Product Introduction
The GW unobstructed pipeline sewage pump is developed using advanced technology through absorption and conversion, and its performance indicators have reached the national standard for similar products. Due to the use of unique single (double) channel impellers, it has strong drainage capacity and can effectively pass through 5 times the diameter of the pump and solid particles with a diameter of 50% of the pump diameter. The dynamic seal adopts two sets of special hard alloy mechanical seal devices made of cast iron and stainless steel.

Product Features
The GW unobstructed pipeline sewage pump is a new type of pump designed using advanced technology based on the ISG vertical pipeline centrifugal pump. This pump can be used as a general pipeline pump for pressurized water delivery, as well as for pumping liquid impurities containing particles, fibers, suspended solids, and other impurities. It provides an ideal conveying machinery for industries such as chemical, textile, pharmaceutical, and environmental protection.

scope of application
The GW pipeline sewage pump is suitable for the discharge of severely polluted wastewater in factories and commercial areas, sewage discharge stations in main residential areas, water distribution systems in urban sewage treatment plants, drainage stations in civil air defense systems, water supply equipment in water plants, sewage discharge in hospitals and hotels, municipal engineering construction sites, mining auxiliary machinery, rural biogas digesters, farmland irrigation and other industries. It can also be used to transport granular sewage and pollutants, as well as clean water and weakly corrosive media.
