Heavy duty water pump/multistage centrifugal industrial pump
Advantages:
1. ZD tpye horizontal multistage centrifugal electric pump, introduced the technology from CLYDE UNION PUMP.
2. No balance plate, so 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. 
Application:
Heavy duty water pump/multistage centrifugal industrial pump apply as the transportation of liquids in the fields of steel factory, Mining, chemical factory, sewage water dealing treatment, water treatment cooling, refrigerating system, Liquid circulation, water supply, pressure boosting, sea water delivery, steamer system and irrigation etc.
