Horizontal Ring Section Multistage Centrifugal Water Pump 200D43X3 (Bare Shaft Pump)
Description
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.
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.
Features
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.
Reduced energy costs
* No pre-warming of pump required.
* More than 100 impeller/diffuser combinations with optimum
efficiencies possible.
Application
* boosting in General Industries of chemical process
* Sewage Treatment Plant
* Marine & offshore
* Power Plant
* Sea Water Desalination
* Petrochemical processing
* Clear and lightly contaminated liquids
* Commercial water supply, High building water supply
* Mining water discharge
