Product Description
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.
