SELF-PRIMING

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 1500 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’’.

ECN series pumps are of non-clog, self-priming centrifugal type that are uniquely

designed for varied waste water pumping applications. Most modern and highly

sophisticated machineries and technologies are employed in the manufacture of

these pumps using quality raw material, dynamically balanced impellers, seals and

bearings to ensure long life. The special features like removable front cover &

removable rotating back assembly facilitates to limit pump's break down time. The

casing and impeller are designed for a better solid handling capacity and keeps the

pump clog free. These pumps are used for special applications such as municipal

sewage and industrial dewatering system.
