Alumina ceramic plungers are widely used in industries such as oil and gas, chemical processing, pharmaceuticals, food processing, and water treatment, etc. Typical applications include high-pressure washer pumps, metering pumps, dispensing systems, and fluid control devices.

The exceptional strength and hardness of the 99.8% alumina ceramic allows the plunger to withstand high pressure, high speed, and varying temperature conditions without deformation or failure. It can withstand the forces produced by the pump, allowing it to operate reliably at high pressures.

Features of Alumina Ceramic Plunger

Superior Wear Resistance

The abrasive nature of fluids and particles in high-pressure pumps will result in severe wear on pump components. Because of its superior wear resistance, alumina ceramic plunger can extend service life and reduce the need for frequent replacements.

Highly Resistant to Acidic and Alkaline Corrosion

The high resistance of alumina ceramic plunger to acidic and alkaline corrosion ensures that the plunger is unaffected by corrosive fluids, thereby increasing its durability and dependability.

Minimal Dimensional Changes

Alumina displays minimal dimensional changes at different temperatures, ensuring tight tolerances and consistent performance of the pump.

Tight Tolerance and Smooth Surface

Alumina ceramic plungers can be made with tight tolerances and smooth surface finishes, allowing for precise fluid metering and minimizing leakage. The surface roughness can be

FAQ About Alumina Ceramic Plunger

Q1: How does alumina ceramic compare to other ceramic plunger materials?

A: Alumina ceramic provides superior wear resistance, chemical stability, and dimensional stability, making it a popular material choice for a variety of applications. In contrast to other ceramic materials, alumina ceramic possesses a higher level of wear resistance than most ceramics, with the exception of some advanced ceramics like silicon nitride and zirconia. Moreover, it is chemically stable, although some ceramics, such as silicon carbide, may offer even greater chemical resistance. In addition, alumina ceramic provides great mechanical strength, even though zirconia exhibits higher strength and fracture toughness than it.

Q2: How to ensure proper selection and performance of the alumina plunger?

A: To ensure optimum selection and performance, please consider your application's specific requirements, for example, the operating circumstances, pressure levels, temperature ranges, and chemical exposure. Consult our technician to select the best ceramic material for your application, and any special customized requirement allowable.

Q3: How to maintain and handle alumina ceramic plungers?

A: When handling alumina ceramic plungers, it is imperative to:

• Avoid dropping or striking the plunger to prevent the possibility of breakage;
• Regularly clean the plungers to remove any contaminants or debris;
• Follow the correct installation procedures to ensure a secure and precise fitting;
• Avoid abrupt temperature changes or thermal shocks, which might harm the plunger.

Feature analysis

Alumina ceramic plungers are mostly known for their wear resistance and hardness. Long durations of high load performance are maintained by these characteristics, which lowers maintenance costs and replacement frequency. An important benefit is also their excellent temperature tolerance. Alumina ceramic plungers can provide steady and continuous functioning of some equipment that must operate in high temperature conditions. In corrosive conditions, chemical stability provides the plunger with long-term stability and lessens material corrosion and deterioration.

Process of manufacture

An alumina ceramic plunger is made via a number of careful techniques. The foundation of guaranteeing plunger performance is the selection of high-purity alumina powder. The powder is next uniformly blended by techniques like ball milling to guarantee consistency during the sintering process. Powder can be compressed into the proper plunger shape via the molding process using methods like dry pressing, isostatic pressing, or injection molding. The next stage in creating a strong and dense ceramic plunger is sintering. At last, a final product with excellent precision and surface finish is produced by means of precision machining and surface treatment.
