Tungsten carbide ring for mechanical seal

Product Details:

  • Mediums to be sealed: water, oil, corrosion, other mediums including solid granule,
  • Working environment: resisting abrasion, acid, alkali and erosion;
  • Working temperature: from -30℃ to 500℃
  • Application: pump, valv

The material grade of tungsten carbide:

  • Material advantage: the usage life of our all material is better than the silicon carbide.
  • The price of MG1 is similar with silicon carbide, but the transverse rupture strength is stronger, not easier to break in the working.
