High-Intensity Shearing for Drilling Fluid Systems

Effective drilling fluid preparation requires more than simply combining chemicals and base fluids. Additives must be properly dispersed and activated to achieve the required fluid performance.

The PP-800LS High Shear In-Line Mixer uses a precision rotor-stator assembly to generate high-intensity shear. The 8-bladed Sverker rotor works with a 3 mm fine-slotted Sverker head to provide controlled mechanical shearing and uniform dispersion.

This configuration supports rapid polymer wetting and hydration while improving the dispersion of drilling fluid chemicals. For oil-based and synthetic systems, the shearing action can also support emulsifier activation and consistent fluid processing.

VFD-Driven Shearing for Better Process Control

One of the important features of the PP-800LS High Shear In-Line Mixer is its VFD-driven shearing capability. The system uses a 120 HP (90 kW) motor with a 300 RPM base speed and can operate at approximately 4500 RPM through a frequency inverter.

Variable-speed operation allows operators to adjust shear intensity according to fluid characteristics and processing requirements. This provides greater flexibility when working with different drilling mud formulations and can help optimize energy use and mixing performance.

The motor is supplied with a TEFC/IP55 enclosure and operates on a 400 V, three-phase, 50 Hz electrical supply. VFD operation is optional according to the specified configuration.

Designed as a High Pressure Mixer for Oilfield Applications

The PP-800LS is engineered for demanding oilfield environments and provides operating capacity of approximately 250–350 GPM, depending on fluid properties. It is suitable for pressures up to 100 psi, with a typical differential pressure of approximately 40 psi.

Its horizontal direct in-line entry configuration, combined with 4-inch ASA flanged inlet and outlet connections, allows integration into existing drilling fluid processing systems.

As a high pressure mixer for oilfield operations, the unit is suitable for continuous processing where reliable fluid movement, controlled shearing, and efficient chemical dispersion are required.

Robust Construction for Demanding Drilling Environments

Durability is essential when mixing abrasive drilling fluids and handling chemical additives. The PP-800LS features SS 316L product-contact components, providing corrosion resistance in demanding chemical environments.

The mixer incorporates a single Tungsten Carbide mechanical shaft seal designed for abrasive drilling mud applications. Its structural design includes a transparent neck cover for inspection, a threaded elbow at the base, a dowelled front plate for alignment, and a coated mild-steel base frame.

These engineering features support dependable operation while allowing practical inspection and maintenance.

Applications of the PP-800LS High Shear In-Line Mixer

The PP-800LS High Shear In-Line Mixer can be incorporated into several drilling fluid preparation and processing applications, including:

• Drilling mud preparation and conditioning
• WBM mixing and chemical dispersion
• OBM processing
• SOBM shearing and emulsifier activation
• Polymer hydration and viscosifier preparation
• Chemical dispersion in mud systems
• Bulk mud plant operations
• Continuous drilling fluid processing
• Polymer hydration modules
• Chemical injection skids

Its 250–350 GPM processing range makes the unit particularly suitable for larger-scale mud preparation systems where continuous operation is required.

Why Efficient Polymer Hydration Matters

Polymers are commonly used in drilling fluids to influence viscosity, filtration control, suspension, and other fluid properties. However, the effectiveness of a polymer depends significantly on proper wetting, dispersion, and hydration.

The PP-800LS provides high-intensity shear that promotes rapid polymer wetting and hydration. Better dispersion can help reduce localized concentrations and improve the consistency of the prepared drilling fluid.

This makes the unit a valuable drilling mud mixer for operations where efficient additive utilization and reliable fluid preparation are important.

Standard Supply and Maintenance Support

The PP-800LS is supplied as a complete mixer assembly with a rotor removal tool, stator removal tool, base-mounted channel frame, and pre-installed mechanical shaft seal.

Including dedicated removal tools helps simplify maintenance activities and supports easier access to critical mixer components. Regular inspection and appropriate maintenance remain important for maintaining performance, particularly when processing abrasive drilling fluids.
