The GC type boiler feedwater multistage pump
Overview:
The GC type boiler feedwater multistage pump is a horizontal, single-suction, multistage segmented centrifugal pump, mainly used for boiler feedwater, hence also known as a boiler feedwater pump. This series of boiler feedwater pumps is suitable for transporting clean water or other non-corrosive liquids with a temperature below 110°C, whose physical and chemical properties are similar to water. Widely used in boiler feedwater for industrial and mining enterprises, as well as urban domestic water supply. The GC series pump is especially suitable for boiler feedwater, and can also be widely used in pressure vessel water supply, hot water circulation, high-rise building water supply, agricultural irrigation, fire protection, hydraulic washing, food, brewing, medicine, chemical industry, aquaculture, environmental protection, chemical process, and machine tool matching industries, serving as a power equipment for water supply and drainage.
Features of GC Multistage Pump:
The GC pump is a multistage segmented pump. The inlet and outlet of the four models, 1-1/2GC to 4GC, are located respectively on the inlet and outlet sections, all vertically upwards. The head of the pump can be increased or decreased according to the application by adjusting the number of pump stages. The assembly of the pump is crucial for its performance. Especially, the relative position between the outlet of each impeller and the inlet of the guide vane must be aligned, otherwise, even a slight deviation will lead to reduced flow rate, decreased head, and reduced efficiency. Therefore, attention must be paid during assembly and adjustment after maintenance.
Main Components of GC Pump:
The main components of the GC pump include the shaft, shaft sleeve, inlet section, impeller, sealing ring, middle section, outlet section, balance ring, balance plate, and tail cover.
