II. Product Applications

LVG high-efficiency vertical long-shaft pumps are suitable for industries such as steel mills, power plants, oil wells, mines, 

metallurgy, power, energy, chemical, building materials, coal plants, water utilities, hospitals, pharmaceuticals, construction, 

fire protection, shipyards, and offshore platforms, as well as municipal water supply and drainage projects, agricultural irrigation,

 flood control and drainage projects. They are used to transport media such as clean water, rainwater, pit sludge, sewage, leachate, 

condensate, and seawater, and can also be used in certain chemical processes.

especially suitable for high-head applications. 2. Power Industry: Used in power plant circulating cooling water, hot water transportation,

 boiler feedwater and circulating water systems, fly ash water and coal slurry pumping, and turbine generator sets in hydropower stations.

3. Metallurgy and Mining: Transportation of iron oxide scale water and turbid circulating water, circulation of high-temperature waste 

slag liquid and molten medium coolant, closed conveying systems in dusty environments, slag flushing systems and slurry return water 

lifting, transportation of acidic waste liquid (mine water) and corrosive media, circulating cooling water systems for metallurgical equipment,deep mine drainage systems, transportation of high-concentration slurry and tailings, tailings dam return water, emergency drainage and flood control.

4. Municipal Water Supply: Deep well water lifting, rainwater pumping stations and flood control and drainage projects, landfill leachate 

transportation, sewage pumping station lifting, water supply systems, etc.

5. Sewage Treatment: Used in sewage lifting, sewage treatment, and sewage discharge.

6. Shipbuilding Industry: Used in ship cooling systems, drainage systems and water supply systems, and ballast tank injection and drainage.

7. Chemical and Pharmaceutical Industries: Circulation and transportation of sulfuric acid, hydrochloric acid, alkali solutions, and organic solvents.

8. Environmental Protection: Wastewater treatment, sludge dewatering, acid-base neutralization, and leachate transportation.

9. Energy: Liquid transportation on oil and gas platforms, high-temperature liquid lifting in geothermal energy development, 

cooling circulation in distributed energy systems, and bottom drainage and reinjection of residual liquid from oil storage tanks.

10. Agriculture: Deep well water extraction and groundwater irrigation, large-scale irrigation areas and inter-basin water transfer projects,

 continuous water supply during dry seasons with low water levels, transportation of sediment-laden river and canal water, flood control, 

drainage, and emergency drainage.

11. Offshore Platforms: Firefighting systems for offshore oil platforms, seawater lifting systems, and seawater desalination systems.

IV. Product Structure

The LVG high-efficiency vertical long-shaft pump is a vertical single-stage (multi-stage) centrifugal or oblique-flow pump with guide vanes.

 The suction inlet is vertically downward, and the discharge outlet extends horizontally. The pump and motor are directly connected. 

Viewed from the motor or right-angle gearbox end, the pump rotates counter-clockwise, requiring no vacuum for start-up. 

The rotor assembly is available in two forms: removable (pump diameter 1000mm and above) and non-removable (pump diameter below 1000mm).

• According to the installation method, it is divided into single-casing pumps (pump and motor directly connected and installed on one

 foundation layer) and double-casing pumps (pump and motor installed on two separate foundation layers).

• According to the structural type, there are pump discharge outlets above the installation foundation with the motor bearing axial force

 (pump diameter 1000mm and above), pump discharge outlets below the installation foundation with the pump bearing axial force 

(pump diameter below 1000mm), and pumps with external lubrication and self-lubrication.

• There are two types of pump suction tanks: wet pit and dry pit. Wet pit installation: The bottom of the pump is submerged in the suction tank.

 Dry pit installation: The pump uses a pipe for water intake, and a 90° elbow-shaped inlet bend connects the pump suction inlet to the inlet pipe.
