Ceramic Plasma Sprayed Seal Surfaces

Mixing Impeller Shaft for Food Processing

Reason to Consider Surfacing

Worn processing equipment not only shortens equipment life but potentially can contaminate food in various stages of production.


Maintenance cost including equipment disassembly, bearings and seals along with production down time are cost and quality issues where a hard surfacing can be advantageous


A hard ceramic coating applied by either the Plasma Electric Arc System or the Rokide System produces a hard coating that is diamond ground to OEM finished specifications.


  • Increases service life 4-6 times.
  • Reduces food contamination issues from the drive side of the Impeller
  • Long term cost benefits
