The alumina ceramic seal rings we producecan reach up to ±0.01 in
and are suitable for mirror polishing.
They can be applied to the mechanical and motional sealing for
various types of
household, agricultural and chemical pumps due to their outstanding
strength,wear-resistance, chemical resistance and air tightness.
What is more, they are water-proof when the temperature changes
can meet the requirements on sliding and sealing properties in the
They are widely used as mechanical sealing parts for metallurgy,
chemicals, medicines, food,corrosion-resistant
