The D series Multistage Ring Section Centrifugal Water Pump is a high pressure, ring sectional centrifugal pump with heavy duty, segmental wear ring, diffuser design. Axial thrust balance device with stacked rotor construction. Suitable for boiler feed pump, long distance water transferring, high building water supply.

The impellers are stacked in single direction on the same pump shaft. The rotor is balanced by the specially designed balance drum device. The rotors are perfectly dynamically balanced and the maximum stages can be up to 12stages.

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.
