GENERAL INFORMATION STAINLESS STEEL, SILVERLINE, EVERGREEN & GOLDLINE SERIES PERFORMANCE CURVE CONDITIONS The conditions below apply to the curves shown on the following pages. a. The Performance curves show pump performance at rated speed, voltage and @ 1ft minimum submergence. The speed of motor is approximately : 3 motor : n = 28 rpm 4 motor : n = 29 rpm 6 motor : n = 29 rpm 8 motor : n = 29 rpm b. The measurements were made with airless water at 2 C. When pumping liquids with a density higher than that of water, motors with correspondingly higher outputs must be used. c. Pipe friction losses have not been included in the performance curves and performance tables. d. The bold curves indicate the recommended performance range. e. Q/H : The curves are inclusive of check valve and suction inter-connector losses at the actual speed. f. Efficiency curve : EFF % shows pump stage efficiency. g. Curve tolerance according to ISO : 996, Annex - A. h. The performance are at rated voltage and are only Indicative. Actual discharge depends on availability of water in well, based on strength of water source, height of water column, submergence of pump, etc.,. i. The given performance are for a specific materials of construction of pump. j. The outlet size of the pumps are as per BSP standard. In view of continuous developments, the information / descriptions / specifications / illustrations are subject to change without notice. 1

C.R.I. PUMPS GENERAL INFORMATION STAINLESS STEEL SERIES 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. 4, 6 & 8 Stainless steel series submersible pumps are made of corrosion resistance stainless steel with built in check valve. All vital components of these pump models are made of high quality 34 / 316 grade stainless steel and the shaft is of S.S 34 / 329 / 431. The optimal design of impellers and diffusers enables the best possible hydraulic efficiency. These pumps are of multistage centrifugal type, which can be 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 hammer. All mounting dimensions of pumps and motors are in accordance with NEMA standards. C.R.I. submersible pumps can be offered with either C.R.I. W' series, water filled rewindable submersible motors / C.R.I. 'R' series, encapsulated semi wet type submersible motors or any other NEMA standard motors. Features : l More longevity & hygiene l Precise parts made of S.S 34 / 316 l Shaft is of S.S 34 / 431 / 329 l High operating efficiency l Highly durable & rigid in construction l Good sand & abrasives l resistance against Easy to dismantle & repair mounting standards l Can handle high upthrust loads Extremely hardwearing water lubricated bearings l Built-in l NEMA l check valve to prevent back flow. Applications : l Domestic & Civil Water Supply l Irrigation l Fountains l Industrial & Rural water supply l Fire fighting & Pressure Boosting units l Ponds l Gardens l Sprinkler Systems and Mining. 3
