Product Details

Introduction:

1.DL Multistage centrifugal pump. for high rise building has the advantages of advanced designing, compact structure, energy conversation, small floor space, easy installation, stable performance, etc.

2. The high head water pump always be used to supply water for high building, fire fighting system, central heating system, etc.

3. Multistage pump is with higher head (discharge pressure) than regular single stage one.

4. Widely used in water supply or drainage of high-rise building, fire control system, heating system, air-conditioning system, hotels, supermarket, office building, factories, industries and mining enterprises, municipal engineering, spray system, boilers, chemical industry, etc.
