Pumping a fluid containing a high concentration of solids requires more than simply increasing pump capacity. Moreover, the pump structure needs to match the characteristics of the medium. This is exactly the application the KOSUN LSP Series Vertical Slurry Pump addresses.
Specifically, KOSUN developed this vertical, single-stage, single-suction cantilever centrifugal pump to transport high-solid-content fluids in oilfield, environmental, municipal and industrial applications.
Semi-Open Impeller for Solid-Containing Media
A More Open Flow Passage
The LSP Series uses a semi-open impeller.
Compared with a fully enclosed flow passage, this configuration provides a more open path for the pumped medium. As a result, it clogs less easily when handling fluids that contain solid particles.
Media the Impeller Can Handle
Consequently, the pump handles media such as mud, mortar, running sand and sludge, depending on the actual operating conditions.
Furthermore, the impeller configuration matters particularly when the pumped medium contains particles that could accumulate in restricted internal passages.
Submerged Shaft Without Bearings or Shaft Seal
Why Shaft Configuration Matters
The submerged portion of a slurry pump operates directly in the pumped medium. Therefore, its shaft configuration plays an important part in the design.
A Bearing-Free, Seal-Free Submerged Design
In the LSP Series, the pump shaft in the submerged portion offers sufficient rigidity. Additionally, KOSUN installs no bearings between the impeller and pump casing, and the design uses no shaft seal.
Thanks to this configuration, the pump transports media containing a high concentration of solid particles without relying on a shaft seal in the submerged portion.
Designed for Different Fluid Conditions
How Slurry Characteristics Vary
Slurry characteristics can vary significantly between applications. For example, drilling mud, mining slurry, municipal sludge and industrial residues may have different solid concentrations, particle characteristics and fluid properties.
Replaceable Pump Body Materials
To accommodate these varying requirements, the LSP Series allows users to replace the pump body materials according to the specific application and customer requirements.
Consequently, operators gain flexibility when configuring the pump for different operating environments.
Where Can the LSP Series Be Used?
Industries That Use the LSP Series Vertical Slurry Pump
The LSP Series applies to a range of industries, including:
- Oil drilling mud systems
- Environmental protection
- Municipal engineering
- Mining
- Thermal power generation
- Refineries
- Steel mills
- Paper mills
- Cement plants
- Coal gas coking plants
Suitable Media
Suitable media include thick liquids, heavy oil, oil residue, dirty oil, mud, mortar, running sand and flowing sludge.
How to Select the Configuration
However, users should select the actual pump configuration according to the medium characteristics and operating requirements of each project.
A Practical Solution for High-Solids Pumping
How the LSP Series Vertical Slurry Pump Works
The KOSUN LSP Series Vertical Slurry Pump combines a vertical cantilever centrifugal structure with a semi-open impeller and a submerged shaft configuration without bearings between the impeller and pump casing or a shaft seal.
Moreover, users can apply this configuration wherever a process requires transferring high-solid-content fluids — rather than limiting it to one industry.
Application Support from KOSUN
Ultimately, for drilling, mining, environmental or industrial projects, KOSUN can evaluate the pumping requirements based on the characteristics of the medium and the overall process conditions. With this support, customers can put the LSP Series Vertical Slurry Pump to work in high-solids applications with greater confidence.
