The ZLB type pump is a single-stage vertical axial flow pump, while the ZWB and ZXB types are extra-large horizontal and oblique axial flow pumps, which are suitable for pumping clean water, sewage, rainwater and slightly corrosive liquids, and the temperature of the transported liquid is not higher than 50°C. This type of pump is a large-flow, low-lift pump, which can be used for farmland irrigation and drainage, water conservancy projects, urban water supply, drainage and sewage treatment, power plants, salt plants and farms to transport circulating water, dock water level, and can also be used in metallurgy, chemical industry and other industries, and is widely used.
For vertical axial flow pumps, the pump and motor are installed on two foundation layers respectively, the axial thrust of the pump is borne by the motor, the pump bearing is a rubber guide bearing, and the seal is a packing seal. For horizontal (oblique) axial flow pumps, the entire pump system consists of hydraulic flow channels, pump body, transmission, motor and auxiliary equipment. The transmission part is a gear reducer.
