The D series Multistage Ring Section Centrifugal Water Pump is a utility-grade, high-pressure, ring section pump with heavy duty, segmental ring, diffuser design. Axial thrust balance device with stacked rotor construction. Suitable for boiler feed pump and high building, long distance water transferring.
The pump could be applied to mining water handling by using wear-resistant material for the wet parts. Every mine faces unique source water and process water challenges, typically related to intake, quality, restricted access or effluent management. Sanchang tailors water and mining solutions to your location, with pumps and systems for transport and pressure boosting, reliable dewatering, mining water treatment and quality monitoring.
High operating reliability
* Axial thrust balancing by balance disc.
* Adaptation of pump casing to rotor deflection line.
Ease of service
* Easy maintenance of wear parts (bearings, seal elements,
balancing devices).
* Metal-to-metal sealing of casing.
Long service life
* Avoidance of cavitation erosion inside the pump through
hydraulically optimised inlet.
* Variant straight shaft design featuring increased operation
safety.
* Non-API and API 610 latest edition (BB4) constructions available
* Modular design for various number of stages
* “Blind” stages for future upgrades available
* Low NPSH first stage design is available
* Single or double mechanical seals
