LG multistage centrifugal vertical water pump for high building supply water.
LG Vertical multistage centrifugal pump is widely used to transport clear water with temperature less than 80 degree Celsius (or hot water with temperature less than 105 degrees) and other similar liquids.
LG type vertical multistage centrifugal pump is suitable for residential buildings, hotels, office buildings and other high rise buildings constant pressure water supply, fire, spray water supply equipment supporting pumps. It is also suitable for automatic water replenishment of cooling tower in chemical process. It is used for water supply equipment, such as system voltage regulation, production process circulating water, long-distance conveying, boiler feed water, etc.
Performance range:
Flow rate:2.4 to 90m3/h,
Head:15 to 200m
Liquid temperature: -15 to 105 degree Celsius
Environment temperature: no higher than 40 degree Celsius
System maximum working pressure: no higher than 2.5MPA
Advantages:
1.LG Vertical multistage centrifugal pump has compact structure, small size, eautiful appearance, small installation space with saving construction cost.
2.Pump Suction inlet and outlet are on the same central line which simplifies the pipeline connection.
3.According to the actual situation, pump suction inlet and outlet can be assembled into 90, 180,270 angle in different direction.
4.According to user’s demand, pump outlet can be assembled with 1 to 5 outlets in order to achieve different head on the same pump.
