Alumina Plungers

Plungers with metal inserts for reciprocating plunger pumps
Plungers with metal inserts can be secured by shrink fitting and / or gluing

Demanding applications such as conveying abrasive fluids using high-pressure pumps or precise fluid metering require special components. Typical areas of application are:

  • High pressure pump systems
  • Industrial cleaning
  • Process pumps in chemical industries

In such applications plungers are central to the pumps mechanism and are often subject to high rod loads. Our ceramic plungers offer numerous advantages over commercially available metal plungers. Excellent service life and operating times are possible with our plungers due to their high wear and corrosion resistance.

The tribological properties of alumina ceramics allow the plunger to run with low friction and high energy efficiency. Further, dimensional and temperature stability allows operation at all operating temperatures while maintaining dimensional tolerances.

Ceramic plungers are available in a wide range of standard sizes and can also be custom designed to meet the demands of your application.
