Product detail
Mascera's alumina ceramic plungers are designed for use in precision dosing and filling systems across pharmaceutical, food, cosmetic, and laboratory applications. Manufactured from high-purity Al₂O₃ (alumina) ceramic, these plungers offer excellent hardness, wear resistance, chemical inertness, and temperature stability.
Each ceramic plunger is precision-ground and mirror-polished to ensure ultra-smooth surface finish, making it ideal for use in metering systems requiring tight tolerances and repeatable performance. Available in various diameters and lengths, our plungers can be fully customized based on drawings or OEM specifications.
Whether for new builds or replacing existing metal or ceramic plungers, Mascera's alumina ceramic plungers provide an optimal solution for high-performance, long-lifespan pump components.
