99.5% Alumina Ceramic Tube Insulation Chemical Corrosion Resistant
The majority of the ceramic pump liners manufactured by Mingrui are
of a two part design. The inner sleeve is produced from either
Zirconia (ZrO3) or Alumina (Al2O3).
The performance of Alumina in terms of wear life far exceeds that
of traditional “chrome” liners. Zirconia has proven to have better
impact strength, is harder, and can be honed to a finer surface
finish than Alumina. The outer casing is produced from steel or
stainless steel.
