With over 20 years of solids control expertise, KOSUN delivers reliable mud cleaning, recovery, mixing, and storage solutions for projects ranging from 200 to 1000 GPM capacity. Whether you are laying pipeline under a city or drilling a water well in a remote location, the KSMR series provides the performance you need.

Compact and Efficient Design for Small to Medium Projects

The KSMR-200 and KSMR-350 models target small HDD, geothermal, and water well drilling projects that require compact, easily portable equipment. Equipped with double-deck shale shakers, these systems achieve two-stage solids separation in an exceptionally compact footprint. This integrated design makes them easy to transport between job sites and allows them to operate effectively in tight urban workspaces where larger equipment simply cannot fit. Despite their small size, these mud recycling systems deliver powerful solids control that keeps drilling fluid clean and project costs under control.

Advanced Multi-Stage Purification for Demanding Operations

For medium and large drilling operations, the KSMR-500 and KSMR-1000 offer advanced three-stage purification using a combination of shale shakers, desander cyclones, and desilter cyclones. This multi-stage approach progressively removes finer and finer solids from the drilling fluid, resulting in superior mud quality that enhances drilling performance. The KSMR-500 is ideal for projects up to 500 GPM , while the KSMR-1000 handles the most demanding large-scale HDD and coalbed methane operations with ease. By maintaining stable mud properties even during continuous, high-volume drilling, these systems reduce waste discharge, lower additive consumption, and extend the life of downstream equipment.

Integrated Mud Mixing System for Closed-Loop Recycling

The KSMR series includes an efficient mud mixing system that quickly restores drilling fluid properties by evenly mixing additives such as bentonite and polymers. After the mud undergoes multi-stage purification, the mixing system allows operators to adjust viscosity, density, and other key parameters to match specific formation requirements. This closed-loop recycling process significantly reduces fresh water usage, minimizes waste volume, and lowers the overall environmental footprint of the drilling operation. Less water to buy, less waste to haul, and better drilling performance — that is the KSMR advantage.

Mud purification equipment, also known as a mud purification unit, combines two different mud purification methods — mud shale shaker and cyclone separation — to effectively purify drilling mud. For construction projects ranging from pile driving and diaphragm walls to trenchless HDD and shield tunneling, selecting the right equipment is essential for controlling costs, protecting the environment, and keeping the job moving efficiently. KOSUN is a leading manufacturer specializing in this technology.

Why Mud Purification Matters

During drilling operations, mud becomes contaminated with rock cuttings, sand, and other solids. If left untreated, dirty mud loses its ability to cool the bit, lubricate the drill string, and maintain borehole stability. The result is slower drilling, higher equipment wear, and increased risk of costly problems. Mud purification equipment solves this by removing harmful solids and returning clean mud to the circulation system.

Key Advantages of Quality Mud Purification Equipment

What makes good mud purification equipment stand out? Let us look at the key advantages.

1. Compact Design

By combining double-layer vibrating screens and cyclones into a single unit, modern mud purification equipment takes up minimal space on crowded job sites. A smaller footprint means easier transport, simpler setup, and more room for other equipment.

2. Strong Processing Capability

Quality equipment can quickly handle particles from 15μm to 44μm, removing fine solids that damage pumps and downhole tools. By enabling mud reuse, this capability significantly reduces operational costs — less new mud to buy, less waste to haul away.

3. Durability

The screens and cyclones are made of new wear-resistant materials, ensuring long service life even in abrasive drilling conditions. Less downtime for maintenance means more reliable performance.

4. Environmental Compliance

Mud treated by the equipment’s mud recycling system can be reused repeatedly, significantly reducing environmental pollution. By minimizing waste discharge, mud purification equipment helps projects meet strict regulations and avoid costly fines.

How Equipment Works

Contaminated mud first passes through the mud shale shaker , which removes larger cuttings using high-frequency vibration. The mud then flows to the cyclone separation stage, where centrifugal force removes finer particles down to the 15–44 micron range. This two-stage approach — shaker plus cyclones — is what makes the mud purification unit so effective.

Conclusion

In conclusion, choosing the right mud purification equipment comes down to four key factors: compact design for tight spaces, strong processing capability for 15–44μm removal, durable wear-resistant materials, and environmental compliance. Get these right, and your mud system will run cleaner, longer, and more cost-effectively. KOSUN is committed to providing high-performance mud purification solutions tailored to your project needs.

In drilling fluid management, two critical pieces of equipment serve as the first lines of defense in solids control: the shale shaker and the desander. For newcomers and experienced professionals alike, the differences between these two machines can sometimes be unclear. Both are essential components of a solids control system, which removes drilled solids from drilling fluid (mud). This mud plays a vital role in lubricating the drill bit, maintaining wellbore pressure, and transporting cuttings to the surface. Inefficient solids removal can increase drilling costs, accelerate equipment wear, and create wellbore stability issues.

Although they share the same goal, shale shakers and desanders work on different principles and target different particle sizes. Understanding their roles, capabilities, and positions in the processing sequence is essential for improving drilling efficiency, safety, and cost control. KOSUN provides high-performance shale shakers and desanders designed for integrated solids control solutions.

The Primary Function and Operating Principle

The key difference between the two lies in their separation methods. A shale shaker is a screening device that uses vibrating screens with specific mesh sizes to separate solids based on particle size. Drilling fluid flows onto the vibrating screen deck, where liquid and smaller particles pass through, while larger solids are transported off the screen and discarded. It is a direct mechanical filtration process.

A desander, however, uses centrifugal separation through hydrocyclones. When fluid enters the cone-shaped hydrocyclone tangentially, rapid rotation creates centrifugal forces that push heavier solids outward and downward for discharge through the apex. Meanwhile, cleaner fluid exits through the vortex finder at the top.

