1 STAINLE STEEL GRAND SERIES

2 STAINLE STEEL GRAND SERIES DEEPWELL SUBMERSIBLE PUMPS STAINLE STEEL - GRAND SERIES C.R.I. Always equips itself in advance to face the exponentially growing technological challenges across the industry and to gain high level of customer satisfaction. C.R.I. Introduced wide range of Stainless Steel-Grand Series Submersible Pumps to satisfy the increasing demand of both high flow and high head applications. These pumps are designed and developed using advanced technologies and integrated quality control programs backed by 5 years of profound experience which ensure low life cycle cost. These pumps are manufactured with highest levels of standardization and efficiency of use. This Stainless Steel Grand series pumps are available in 8, 1, 12 & 14 Nominal Diameters with a maximum flow upto 81 m³/h and maximum head upto 486 meters. These pumps are offered with complete Stainless steel construction to suit customers specific applications and aggressive water handling. Features : Best operating efficiency Precise parts made up of 316 Extremely hardwearing water lubricated bearings Highly durable & hygine Can be easily dismantled and repaired Can handle more upthrust loads Good resistance to sand and salt. Applications : Irrigation Civil Water Supply Industrial & Rural Water Supply Fire Fighting Pressure Boosting Units Sprinkler Systems Mining Oil & gas De-watering Food processing industries Golf course De-salination.

The Performance curves show pump performance at rated speed, voltage. b. The measurements were made with cold water (2 C) at atmospheric pressure (1bar). 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. Q/H : The curves are inclusive of suction inter-connector losses at the actual speed. e. "Y- Curve" indicates the NRV loss to be considered while selecting pump. f. Efficiency curve : h % shows pump stage efficiency. g. Curve tolerance according to ISO : 996, Grade 3B. h. The performances 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 performances are for specific materials of construction of pump. j. The outlet size of the pumps are as per BSP / GAS standard.
