High Pressure 99.7% Alumina Ceramic Piston Rod for Water Jet
Cutting Machine
Tag: High pressure ceramic piston
Pistons made of alumina ceramic 99.7, Mingrui ceramics are used to
convey media ranging from liquid to high-viscosity substances. The
ceramic high-performance pistons are also exceptionally well-suited
for extreme-pressure applications, such as water-jet cutting. High
resistance to wear and optimum sliding properties ensure a long
operational lifetime.
We supply suitable materials in the required dimensions for all
individual applications.
