Product Description

FreeWill Material technical ceramic product families and engineering applications

Ceramic sleeves, liners and guiding bushings for metering pumps and precision fluid-handling assemblies.

Ceramic pump bushings include guide sleeves and liners that support a moving plunger, shaft or other fluid-control component.

A hard ceramic bore provides a wear-resistant guide or fluid-contact surface, helping preserve the moving component’s alignment.

Product Features

  • Precision Bore
  • Wear Guidance
  • Grade-dependent chemical resistance
  • Matched Clearance

Typical Applications

  • Metering Pumps — Plunger guides, sleeves and cylinder liners: Supports controlled alignment and wear surfaces.
  • Chemical Processing — Fluid-contact pump components: Provides material options for reviewed media and cleaning conditions.
