The KSMR Series HDD mud recycling system from KOSUN is specifically engineered to improve drilling efficiency, reduce waste, and lower operational costs in horizontal directional drilling (HDD), geothermal, and resource extraction projects. 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 are specifically designed for small HDD, geothermal, and water well drilling projects where space is limited and portability matters. 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.
Built for Reliability and International Standards
KSMR systems are built for demanding drilling environments. Every unit features explosion-proof, dust-proof, and rain-proof electrical systems, ensuring safe and reliable operation in harsh conditions — from dusty desert sites to wet coastal locations. Certified by API, CE, and ISO14001 international standards, the KSMR series meets global safety and environmental requirements, making them suitable for export and use in regulated markets worldwide. When you choose KOSUN, you are choosing equipment that is tested, certified, and ready to work.
From the lightweight KSMR-200 to the large-capacity KSMR-1000, KOSUN HDD mud recycling systems resolve the conflict between "space and efficiency" through finely tiered technical solutions. By selecting the appropriate model, customers can achieve both optimization of construction costs and compliance with environmental standards.
