Ceramic materials compose pump components such as liners, plungers, cylinder walls, balls and impellers, which are in contact with abrasive or corrosive media (e.g., liquids, slurries, hot gases). Sliding components within the drive portion of the pump also benefit from the low friction, tight tolerances and the ability to run dry or without lubrication. Ceramics are brittle, low-toughness materials, so plastic or metal housings and backings are used behind the ceramic components for support and durability.
