Tungsten Carbide Rotors and Stators

Retop supplies precision-engineered carbide rotors and stators for positive displacement motors (PDMs) and mud motors used in oil & gas drilling and high-abrasion pumping applications.

Product Description

Carbide rotors and stators are critical components in progressive cavity pumps and downhole mud motors, designed to convert hydraulic energy into mechanical torque. Made from cemented tungsten carbide, these parts offer superior abrasion, erosion, and impact resistance compared to traditional steel components. Retop manufactures custom-shaped rotors and stators with precision-ground surfaces and tight tolerances for high-efficiency sealing and torque transmission.

These components are widely used in positive displacement drilling motors (PDMs), mud pumps, artificial lift systems, and metering equipment in oil & gas, geothermal, and mining industries. Carbide stators and rotors are essential in directional drilling tools, underbalanced drilling systems, and slurry pumps, where abrasive drilling fluids, high temperatures, and extreme pressure differentials are common.
