High purity alumina ceramic plunger

High purity alumina ceramic plunger is a high-performance industrial ceramic component.
High hardness: Alumina ceramic materials have extremely high hardness, usually reaching HRA 92 or above, ensuring their wear resistance.
High temperature resistance: capable of withstanding temperatures up to 1650 ℃ or higher, suitable for high-temperature working environments.
Corrosion resistance: It exhibits good stability in acidic media and is suitable for corrosive environments.
High mechanical strength: With high mechanical strength, it ensures stable performance in high-pressure environments.
Good insulation performance: It has a high insulation resistance and is suitable for applications that require electrical insulation.

The alumina ceramic plunger is made of high-performance technical ceramic materials and has the following detailed features:
Material composition:
99.7% Al2O3 ceramic
99% Al2O3 ceramic
95% Al2O3 ceramic
Physical performance:
Volume density: ≥ 3.9 g/cm³
Hardness: HRA ≥92
Dielectric constant: ≥ nine point seven
Maximum operating temperature:> 1650℃

Structural design:
The surface of the inner cavity adopts a fluid structure, with no dead corners or grooves, making it easy to clean and disinfect.
The clearance between the plunger rod and plunger sleeve is 2-3 microns, the cylindricity of the inner cavity is 2 microns, and the straightness is 0.1 microns, ensuring no pump jamming or leakage.
The pump body structure is finely sealed, making it easy to disassemble.

Application areas:
Widely used in industries such as ceramics, petroleum, chemical, electronics, and energy.
