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.
