ISG Vertical Inline Centrifugal Pump

Single-Stage Vertical Inline Pump for Water Supply, HVAC Circulation & Pressure Boosting

ISG vertical inline centrifugal pump is a single-stage, single-suction centrifugal pump designed for clean water and liquids with physical and chemical properties similar to water. Its suction and discharge ports have the same nominal diameter and are arranged on the same centerline, allowing the pump to be installed directly into the pipeline while saving installation space. The ISG series is widely used for industrial and municipal water supply and drainage, building pressure boosting, HVAC cooling and heating water circulation, irrigation, long-distance water transfer and general equipment circulation. ZLZB® provides ISG pump selection based on required flow, head, liquid temperature, pipeline diameter, power supply and actual operating conditions.

Flow Range:

8.2-1500 m³/h

Head Range:

7-158 m

Power Range:

0.18–220 kW

Summary

ISG vertical inline centrifugal pump is a single-stage, single-suction pipeline pump designed for clean water and liquids with physical and chemical properties similar to water. The vertical inline configuration places the suction and discharge connections at the same nominal diameter and on the same centerline, allowing the pump to be integrated directly into the piping system while reducing installation space. The ISG series is widely used for industrial and municipal water supply and drainage, building pressure boosting, HVAC cooling and heating water circulation, garden irrigation, fire water boosting, long-distance water transfer and equipment circulation. ZLZB® provides ISG pump selection according to required flow, head, pipeline size, liquid temperature, power supply and actual system operating conditions.
