Sandman® Supreme Shear Pump Impeller with Tungsten Carbide chips adhered to the face to givea rough surface, exerts a mechanical shearing effect on the conveyed solids.

The shear pump is primarily designed for the shear treatment of drilling cuttings. By harnessing the pump’s operational power, when the velocity of the conveyed fluid exceeds a specific threshold, liquid shear occurs between the solid particles. Furthermore, when the shearing of solids is required, allowing the solids to drag against the impeller blades generates mechanical shear, thereby achieving the objective of reduce the size of solids.

Sandman^® Mission centrifugal pumps are high-performance pumps widely used in oil and gas drilling, mud circulation, frac operations, and abrasive slurry handling. The impeller with tungsten carbide block coating refers to a thermal-sprayed protective layer of tungsten carbide applied to the impeller surface, forming a hard, dense barrier against erosion, abrasion, cavitation, and corrosion. This block style contain the rough hard solids, rather than embedded inserts, providing gas-tight protection even at thin thicknesses.
The TC coatings extend impeller life by 3-5 times in abrasive conditions, reducing downtime and maintenance costs.

Sandman^® Mission Pump TC Coating Parts Advantages:

• Erosion and Abrasion Resistance: Withstands high-velocity particles (e.g., sand in drilling mud) at any impingement angle.
• Cavitation Protection: Dense coating prevents pitting from vapor bubble collapse.
• Corrosion Barrier: Non-porous layer shields base metal (e.g., ductile iron or hard iron) from pH 7–14 fluids.
• Durability: Improve the hardness.
• Compatibility: Available for Mission Magnum series (including 3x2x13, 4x3x13, 6x5x11, 8x6x14, 10x8x14, 14x12x22), which feature semi-open or open impellers for solids handling.
