The GC-type boiler feed water multistage pump is a horizontal, single-suction, multistage segmented centrifugal pump, mainly used for boiler feed water, hence also known as the boiler feed water pump. This series of boiler feed water pumps is suitable for transporting clear water or other non-corrosive liquids with physical and chemical properties similar to water at temperatures below 110°C. They are widely used for boiler feed water and urban domestic water supply in industrial, mining, and corporate units. The GC series pumps are particularly suitable for boiler feed water and can also be extensively applied in various industries such as pressure vessel water supply, hot water circulation, high-rise building water supply, agricultural irrigation, fire-fighting pressure increase, hydraulic flushing, food, brewing, chemical industry, aquaculture, environmental protection, chemical process flow, and machine tool matching, serving as power equipment for water supply and drainage.
