LG, LG-B vertical multistage centrifugal pumps

introductions

LG is vertical, single stage multi-suction segmental centrifugal pump, product according to JB/T2727-93 "vertical multistage simple centrifugal pump type and basic parameters" standard, its inlet, outlet are located on the inlet and outlet segment. Rotor part is composed by shaft, impeller, impeller blocking sleeve, bushings, etc. inlet, middle, outlet section is joint by draw-in bolt. Shaft seals use soft packing seal or mechanical seal, using balance chamber pressure water to lubrication and cooling

features

Using pipeline structure easy installation, compact structure, cover small floor area, high efficiency and energy saving, low noise. Temperature is below 80 degrees, flow: 5-150m3/h head: 20-120m rotate speed 2900r/min

product usages

Applicable in high-rise buildings living water, high-rise building fire water, factory and mines, enterprise water, drainage, low-pressure boiler circulating water. Medium temperature between 0℃~80℃ conveying clean water or physical properties similar to water liquids.
