Ceramic vs. Nonceramic Plungers

The plunger is the moving part of a pressure washer pump that travels back and forth between rubber seals to create the flow and pressure of a pressure washing system. The material that is used on all industrial-grade pumps is ceramic. This material has excellent properties that allow it to be extremely smooth — extending the life of the seals. Ceramic also does not wear. Non-ceramic plungers will wear and reduce the life of the seals.
