LG-B Vertical multistage centrifugal pump

LG series vertical multistage pump is used for conveying clean water at room temperature and other similar liquids to clean water in physical and chemical properties.

LG series multistage pump is for vertical installation, the motor shaft and the pump shaft is connected by jaw coupling. The pump has the features of compact structure, low noise, small volume etc.

LG Vertical multistage pump is mainly used in high-rise building water supply, water supply and drainage can also be used in factories and mines, enterprises, and low pressure boiler water circulation. Application: mainly used in high-rise building water supply, water supply and drainage can also be used in factories and mines, enterprises, and low pressure boiler circulation use.

LG detachable high-rise building water supply is a new generation of water supply products developed according to the practical needs of constant pressure water supply for high-rise buildings and fire fighting industry.

This pump adopts the domestic outstanding hydraulic model and has high efficiency ,stable performance, low noise ,long service life, beautiful appearance, small occupation area ,convenient maintenance is convenient and light weight etc.

LG detachable high-rise water supply multistage pump is connection motor by jaw coupling between pump shaft and motor shaft . It ensures that the pump and motor absolutely coaxial make the pump run smoothly, low noise phenomenon. The motor is Y type three-phase asynchronous motor. The shaft seal adopts mechanical seal, and the pump is of detachable structure to facilitate the replacement of mechanical seal.

LG detachable high-rise water supply multistage centrifugal pump rotation direction from the motor end is for clockwise rotation.

Product features:

1, LG will be split high-rise building water multistage structure compact, small volume, beautiful appearance, the structure of the decision to install an area of small, such as the protection cover can be placed in the outdoor use.

2. The impeller is directly mounted on the motor shaft to ensure the concentricity of the pump, thus enhancing the operation stability of the pump and extending the service life of the pump.

3. The shaft seal adopts mechanical seal or combination of mechanical seal and adopts high-quality alloy sealing ring to enhance the wear resistance of the seal and effectively extend its life.

4. Easy installation and maintenance, no need to remove the pipeline system. The inlet and outlet of the pump are of the same caliber, which simplifies pipeline connection.

5, according to the flow rate and the need to use the pump series, parallel operation mode.

6. The inlet and outlet can be installed in different directions of 0°, 90°, 180° and 270° to meet different connection occasions.

7, pump head can be according to the need to increase or decrease the pump series and combined with the cutting impeller diameter to meet, and do not change the installation area, which is not available for other pumps.

application:

LG dismounted multi-stage centrifugal water supply pump for high-rise buildings is especially suitable for residential buildings, hotels, office buildings and other high-rise buildings constant pressure water supply, fire, spray water supply equipment supporting pumps; It is also suitable for automatic water replenishment of chemical process cooling tower. For water supply equipment, such as system pressure stabilization, circulating water in production process, long-distance transportation, boiler feed water, etc. The liquid that can be transported is normal temperature (<80℃)(medium with hot water type and conveying temperature less than 105 ℃) clean water or medium with physical and chemical properties similar to water at normal temperature.

Conditions of use:
