The HW(HBC) series mixed-flow pumps are horizontal single-stage single-suction volute-type mixed-flow pumps. The pipe diameters available are 100, 150, 200, 250, 300, 350, 400, 500, 600, 650, 700, and 800. The flow rate ranges from 60 to 9,000 cubic meters per hour, and the head ranges from 3 to 20 meters. All the products are of the front and rear opening structure. During maintenance, there is no need to dismantle the pipelines. This is a significant improvement in the structure of our company's mixed-flow pumps, which greatly facilitates the use, maintenance and repair of users. The inlet of the pump is horizontal, and there are two outlet forms: vertical outlet (upward) and horizontal outlet (downward). The installation method of this series of pumps is usually horizontal suction-up installation, and there is also inclined semi-sunken installation. Users can choose according to the design requirements, local water level changes and usage habits. It is suitable for transporting clear water or other liquids with physical and chemical properties similar to water. The temperature of the transported liquid should not be higher than 50℃. It is widely used in various occasions such as farmland irrigation, industrial and urban water supply and drainage.

2. Characteristics:
Simple structure, reliable operation, easy to assemble and disassemble, small size, light weight, large flow rate, high efficiency.
3. Transmission method:
There are two types: direct drive and belt drive. The commonly used power machines are electric motors and diesel engines. When placing an order, the model (power and speed) of the power machine should be specified so as to determine the specifications of the pulley or coupling.
4. Pump rotation direction:
From the perspective of the pump inlet, the impeller rotates counterclockwise.

Application fields

The HW type high-flow mixed-flow pump is the key power for achieving regional water volume allocation and elevation. Its core application scenarios include:
Large-scale agricultural irrigation and flood control and drainage: backbone pumping stations for cross-basin and large-scale irrigation areas, regional flood control and drainage pumping stations in plain river networks.
Municipal water supply and rainwater management: urban rainwater pumping stations, internal river water level regulation pumping gates, and inlet pump rooms and tail water discharge of sewage treatment plants.
Industrial and power plant circulating cooling: main pumps for circulating cooling water in thermal power plants and nuclear power plants, serving as the core equipment to ensure the operation of the units.
Water conservancy projects and ecological water diversion: lifting pumping stations in cross-regional water resource allocation projects, water intake and replenishment projects of reservoirs and lakes, and ecological flow guarantee projects for water supply.
Shipyard and waterway engineering: water drainage and irrigation for large shipyards, water replenishment after waterway dredging, and supporting projects of water conservancy hubs.
