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.

FAQ
-
How do I select the right ISG vertical inline centrifugal pump?
Select the pump according to required flow, head, pipeline diameter, liquid temperature, power supply and actual operating conditions. ZLZB® can recommend a suitable ISG model based on your system requirements. -
What liquids can an ISG vertical inline centrifugal pump handle?
Standard ISG pumps are mainly designed for clean water and liquids with physical and chemical properties similar to water. For corrosive, oily or special-temperature liquids, a different pump type should be selected according to the actual medium. -
What is the difference between ISG and IHG vertical inline pumps?
ISG pumps are mainly used for clean-water supply, circulation and pressure boosting, while IHG pumps are designed for compatible corrosive liquids and applications requiring corrosion-resistant materials.
-
What is the maximum liquid temperature for a standard ISG pump?
Standard ISG vertical inline centrifugal pumps are generally used for liquids below 80°C. For higher-temperature water circulation, a suitable hot-water pump type should be selected according to the operating temperature. -
Where are ISG vertical inline centrifugal pumps commonly used?
ISG pumps are widely used for industrial and municipal water supply, building pressure boosting, HVAC circulation, garden irrigation, fire-water boosting and long-distance water transfer. -
What information is required for an ISG pump quotation?
Please provide the required flow, head, pipeline diameter, liquid type and temperature, voltage, frequency and application. ZLZB® can then recommend the appropriate ISG vertical inline centrifugal pump and prepare a quotation.
