Product Brief

LG, LG-B vertical multistage centrifugal pump is a new generation of products according to the actual need of development of high-rise building water supply of constant pressure water supply and fire industry. Using the domestic advanced hydraulic model of the pump, carefully designed the factory technical personnel, so the pump with high efficiency, stable performance, low noise, long service life, the use of the advantages of beautiful appearance, small occupation area, convenient repair, light weight etc..

LG vertical multi-stage centrifugal pump is composed of motor and pump are linked together, the pump shaft and motor shaft with shell type shaft coupling, pump and motor to ensure absolute coaxial pump run smooth, low noise phenomenon. The motor for the Y type three-phase asynchronous motor, is convenient for user to replace, the whole is rigid connection, with no need of correction. Seal with mechanical seal, pump for the detachable type structure is convenient for the replacement of mechanical seals.

LG vertical multistage centrifugal pump direction of rotation from the motor side look down for the clockwise direction of rotation.

The scope of application

For residential, hotels, office buildings and other high-rise buildings, fire control, constant pressure water supply spray with pump matching water supply equipment; automatic replenishment is also suitable for the cooling tower of chemical process; voltage system, production process water recycling, long-range transport, water supply equipment for boiler feed water etc.. Can transport liquid at normal temperature (<80 DEG C) (hot water type transmission temperature is less than 105 degrees medium) at room temperature, medium water or the physical and chemical properties similar to water.

Product features

1, LG vertical multistage centrifugal pump has the advantages of compact structure, small size, beautiful shape, the structure decided to install a small area, such as protective cover can be placed outdoors.

2, the impeller mounted directly on the motor shaft, so as to ensure the concentricity of the pump, thus enhancing the stability of pump operation and prolong the service life of the pump.

3, seal with the combination of mechanical seal or mechanical seal, with high quality alloy sealing ring, enhance the wear resistance of the seal effectively prolong life.

4, easy installation and maintenance, no need to open the pipeline system. Pump imports and exports for the same caliber, simplifies the connection of pipeline.

5, can be used to pump in series and parallel operation mode according to the need of flow and pressure.

6, according to the need, inlet and outlet can be arranged into 0 degrees, 90 degrees, 180 degrees, 270 degrees in several directions to meet the connection in different occasions.

7, the lift of the pump can be increased or decreased according to the requirement of pump series and the combination of cutting impeller diameter to be met, without changing the installation area.
