High Precision ZrO2 Zirconia Ceramic Piston

Caractéristiques de conception

Excellent material properties

High-purity zirconium oxide (more than 95%): hardness ≥1200HV, wear resistance far exceeds that of metals and ordinary ceramics.

Low friction coefficient: surface polishing to Ra≤0.1μm, reducing medium adhesion and extending the life of seals.

Precision machining technology

Nano-level precision: diameter tolerance ±0.01mm, suitable for high-precision fluid control.

Diversified structure: supports flat head, cone, multi-step design, etc., suitable for different pump body requirements.

Environmental adaptability

Corrosion resistance: acid and alkali resistance, organic solvent resistance, suitable for extreme environments with pH 1-14.

High temperature resistance: working temperature can reach 800℃ (partially stabilized formula).

Enhanced design

Fracture toughness resistance: through yttrium stabilization treatment (Y-TZP), bending strength ≥1000MPa.

Lightweight: density 6.0g/cm³, 60% lighter than metal plunger, reducing equipment energy consumption.

Domaines d’application

Medical and pharmaceutical

Medical infusion pumps, dental equipment plungers, meet the requirements of sterility and resistance to disinfectants.

Industrial high-pressure equipment

High-pressure cleaning machines, water cutting nozzles, withstand pressures above 200MPa.

Chemical and petrochemical

Metering pumps, corrosive media delivery, replace 316L stainless steel.

Food processing

Food-grade lubricating plungers, FDA-compliant, no risk of metal ion contamination.

New energy and semiconductors

Fuel cell hydrogen pumps, wafer cleaning equipment, high purity without particle shedding.
