ZD series multistage ring section pump is centrifugal type pump, with multipule impellers, side/vertical suction and vertical delivery, foot mounted.
The multistage pump is able to deliver the clear water or similar liquid which solids content is less than 1.5%, solids size is less than 1.3mm, temperature less than 120℃. By changing the pump material, structure, sealing etc, it could also deliver hot water, oil, corrosive and abrasive liquid.
1. Using the symmetrical setting impeller, which can eliminate the axial force for higher efficiency.
2. The bearing housing is designed as liquid preventing, which prolong the bearing service life and lower the maintenance cost.
3. The unique throttling, pressure reducing and balancing device for longer service life.
4. Precising casting parts for less pump maintenance.
5. Optimized hydraulic modular design, and double suction design for fisrt stage impeller, ensuring the pump working stable and favorable NPSH.
