too. Wear resistant
bearings ensure better hydraulic efficiency and noiseless operation and the
pump casing & brackets are made of high quality cast iron. 'O' 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 : | Residential & Industrial Pressure Boosting | Small farms | Washing systems | Industrial water supply | HVAC | Reverse
Osmosis systems | Food processing industries | Golf course.

HORIZONTAL MULTISTAGE PUMPS
Curve tolerance are according to ISO 9906, Grade 2B.
The performance are taken at rated voltage & speed that are only indicative.
Actual discharge depends on availability .of water in well / tank, height of water column from the suction pipe end
The measurements were made with airless water O at 20 C. When pumping liquids with a density higher than of water, motors with correspondingly
higher outputs must be used.
The bold curves indicate the recommended . performance range
Pipe fiction losses have not been included in the .performance curves & performance tables

HORIZONTAL MULTISTAGE PUMPS
C.R.I. MH series pumps are designed to deliver the best possible hydraulic efficiency. The pump and the motor are connected with a single
shaft to eliminate any transmission loss. Wear resistant bearings ensure better hydraulic efficiency and noiseless operation and the pump
casing & bracket are made of high quality cast-iron. Dynamically balanced rotor ensure vibration and noise free operation. Shaft of ample size
made of quality steel and precisely ground is used for transmitting the rated horsepower. Thermal over load protector is incorporated in single
phase motors. These pumps are reliable, easy to install and high end user comfort.
