Shenzhen Taimide Technology Co., Ltd

We have developed progressive cavity pump ceramic rotors that are precision-machined from high-performance engineering ceramics such as zirconia, silicon carbide or silicon nitride and are designed for progressive cavity pump systems under extreme operating conditions. The product combines the super wear resistance, corrosion resistance and lightweight characteristics of ceramic materials, which significantly improves the service life and operating efficiency of the rotor when conveying highly abrasive and corrosive media, and is an ideal alternative to traditional metal rotors.

Core Benefits:

Extremely durable

The wear resistance is increased by more than 5 times: the hardness of the ceramic rotor can reach more than HRA90, which can withstand high wear media such as particles and fibers, and reduce the attenuation of pump efficiency caused by wear.

Excellent corrosion resistance: It is inert to strong corrosive media such as acids, alkalis, salts and organic solvents, and is suitable for corrosive environments such as chemical industry, electroplating, and environmental protection wastewater treatment.

Energy-efficient

Low coefficient of friction: the surface finish of the ceramic reaches Ra≤0.1μm, the friction loss is reduced by more than 30%, the energy consumption is reduced and the pumping efficiency is improved.

Lightweight design: the density is only 40%-50% of that of steel, which reduces inertial resistance and is suitable for high-speed operation scenarios.

Precise fit

Micron-level machining accuracy: using CNC grinding and laser correction technology, the rotor shape and position tolerance is controlled within ±0.005mm, which ensures the perfect fit with the pump cavity and reduces the leakage of media.

Customized service: support customized material formulations (such as toughened zirconia, silicon carbide composites) and size specifications according to customer media characteristics, pump body structure and working conditions.

Typical areas of application

Chemical industry: transportation of highly corrosive liquids such as sulfuric acid and hydrochloric acid

Environmental protection engineering: treatment of high solid content media such as sand and sludge

Semiconductor Manufacturing: Ultra-Pure Chemical Transfer (No Risk of Metal Ion Contamination)

Food and medicine: hygienic media pumping (ceramic surface is easy to clean, no bacterial residue)
