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.

It is a radially split, segmented casing, multistage pump designed with modular interstage components. These identical components can be assembled to produce pumps of varying numbers of stages, hydraulics, materials, and configurations to meet the customer’s specific requirements. Its multiple suction nozzle and discharge nozzle orientations allow the D to adapt to multiple piping installations and provide the piping designer with flexibility in plant layout.

The pump could be applied to varied kinds of application by using different material for the wet parts and seal flushing plans. Every application 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, sewage water treatment and quality monitoring.

Structure Design

Horizontal, radially split, ring section pump with radial impellers, single or double flow entry, multistage. The stages are sealed against each other by O rings or by metallic sealing faces and fastened by tie bolts.

Balancing Device
Thrust compensation by the hydraulic balancing device located at the discharge side. Balancing by disc or double piston.

The balancing device on centrifugal pumps is designed to fully or partially compensate axial thrust generated by the pump rotor. Designs incorporating a single balance drum or double drum require a thrust bearing to absorb the residual thrust.

The difference between a balance disk and a balance drum is whether the primary pressure drop is taken across a radial clearance (drum) or an axial face (disk). Some pumps use a combination drum/disk that incorporates both radial and axial clearances.
