1 SELF-PRIMING WASTE WATER & DEWATERING PUMPS ECN & ECD SERIES An ISO 91 & ISO 11 Company

2 C.R.I. PUMPS 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 15 varieties of perfectly engineered pumps and motors and sells its products in numerous countries spread across 6 continents. C. R. I. I S O N E A M O N G the few pioneers in the world to produce 1% 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 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 3, square metres. The production environment is accredited with ISO 91 & 11 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.

4 X XXX NON CLOG - SELF PRIMING PUMPS ECN SERIES 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. SPECIAL FEATURES Easy removable of rotating assembly and front cover assembly Better solid handling capacity Liquid with slight gas particles can also be pumped Easy to install, operate and maintain Heavy duty bearings ensures longer life APPLICATIONS Construction, mining and industrial dewatering Municipal sewage water Agriculture and residential waste water Hospitals, hotels and all other commercial buildings Sewage treatment plants OPERATING CONDITIONS The temperature of the medium should not be more than C The density of the medium is x 1³ kg/m³ and the PH value is within 5-9 Max. solid size should not exceed the pump solid handling capacity Max. suction lift should not be more than 7m Max. working pressure is bar MODEL IDENTIFICATION CODE XX X - EC - End Suction Centrifugal Type of Impeller M - Multi Channel Semi Open Impeller D - Double Channel Semi Open Impeller N - Non-clog Dewatering Pumps Port Size in mm (5=5, =) 2
