Product Description

Zrconia polished plunger mirror polished zirconia ceramic plunger shaft piston

Zirconia ceramic plungers are high-performance engineered ceramic precision components, 
manufactured from high-purity zirconia (ZrO₂) raw materials through advanced powder metallurgy processes.
Designed for chemical slurry transfer, they combine superior wear resistance with exceptional chemical inertness to endure abrasive slurries and corrosive media.
Boasting a Mohs hardness of 9 and exceptional toughness, they withstand the erosive impact of sand particles
and high-pressure fluids (up to 15,000kPa) without wear or deformation. Unlike metal plungers that require
replacement every 12-15 months, zirconia ceramic plungers extend pump overhaul intervals to 4-6 years,
slashing maintenance costs and downtime for oilfield operations.
They are trusted by top oil companies like Sinopec and CNOOC for their long-lasting wear performance.
