Under what working conditions can low-lift and high-flow water pumps be used?

There are many types of industrial water pumps, and of course there are many corresponding nicknames. Sometimes users will directly tell us the manufacturer about its purpose, such as low head and large flow, or large flow, high head, or large head and flow, so that we can choose the model.

The most common low-head and large-flow water pump is the split-center centrifugal pump, which is a major advantage of the split-center pump. The split-center pump has a symmetrical structure and a small overall footprint. It has horizontal and vertical structures.

In addition, axial flow pumps and mixed flow pumps are also low-head and large-flow water pumps. The appearance of axial flow pumps and mixed flow pumps is somewhat similar, and some people may not be able to tell them apart. These are two different industrial water pumps with different internal structures.

So what working conditions can these different types of low-head and large-flow water pumps be used in?

• Municipal water supply and drainage engineering

In the city's water supply system, low-lift and high-flow pumps can be used to draw water from water sources (such as rivers, lakes, reservoirs, etc.). For example, raw water is transported from large lakes around the city to the city's water supply plant. Because the city's water consumption is huge, a large-flow pump is needed to meet the demand, and the terrain difference between the water source and the water supply plant may be relatively small, so this low-lift (low-flow) pump is just right.

In the city's drainage system, it is used for rainwater discharge. When it rains heavily, a large amount of water on the road needs to be drained away quickly. Low-lift and high-flow water pumps can be installed in drainage pumping stations to pump rainwater from low-lying areas (such as underground passages, sunken squares, etc.) to nearby drainage rivers or sewage treatment plants.

• Agricultural irrigation field

For irrigation of large tracts of farmland, especially in plain areas. For example, in the large grain-producing areas of the North China Plain, the terrain is relatively flat, and irrigation water needs to be transported from canals or water sources (such as large irrigation reservoirs) to the fields. Low-lift, high-flow pumps can transport large amounts of water to vast farmlands at a relatively small lift to ensure that crops get sufficient water.

• Industrial circulating water system

Many industrial production processes require a large amount of cooling water to remove the heat generated by the operation of equipment, such as thermal power plants. In the cooling system of the power plant, a low-lift, high-flow water pump can transport cooling water from the cooling water pool to the condenser and other equipment to circulate the cooling water. Because the height difference between the equipment is generally not large, a large flow of water is mainly required to ensure the cooling effect.

• Cofferdam drainage in water conservancy projects

During the construction of water conservancy projects, such as building dams and bridge foundations, it is often necessary to set up cofferdams in the water area. There will be a lot of accumulated water in the cofferdam that needs to be discharged in order to carry out foundation construction and other work. Low-lift and high-flow water pumps can quickly and effectively discharge the water in the cofferdam to the water area outside the cofferdam, and because the water level difference inside and outside the cofferdam is usually not large, low-lift water pumps can meet the drainage requirements.

Of course, these are summarized by our manufacturers based on a lot of experience, but the specific working conditions must be treated specifically and the selection must be rigorous to ensure the overall solution of industrial pumps.
