The alumina ceramic seal rings we produce can reach up to ±0.01 in precision
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 mechanical
strength,wear-resistance, chemical resistance and air tightness.
What is more, they are water-proof when the temperature changes sharply and
can meet the requirements on sliding and sealing properties in the actual use.
They are widely used as mechanical sealing parts for metallurgy, machinery,
chemicals, medicines, food, corrosion-resistant pumps,automobiles, pneumatic