Particle Size Removal and Efficiency

Their different operating principles determine the particle sizes they remove. The shale shaker is the first stage of solids control and handles large-volume cuttings, typically removing solids larger than 74 microns (200 mesh), although finer screens can be used for more demanding applications.

The desander is a secondary cleaning device designed to remove smaller abrasive sand particles, generally in the range of 45–74 microns. It processes fluid that has already passed through the shaker and removes solids that could cause wear in downstream equipment. KOSUN desanders are engineered for efficient sand removal and enhanced equipment protection.

Placement in the Solids Control System

The equipment sequence is carefully designed for maximum efficiency. Drilling fluid returning from the wellbore always enters the shale shaker first. As the primary solids control device, the shaker processes the full mud flow and removes the largest cuttings.

The fluid that passes through the shaker screens collects in the mud tank and is then pumped to the desander. Unlike the shaker, the desander does not process the entire incoming mud stream; it only treats pre-cleaned fluid. After desanding, the mud may continue to a desilter and degasser before being returned to the well. KOSUN integrated solids control systems ensure smooth coordination between each processing stage.

Key Design and Operational Characteristics

A shale shaker is identified by its vibrating screen deck, which may use linear or elliptical motion, powered by electric or hydraulic motors. Its main operating factor is the screen mesh size, which determines the separation point.

A desander consists of hydrocyclone cones mounted above a dedicated tank. It requires a separate pump to provide the pressure and flow needed to generate the vortex inside the cones. The main design factor is hydrocyclone diameter; typically, 10-inch cones are used for desanders, while smaller cones are used for desilters.

How They Work Together for Efficient Solids Control

Shale shakers and desanders are not competing technologies — they are complementary parts of the solids control process. The shaker works as a coarse filter, protecting the desander from large solids that could block or damage its hydrocyclones. The desander then removes finer abrasive particles that can accelerate wear on pumps, drill bits, and other equipment.

Ignoring either stage can reduce system performance. Without a shaker, the desander can quickly become overloaded, while operating without a desander may result in excessive equipment wear and poor drilling fluid quality. Their combined operation helps maintain a clean, stable, and efficient drilling fluid system.

Conclusion

In modern drilling operations, choosing between a shale shaker and a desander is not necessary — an effective solids control system requires both. The shaker removes bulk solids, while the desander captures finer abrasive particles. Together, they protect equipment, maintain drilling fluid properties, and improve overall drilling performance.

KOSUN offers both shale shakers and desanders, providing integrated solutions for efficient and reliable solids control systems.

One of the most adaptable and widely used fluid handling technologies across industries is the centrifugal pump.

Due to deeper wells and higher pressure formations, shale operations often require pumps with higher head capabilities and long-term operating stability.

Remote drilling locations make pump reliability and maintenance especially important. Modern centrifugal pumps for shale applications include replaceable wear components and simplified maintenance systems to reduce downtime. Efficient pump designs also help lower energy consumption, operating costs, and fluid leakage risks.

Geothermal Well Drilling and Maintenance

The development of geothermal energy requires pumping systems capable of handling high-temperature fluids and corrosive geothermal brines. Centrifugal pumps used in geothermal applications must maintain performance under extreme temperatures and challenging chemical conditions.

The unique properties of geothermal fluids can affect impeller durability and shaft seal performance. Anti-clogging designs, corrosion-resistant materials, and reliable flow control are essential for applications such as production testing, chemical injection, and circulation cleaning. KOSUN geothermal pumping systems are designed to withstand these demanding operating environments.

Directional Drilling for Urban Infrastructure

Directional drilling has become increasingly important for installing underground utilities while minimizing surface disruption. In these compact environments, centrifugal pumps support bentonite mixing, drilling mud circulation, and hole cleaning operations.

Urban projects often require low-noise, low-vibration equipment due to nearby buildings and strict regulations. Modern centrifugal pumps use improved bearing designs and vibration reduction systems to minimize operational disturbance. Compact, high-efficiency pump solutions help meet the space limitations of urban construction projects.

Deepwater Exploration Vessels

Deepwater exploration vessels require some of the most advanced pumping systems available. Operating in extremely deep waters creates challenges related to suction conditions, pressure levels, and long pipeline distances. Advanced hydraulic designs help maintain proper NPSH (Net Positive Suction Head), preventing cavitation and ensuring reliable operation.

Because equipment failures can cause significant financial losses, deepwater vessels require highly reliable and redundant pump systems. Backup configurations and automated controls help maintain continuous operation during maintenance. Pump integration must also coordinate with vessel positioning and motion control systems.

Mining Core Sampling Operations

Mining exploration relies on core sampling programs to evaluate resources and support extraction planning. Centrifugal pumps assist these operations by providing drilling fluid circulation, sample cleaning, and waste management.

Mining environments expose pumps to abrasive materials, requiring wear-resistant impellers, casings, and protected bearings. Remote mining locations also demand flexible power solutions, including diesel-powered pump systems where grid electricity is unavailable. Accurate flow control helps maintain sample quality and improve recovery results.

Environmental Remediation Drilling

Environmental remediation projects use specialized drilling techniques to treat contaminated soil and groundwater. Centrifugal pumps play an important role in handling polluted fluids, chemical injection, and waste processing.

These applications require careful pump selection to prevent cavitation and safely manage hazardous substances. Double mechanical seals, leak detection systems, and containment solutions help maintain environmental protection. Pump performance must also adapt to changing fluid characteristics throughout the cleanup process.

Conclusion
