Product introduction
Detailed Description: The D, DG, and MD series multistage pumps are segmented multistage centrifugal pumps, utilizing multiple impellers in series to achieve high-pressure delivery. These pumps are widely used in industrial water supply, boiler feedwater, and mine drainage applications.
D Type: Designed for clean water transportation, suitable for media temperatures ≤80°C.
DG Type: Specifically engineered for high-temperature, high-pressure boiler feedwater, withstanding temperatures up to 210°C.
MD Type: Built for wear-resistant mine drainage, capable of handling complex media containing solid particles (≤2%).
Users can select the appropriate pump material, sealing type, structural configuration, and motor capacity based on factors such as the transported medium, concentration, specific gravity, temperature, and pump inlet pressure.

Scope of application
Industrial field: In industrial production, multistage pumps are commonly used to transport corrosive liquids, high temperature and high pressure gases, etc.For example, in the petrochemical industry, multistage pumps are used to transport chemical media; in the power industry, multistage pumps are used to transport steam and hot water.
Urban water supply field: Multi-stage pumps are widely used in waterworks and sewage treatment plants to pump water from water sources to water towers or pipe networks to ensure the stability and reliability of urban water supply.
Farmland irrigation field: Multi-stage pumps are suitable for farmland irrigation, especially in areas with high terrain or remote irrigation, and their high lift and high flow characteristics are more suitable.
In the field of marine and offshore engineering: multi-stage pumps are used to transport fuel, lubricating oil, cooling water, etc.For example, in a ship, a multistage pump is used to extract fuel from the fuel tank to provide fuel for the engine.
Construction field: In high-rise buildings, multi-stage pumps are used to pump building water from the low-rise to the high-rise to meet the water needs of high-rise users.In a heating system, a multistage pump is used to pump hot water from the boiler room to the user's home.
Sewage treatment field: Multi-stage pumps are used for sewage lifting and transportation to ensure that sewage can be efficiently transported to the treatment equipment.
Fire protection field: Multi-stage pumps are used in fire hydrant systems and sprinkler fire extinguishing systems to provide sufficient water pressure to meet the fire extinguishing needs of high-rise buildings.
In the field of nuclear power: Multi-stage pumps are used to transport nuclear fuel and cooling water to ensure the safe operation of nuclear reactors.
Food and beverage industry: multistage pumps are used for liquid delivery in the food and beverage production process to ensure the smooth progress of the production process.
Application examples
Suitable for urban water supply: In waterworks, multi-stage pumps are used to pump water from water sources to water towers or pipe networks to ensure the stability and reliability of urban water supply.
Agricultural farmland irrigation: In farmland irrigation, multi-stage pumps are used to pump water from water sources into farmland to meet the needs of crop irrigation.
High-rise building water supply: In high-rise buildings, multi-stage pumps are used to pump building water from the low-rise to the high-rise to meet the water needs of high-rise users.
Water-based fire-fighting system: In fire hydrant systems and sprinkler fire-fighting systems, multi-stage pumps provide sufficient water pressure to meet the fire-fighting needs of high-rise buildings.
The high efficiency, high pressure and high flow characteristics of multistage pumps make them play an important role in many fields, ensuring the smooth progress of various fluid delivery tasks.
