The TRJQB Series shear pump is a high-shear pump for drilling fluid and mud processing systems. It applies strong shear forces to bentonite, polymers, clay and other drilling additives, breaking up agglomerates and dispersing them evenly through the fluid. This promotes faster hydration and more uniform mud properties.
The shear pump is installed with mud tanks, jet mud hoppers and other solids control equipment in drilling fluid systems. The hopper introduces dry additives into the fluid stream, while the pump provides the shear energy to break and hydrate the material. Together they form a complete drilling fluid preparation system.
High Shear Mixing Performance
Strong shear forces quickly disperse bentonite, polymers, and other drilling fluid additives for better mixing results.
Efficient Polymer Hydration
Faster polymer wetting and hydration improve mud preparation efficiency.
Reduced Bentonite Consumption
Optimized additive dispersion cuts bentonite consumption by more than 30%.
Lower Mud Loss
Improved mud preparation reduces unnecessary drilling fluid loss and material waste.
Full Mechanical Seal
Full mechanical sealing design prevents leakage and enables reliable continuous operation.
Durable Construction
Heavy-duty components provide longer service life in demanding drilling environments.
Drilling fluid enters the pump through the suction inlet. The rotating impeller accelerates the fluid through the shear zone between the impeller and stationary components.
The generated shear forces and turbulence break down additive agglomerates and improve the dispersion of bentonite, polymers, and other drilling fluid additives.
When integrated with a jet mud mixing hopper, the shear pump provides the circulation and high shear required for efficient additive mixing and hydration.

Oil & Gas Drilling
Deployed for drilling fluid preparation with bentonite, polymers and chemical additives. Enhances additive dispersion and mud consistency during mixing.
HDD Mud Systems
Facilitates mud preparation for horizontal directional drilling, providing consistent drilling fluid quality before circulation.
TBM and Tunnel Slurry Systems
Used with slurry mixing systems to prepare bentonite- and polymer-based slurry for tunneling and ground support.
Bored Pile and Foundation Drilling
Used for slurry preparation in foundation projects requiring stable rheology and reliable borehole support.
Match Pump Capacity to Mud System
Select the shear pump based on required flow rate, discharge head, and mud preparation capacity. Proper sizing maintains efficient operation while avoiding unnecessary power consumption.
Check Installation Requirements
Consider power supply, piping layout and installation space before selecting a model. TR provides suitable pump configurations for different operating conditions.
Integrate with Mud Mixing Equipment
For systems using a jet mud hopper, match hopper capacity to pump output for stable additive feeding and efficient mud preparation.

What is a shear pump used for in drilling?
Mud shear pump is used for drilling fluid preparation. It delivers high-shear mixing action to disperse bentonite, polymers, and other additives more efficiently.
Can a shear pump reduce bentonite consumption?
Improved shearing and additive dispersion can increase bentonite utilization. Actual savings depend on mud formulation, material properties, and operating conditions.
Does drilling fluid shear pump replace a mud agitator?
No. A shear pump conditions drilling fluid during mud preparation, while a mud agitator keeps solids suspended and prevents settling in the mud tank.
We manufacture TRJQB Series shear pumps for drilling fluid preparation and mud mixing systems. Our factory handles equipment design, fabrication, assembly and performance testing before delivery.
Shear pumps are available as standalone units or integrated with jet mud hoppers and other drilling fluid equipment. Pump selection is based on flow rate, lift, motor requirements and project conditions.
We also offer customized mud preparation equipment and complete drilling fluid system solutions for oil and gas drilling, HDD, tunneling and slurry-based construction projects.
