Horizontal Ring Section Multistage Centrifugal Water Pump 300-440m3/H

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.



The D series comprises single-casing radially split multistage between
bearings pumps, referred to as BB 4 type pumps in API 610. These pumps are
also known as ring section pumps, segmental ring pumps, or tie rod pumps.



The modular design of the D series pumps allows us to find the most
efficient solution to meet customer requirements. Both investment cost and
lifecycle costs are taken into consideration when designing the best
possible pump, and the optimized hydraulic design guarantees the highest
level of efficiency.



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.


Features and Benefits
* Greater reliability from radially split pressure casings, ensuring overall
pump concentricity and rotor alignment.
* Improved service life and tolerance to changing conditions due to
precision-cast diffusers that equalize radial loads and increase bearing,
wear ring and seal life.
* Decreased maintenance costs and longer service intervals enabled by heavy-
duty rotor with short bearing spans, which minimizes deflection.
* Precise hydraulic configuration made possible by the modular segmental
ring diffuser design plus numerous options.

Top of its class efficiency to ensure lowest specific power consumption per
produced cubic meter of water.
