Other types of tungsten carbide rotors and stators:



I. Core Mainstream Application: Progressive Cavity Pumps (Single/Double Screw Pumps) & Oil and Gas Drilling:
This is the primary application scenario for hard alloy stators and rotors, which consist of the hard alloy rotor (the rotating drive component) and the hard alloy bushing-type stator (the fixed cavity component). They replace traditional rubber stators and metal rotors to meet the demands of conveying highly abrasive, high-temperature, high-pressure, and strongly corrosive media.
Specific Equipment: Downhole oilfield progressive cavity pumps, surface progressive cavity pumps, chemical industry abrasive-resistant progressive cavity pumps, sludge/mortar progressive cavity pumps, high-pressure water injection progressive cavity pumps, downhole oil and gas screw motors/motors, rotary steerable drilling tools, wellhead high-pressure choke valves, stator-rotor pairs for agitators in chemical reaction kettles.
II. Precision Hydraulic/Pneumatic Equipment: Stator-Rotor Friction Pairs for High-Pressure Pumps, Piston Pumps, and Hydraulic Motors:
In high-pressure hydraulic transmission systems, hard alloy stators/rotors serve as core components such as valve plates, cylinder blocks, and rotor cores, enabling precise hydraulic fluid distribution and torque transmission, suitable for high-pressure, high-speed hydraulic working environments.
Specific Equipment: High-pressure axial piston pumps, radial piston pumps, hydraulic motors, servo hydraulic pumps, high-pressure grouting pumps.
III. Mining/Metallurgy Equipment: Core Stator-Rotor Components in Grinding, Classification, and Conveying Equipment:
Addressing the highly abrasive and high-impact conditions in the mining and metallurgy industry, hard alloy stators and rotors are used in equipment for grinding, classification, and material conveying to solve the rapid wear problems of traditional metal components.
Specific Equipment: Vertical spiral classifiers, mining centrifugal classifiers, rotating stators within grinding mills, stator-rotor friction pairs for slurry pumps.
