Product Description

Semicorex Mechanical Seal for pump offer the performance you need when looking for extended lifetime in highly aggressive fluids. Silicon carbide is a high-strength, lightweight ceramic material that is extremely hard and resistant to wear, chemicals and corrosion - even at high temperatures. These properties allow components made from Semicorex silicon carbide to withstand some of the most demanding conditions in a wide variety of industries including semiconductor, paper-making, chemical processing and oil and gas production.

The difference between SSiC and RBSiC:

1. Sintering process is different. RBSiC is to infiltrate free Si into silicon carbide at a low temperature, SSiC is formed by natural shrinkage at 2100 degrees.

2. SSiC have smoother surface, higher density and higher strength, for some sealings with more strict surface requirements, SSiC will be better.

3. Different used time under different PH and temperature, SSiC is longer than RBSiC
