2-12 Stage Ring Sectional Centrifugal Process Pump Oil Centrifugal Pump 7.5-15m3/H

The D series Multistage Ring Section Centrifugal Process Pump is a utility-grade, high-pressure, ring section pump with heavy duty, segmental ring, diffuser design.

The pumps in a mineral processing concentrator (plant) can roughly be classified into two groups, Process pumps and Service pumps. A Service pump is any pump that provides a service to the process. A Process pump is one whose function is part of the process. The pump doing this type of job will be directly responsible for maintaining the continuous operation of the process.

These two different groups will be required to work in a variety of environments and handle various substances. This means their design and construction must change to compensate for adverse operating conditions. This could be anything from pumping Acidic or abrasive material to having to work underwater. Many of the design modifications will be limited to the material that the pump is constructed from. Such is the case in the pumping requirements of acidic chemicals and abrasive ores.

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.

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.
