The new revision of our internet web has just come out and let me extend great thanks to all the firends and customers'supports at home and abroad.Dyseals has manufactured pump mechanical seals and mechanical seal faces for almost 30 years and now we can manufacture silicon carbide and ceramic bulletproof plates and body aromours and make the silicon carbide and ceramic sleeves and shafts through isostatic press and can grind the tolerance of the outside diameter to + -0.0075mm,which is a very difficult job.The tight quality control over the raw matreials of silicon carbide,ceramic and tungsten carbide is operating to ensure the quality of the final products.
