Horizontal Single-Stage Single-Suction Pipeline Centrifugal Pump For Circulation And Water Supply
The DBW series horizontal pipeline pump represents a bold structural upgrade of the original ISG pump, incorporating its advantages while enhancing the overall design. Its performance parameters conform to ISO 2858 standards, and product quality complies with JB/T53062-93 standards. Its technical performance indicators have reached an advanced level among similar products both domestically and internationally.
Thanks to the direct connection between the motor and the pump, the DBW horizontal pipeline pump simplifies the intermediate transmission structure, improves operational stability, and reduces the footprint by 30% compared to conventional horizontal pumps. The shaft seal adopts a hard alloy mechanical seal, ensuring long service life. It also features low noise, low vibration, and easy maintenance.

Horizontal Pipeline Pump Applications
DBW series horizontal pipeline pumps can be used to transport liquids below 80°C without solid particles or similar physical and chemical properties to water, as well as light corrosive liquids. This pipeline pump is mainly used in industrial and civil building fixed fire systems (hydrant fire extinguishing system, automatic sprinkler system, and water spray fire extinguishing system, etc.), for water supply.
Our pipeline centrifugal pump's performance parameters meet fire protection requirements while taking into account the needs of domestic (production) water supply. The product can be used in independent fire water supply systems, as well as in shared fire and domestic (production) water supply systems. It is also suitable for applications such as construction, municipal, industrial, and mining water supply and drainage, and boiler water supply.
