          Hello Welcome to Shuangqiang (Jiangsu) Heavy Industry Technology Co., ltd.Official website! E-mail Login  | 

          Summary:
          1. IS the type pump series single-stage single-suction centrifugal pump, and adopt international standard ISO2858 design, BA type pump IS updated products, applicable to industrial and urban water supply, drainage, can also be used for agricultural irrigation and drainage. For conveying water or physical and chemical properties similar to water other liquid, the temperature is not higher than 80 ℃.
          ISR type is required by our company according to international standard ISO2858 performance and size design series hot water pump, suitable for hot water boiler feed water, hot water circulation system, can also be used in industrial and urban
          Water supply, drainage and irrigation, but the temperature does not exceed 150 ℃.
          2. IS (R) performance range (according to the design point) :
          Speed: 2900 r/min and 1450 r/min
          Import diameter: 50 ~ 200 mm
          Traffic: 6.3 ~ 400 m3 / h
          Head: 5 ~ 125 m
          3. The pump tag (for example IS (R) 80-6-16 0) :
          ISR (R) 80-65-160 - A... J (D)
          J - slow down pump performance
          A, impeller cutting class
          160 - the name of the impeller diameter (mm)
          65 - the outlet diameter (mm)
          80 - suction diameter (mm)
          IS (R) single-stage single-suction clean water centrifugal pump, hot water circulating pump)
          4. Choose the type of pump: users in the selection of the specifications of the pump, should pay attention to the following:
          (1) to choose the pump flow should be less than the normal water rate of Wells or other water, and dry season due consideration.
          (2) to choose the pump head should be according to the actual needs of head, and consider the pump line loss.
          (3) should be considered when choosing pump conveying liquid temperature, less than the prescribed temperature.
          (4) should be considered when choosing the pump installation height of pump, which sucked liquid surface to pump axis vertical distance, less than the height of the water pump regulation.
