LG high-rise buildings multi-stage water-supply pumps.LG Series pumps for vertical installation, motor shaft and pump shaft are connected through the claw-type Couplings with compact structure, low noise, small footprint and so on. The Division products are all designed and optimized by computer processing, the company has strong technical force, rich production experience and perfect detection means, so as to ensure product quality stable and reliable.
the scope of application:
mainly be used in high-rise buildings as well as be used in factories, mines, enterprises and low-pressure boiler warter supply. the product features:
1, advanced hydraulic model: high efficiency, widely be used.
2, less operating and maintenance costs: use of high-quality mechanical seal, wear-resistant, non-leakage, long service life, failure rate is low, with fewer operating maintenance costs.
3, unique parts, reduce the noise: unique hydraulic component design, good performance, biggest reduction for flow noise.
4, vertical structure, small footprint.
