product name: LG type multi-stage feedwater pump for high-rise buildings
Caliber (import / export): φ25-φ80 (mm)
flow: 3.0-50 (m3 / h)
Head: 20-150 (m)

Product Overview:
LG type multi-stage feed pump for high-rise buildings is a vertical single-suction multi-stage segmented centrifugal pump, which is used to transport room temperature water and liquids with physical and chemical properties similar to water.
LG series pumps are installed vertically. The motor shaft and the pump shaft are connected by a claw-type coupling, which has the advantages of compact structure, low noise and small footprint.
Scope of application:
It is mainly used for water supply of high-rise buildings, and can also be used for water supply and drainage of factories and mines, and circulating water for low-pressure boilers.
Product features:
1. Advanced hydraulic model: high efficiency and wide range of performance.
2. Fewer operating and maintenance costs: high-quality mechanical seals, wear resistance, no leakage, long service life, low failure rate, and lower operating and maintenance costs.
3. Unique components and noise reduction: Unique hydraulic component design, good flow performance, and minimize flow noise.
4, vertical structure, small footprint.
4. Meaning of model:
Five, performance parameters:
Flow: 3.0-50m3 / h; Head: 20-150m; Power: 0.75-30kw; Speed: 2900r / min; Caliber: φ25-φ80; Temperature range: 0- + 80 ° C Working pressure: ≤1.2Mpa.
