BZJQB Shear Pump

BZJQB Shear Pump

BESDRILL shear pump China is mainly used to shear polymers and bentonite in mixed drilling mud. The shearing process eliminates fish eyes and prevents polymer chaining (long strings) in the mud system, which would otherwise block the shale shaker screen.

It accelerates the dilution and hydration of polymers, reduces polymer consumption, and significantly improves mud mixing efficiency.

As one of the leading shear pump manufacturers in China, BESDRILL provides high-performance shear pump solutions with competitive pricing and reliable quality.

Working Principle

BZJQB shear pump uses a high-speed impeller or rotor-stator mechanism to generate powerful shear forces.
It draws fluid in, forces it through a narrow gap, and breaks down solids, disperses particles, and emulsifies liquids — producing a homogeneous, consistent mixture.

Ideal for processing abrasive, high-viscosity, or shear-sensitive fluids in drilling, chemical, and industrial fluid applications.
