High-Performance High Pressure Mixer for Oil & Gas Drilling Fluids
Product Type: High Shear In-Line Mixer / Shearing Device
Application: Drilling mud preparation, SOBM shearing, polymer hydration, chemical dispersion
Product Overview

This advanced drilling mud mixer is engineered to handle water-based mud (WBM), oil-based mud (OBM), and synthetic oil-based mud systems. As a dedicated SOBM shearing unit, it provides superior emulsifier activation and polymer hydration under high-pressure operating conditions.
With a robust rotor-stator configuration and VFD driven shearing, this high-performance in-line mixer guarantees optimized energy transfer, consistent mixing quality, and reduced chemical wastage. The system operates efficiently within a 250–350 GPM mixer range, making it ideal for both onshore and offshore installations.
