Product Introduction
The LG Vertical Split-Type Multistage Clean Water Pump for High-Rise Building Water Supply is a new-generation product developed to meet the actual needs of constant-pressure water supply and fire-fighting systems in high-rise buildings.
The hydraulic model of the pump is carefully designed by our technical engineers, giving the pump high efficiency, stable performance, low noise, long service life, attractive appearance, small installation footprint, convenient maintenance, and lightweight construction.
The pump and motor are connected as one unit. The pump shaft and motor shaft are linked by a clamp-type coupling to ensure perfect coaxial alignment, enabling stable operation with low noise.
The motor is a Y-series three-phase asynchronous motor, which makes replacement convenient for users. The rigid integrated connection requires no alignment during use. The shaft seal adopts a mechanical seal, and the split-type pump structure allows for easy replacement of the mechanical seal.
Viewed from the motor end downward, the LG split-type multistage pump rotates in a clockwise direction.
Product Features
The LG vertical split-type multistage water pump has a compact structure, small size, and attractive appearance. Its design minimizes installation area requirements, and with an optional protective cover, it can also be used outdoors.
The impeller is mounted directly onto the motor shaft to ensure perfect concentricity, enhancing operational stability and extending the service life of the pump.
The shaft seal adopts a mechanical seal or combination mechanical seal with high-quality alloy sealing rings, providing excellent wear resistance and longer service life.
Installation and maintenance are convenient and require no disassembly of the piping system. The pump inlet and outlet have the same diameter, which simplifies piping connections.
Depending on required flow and head, pumps can be used in series or parallel operation.
The inlet and outlet can be installed at 0°, 90°, 180°, or 270° to accommodate different installation conditions.
The pump head can be adjusted by increasing or decreasing the number of stages and by trimming the impeller diameter, without changing the installation footprint.
Product Applications
The LG vertical split-type multistage clean water pump is especially suitable for constant-pressure water supply in high-rise residential buildings, hotels, and office towers, as well as for fire-fighting and sprinkler systems.
It is also suitable for automatic water replenishment in cooling towers of chemical process systems; pressure stabilization; process circulation water; long-distance water transfer; boiler feedwater; and various water supply systems.
The pump is designed to handle clean water at normal temperatures (<80°C). The hot-water model can handle media up to 105°C, as well as liquids with physical and chemical properties similar to water.
Operating Conditions
The medium should be similar to water, with kinematic viscosity <150 mm²/s, free from hard particles, and non-corrosive.
Installation altitude should be <1000 m. For installations above this altitude, please inform us at the time of order so that we may provide a more reliable configuration.
Medium temperature range: –15°C to 120°C.
Maximum system working pressure: ≤2.5 MPa.
Ambient temperature should be below 40°C, and relative humidity should be below 95%.
Structural Description
The LG vertical split-type multistage clean water pump has a compact structure, small size, attractive appearance, and small installation footprint, reducing construction costs.
The suction and discharge ports are positioned along the same centerline, simplifying pipe layout and connections.
Depending on installation needs, the inlet and outlet can be configured at 90°, 180°, or 270°.
Depending on actual requirements, the pump outlet can be configured with 1 to 5 outlets on the same pump, enabling different heads from a single unit.
