Product Description

DG series Boiler Feed Pump / Multistage Ring Section Centrifugal Pump for Hot Water

Advantages :

1. DG series Boiler feed pump / horizontal multistage centrifugal pump / Ring section centrifugal pump. 

2. No balance plate, wider performance range.

3. 5%-15% higher efficiency than the old style common multistage pump.

4. Directly coupled, vibration proof and low noise.

5. Circulating flow cooling ensure mechanical seal long life.

6. Excellent seal that is no leakage.

7. work steadily and safely.

8. Low noise,less easy-wearing parts and easy for maintaining.
