Mechanical Seals
Application case: zirconia pump and valve wear parts
Anonymized application case for zirconia plungers and valve components under wear and corrosion.
Status
This is a draft case. Customer approval and project data are pending; it is not published.
Approach
- Material: Y-TZP zirconia
- Parts: plungers, valve cores/seats, bushings
- Focus: roundness, cylindricity, mating clearance, roughness
- Inspection: dimensions, roundness, roughness, appearance
Challenge
Zirconia is hard and brittle; grinding and polishing must control chipping, micro-cracks and mating accuracy.
Solution
Diamond grinding and staged finishing control roundness and surface quality per mating requirements; capability to be confirmed by project.
Process
Drawing review → material confirmation → grinding/polishing → dimensional and surface inspection → packaging
