In remote overseas drilling sites, the reliability and efficiency of solids control equipment directly impact Non-Productive Time (NPT). Designed for high-intensity operations, the KOSUN SP series drilling mud shear pump achieves an optimal balance between high-efficiency shearing and long-term durability through deep hydrodynamic optimization. It has become the preferred solution for major oil and gas projects worldwide.

Hydrodynamic Design: Axial Turbine and Pressure Chambers
Unlike the simple construction of traditional centrifugal pumps, the SP series drilling mud shear pump integrates a complex structure consisting of an axial turbine, a fluid reservoir, and a specialized pressure chamber. As fluid enters the pump, it gains axial acceleration through the turbine zone before accumulating kinetic energy within the pressure chamber. When the fluid is ejected against the shearing plate via high-pressure nozzles, the resulting intense turbulence and mechanical impact instantly crush insoluble polymer agglomerates. This ensures high homogeneity of the fluid in a single circulation.
Enhanced Wear Resistance via Stainless Steel Precision Casting
Solid particles in drilling fluids are highly erosive to flow-passing components. To address this challenge, the critical impeller components of the KOSUN drilling mud shear pump are manufactured using stainless steel precision casting. Compared to the common cast iron materials used in the industry, stainless steel impellers offer superior wear and corrosion resistance. This is particularly vital when handling highly corrosive or high-sand-content mud, significantly extending maintenance cycles and reducing the frequency of spare parts replacement.
Low NPSH for Stability in Complex Conditions
During field operations, fluctuations in mud tank levels or rising mud temperatures can easily cause cavitation in pumping equipment. The engineering design of the KOSUN drilling mud shear pump ensures stable operation even under low-pressure suction environments. By minimizing cavitation, the system avoids vibration damage to mechanical seals and bearings, thereby increasing the overall operational redundancy of the solids control system.
High ROI Proven by Global Projects
The KOSUN SP series drilling mud shear pump has been deployed on drilling rigs across extreme environments, including the Middle East and Russia. Field data indicates that with a 75kW power configuration, the pump delivers a processing capacity of up to 150 m³/h. Its high shearing conversion rate not only optimizes mud performance but also helps contractors recover equipment investment costs quickly by reducing chemical additive consumption, achieving leadership in both performance and economic efficiency.
Maintenance Convenience Aligned with International Standards
Strictly designed in accordance with API industry standards, the KOSUN drilling mud shear pump features a compact structure that is easy to maintain on-site. Its universal seal design considers the global availability of spare parts, minimizing equipment downtime caused by repairs. For overseas projects seeking long-term stable operations, these field-optimized engineering details represent the core competitive advantage.
