Sandman^® 12 inch Tungsten Carbide Block Impeller for Mission Magnum 6x5x14 Centrifugal Pumps, the TC blocks impeller withstands the sands in drilling mud at any impingement angle.

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.

Sandman^® Centrifugal Pump Applications:

• Mud transfer, cementing, frac flowback, well-servicing, and solids control on drilling rigs (e.g. 3000m+ rigs with high-viscosity fluids).
• Slurry pumping, tailings handling, and dewatering in harsh conditions.
• Site dewatering, trench drainage, and aggregate transfer.
• Wastewater management, chemical transfer, and general fluid circulation in manufacturing.
• High-head boosting, irrigation, and flood control in remote or mobile setups.
