Performance and characteristics of zirconia ceramic plunger


지르코니아 세라믹 플런저, as the core components of modern industry, are gradually replacing traditional metal and plastic plungers with their excellent physical and chemical properties, becoming the preferred solution for high-precision, high wear resistance, and high corrosion resistance working conditions.

Performance and characteristics of zirconia ceramic plunger

Core performance: derived from the excellent characteristics of zirconia materials
Zirconia ceramics, especially yttrium stabilized zirconia, are an advanced structural ceramic. It endows the plunger with performance far beyond conventional materials:

  1. Extremely high wear resistance: Zirconia has a Rockwell hardness of HRA85 or higher, second only to diamond and silicon carbide. This means that it can exhibit extremely low wear rates when worn against metal, plastic, or other materials, and its service life is 5-10 times longer than that of traditional GCr15 bearing steel plungers.
  2. 내식성이 뛰어납니다: Zirconia is an inert material that can withstand the corrosion of most chemical media such as acids, alkalis, salts, etc., without producing rust. This perfectly solves the problem of metal materials being easily corroded and contaminated in corrosive media.
  3. 높은 강도와 견고함: Through phase transformation toughening technology, the bending strength and fracture toughness of oxide ceramics rank among the top in engineering ceramics, and can withstand high working pressure and impact loads, effectively overcoming the inherent impression of ceramic fragility.
  4. 자체 윤활 및 낮은 마찰 계수: After polishing treatment, the surface of the zirconia plunger can achieve a mirror effect (Ra<0.2 μ m), and the friction coefficient is extremely low. When combined with sealing components made of polymer materials such as polytetrafluoroethylene and ultra-high molecular weight polyethylene, smooth operation can be achieved, reducing frictional heat and power loss.
  5. Non magnetic and insulating: Zirconia is non-magnetic and non-conductive, suitable for special application environments that are sensitive to magnetic fields or require electrical insulation.

Product advantage: Direct value brought to industrial applications
Based on the above performance, zirconia ceramic plungers exhibit significant comprehensive advantages:
Long lifespan, cost reduction and efficiency improvement: The extremely low wear rate significantly extends the replacement cycle of the plunger and its paired seals, reduces equipment downtime and maintenance costs, and has significant overall economic benefits.
High stability and quality assurance: Its high hardness and low thermal expansion coefficient ensure the dimensional stability of the plunger under temperature differences, thereby ensuring measurement and conveying accuracy, which is crucial for processes that require precise proportioning and stable fluids.
Clean and pollution-free, meeting strict standards: no rust, no metal ion precipitation, and a smooth surface that does not adsorb materials. It is very suitable for industries such as food, medicine, and biotechnology that require extremely high cleanliness.
Energy saving and environmental protection: Low friction coefficient means a reduction in driving power, which helps equipment save energy. Meanwhile, its long lifespan also reduces waste generation, in line with the concept of green manufacturing.

Performance and characteristics of zirconia ceramic plunger

Problem solved: Accurately addressing industry pain points
The birth and application of zirconia ceramic plungers effectively solve the core pain points of traditional plungers in various scenarios:
To solve the problem of wear and leakage: In high-pressure water pump, spray granulation and other equipment, rapid wear of metal plunger will lead to seal failure, pressure drop and fluid leakage. The wear resistance of zirconia plungers fundamentally solves this problem.
Addressing corrosion and pollution issues: In chemical metering pumps and electroplating solution delivery pumps, metal plungers can be corroded by corrosive media, causing not only self damage but also chemical pollution. The corrosion resistance of zirconia ensures the purity of the fluid and the durability of the equipment.
Addressing accuracy and stability issues: In high-end analytical instruments and liquid chromatographs, even minor wear or size changes of the plunger can lead to measurement inaccuracies. The dimensional stability and wear resistance of zirconia plungers ensure the accuracy of long-term operation.

일반적인 애플리케이션 시나리오
The performance advantages of zirconia ceramic plungers have been fully validated in the following fields:

  1. High pressure cleaning and water jet equipment: As the core boosting component, it can withstand working pressures of hundreds of megapascals, and its wear resistance ensures long-term stable high-pressure output.
  2. spray granulation and drying equipment (such as the preparation of milk powder and ceramic powder): the slurry is transported in a high-pressure pump, which is wear-resistant and corrosion resistant, to ensure uniform atomization and product consistency.
  3. Chemical and petroleum fields: used for metering pumps, plug pumps, precise transportation of corrosive solvents, acidic and alkaline fluids, drilling mud, etc.
  4. 식품 및 제약 산업: In filling machines, homogenizers, infusion pumps, their clean and non-toxic characteristics comply with FDA, GMP and other standards, and are used for conveying sauces, drugs, culture media, etc.
  5. Analytical instruments and laboratory equipment: As a high-precision infusion pump plunger for liquid chromatography and biochemical analyzers, it provides stable and low pulsation fluid delivery.
