Product Introduction
LG vertical dismantling high-rise building water supply multi-stage pump is a new generation of water supply product developed based on the actual needs of constant pressure water supply and fire protection industry in high-rise buildings.
The hydraulic model used for the LG vertical dismantling high-rise building water supply multi-stage pump has been carefully designed by our technical personnel, resulting in high efficiency, stable performance, low noise, long service life, beautiful appearance, small footprint, easy maintenance, and light weight;
The LG vertical dismantling high-rise building water supply multi-stage pump is connected by a motor and a pump, and the pump shaft is connected to the motor shaft with a clamp type coupling to ensure absolute coaxiality between the pump and the motor, resulting in smooth operation and low noise.
The motor is a Y-shaped three-phase asynchronous motor, which is convenient for users to replace. It is rigidly connected as a whole and does not require calibration during use. The shaft seal adopts a mechanical seal, and the pump adopts a detachable structure for easy replacement of the mechanical seal.
The rotation direction of the LG detachable high-rise building water supply multi-stage pump is clockwise when viewed from the motor end downwards.

Product Features
1. The LG vertical dismantling high-rise building water supply multi-stage pump has a compact structure, small volume, and beautiful appearance. Its structure determines that the installation area is small, and if a protective cover is added, it can be placed outdoors for use.
2. The impeller is directly installed on the motor shaft to ensure the concentricity of the pump, thereby enhancing the operational stability of the pump and extending its service life.
3. The shaft seal adopts mechanical seal or a combination of mechanical seals, and uses high-quality alloy sealing rings to enhance the wear resistance of the seal and effectively extend its service life.
4. Easy installation and maintenance, no need to disassemble the piping system. The inlet and outlet of the pump have the same diameter, simplifying the connection of the pipeline.
5. Pumps can be operated in series or parallel according to the needs of flow rate and head.
6. The suction and discharge ports can be installed in different directions such as 0 °, 90 °, 180 °, and 270 ° as needed to meet different connection scenarios.
7. The pump head can be increased or decreased according to the needs of the water pump stage and combined with the outer diameter of the cutting impeller to meet the requirements, without changing the installation footprint.

application
LG vertical dismantling high-rise building water supply multi-stage pump is particularly suitable for supporting pumps for constant pressure water supply, fire protection, and sprinkler water supply equipment in high-rise buildings such as residential buildings, hotels, and office buildings; Also applicable for automatic water replenishment of cooling towers in chemical processes; Used for stabilizing system voltage, circulating water in production processes, long-distance transportation, boiler feedwater and other water supply equipment.
The liquid that can be transported is at room temperature (<80 ℃) (hot water type can transport media with a temperature less than 105 ℃), clean water, or a medium with physical and chemical properties similar to water at room temperature.

Conditions of Use
1. The medium used should be similar to water, with a kinematic viscosity of<150mm2/s, no hard particles, and no corrosive properties;
2. The altitude of the environment used is less than 1000 meters. If it exceeds this, it should be raised during the order process so that our factory can provide you with more reliable products;
3. Medium usage temperature -15 ℃~120 ℃;
4. The working pressure of the large system is ≤ 2.5MPa;
5. The ambient temperature should be below 40 ℃ and the relative humidity should be below 95%.

STRUCTURE DESCRIPTION
1. LG vertical dismantling high-rise building water supply multi-stage pump has a compact structure, small volume, beautiful appearance, small footprint, and saves construction costs;
2. The suction and outlet of the LG vertical dismantling high-rise building water supply multi-stage pump are on the same centerline, simplifying the connection of pipelines;
3. According to the actual situation, the inlet and outlet of the pump can be assembled in different directions of 90 °, 180 °, and 270 °;
4. According to the actual situation, the outlet of the pump can be assembled into 1-5 outlets to meet different head requirements on the same pump;
