Silicon carbide mechanical seal：Ceramic sealing ring

In many industries, when it comes to sealing materials, people usually consider several issues, such as sealing, wear resistance and corrosion resistance. Especially in harsh environments, the service life of ordinary materials is a big problem. In the field of advanced materials, a material has emerged that solves the dilemma of traditional sealing materials in industries that require high-performance sealing. This material is Siliziumkarbid.

What is a Silicon Carbide

Silicon carbide (SIC) is a material second only to diamond in hardness. Even in high temperature environments, it has good corrosion resistance and wear resistance and has a long service life.

Gute Gleiteigenschaften
Ungiftig und umweltverträglich
Die zweithöchste Härte nach Diamant
Ausgezeichnete Temperaturwechselbeständigkeit (ΔT = 1.100 K)
Korrosions- und verschleißfest auch bei hohen Temperaturen

The relationship between mechanical seals and silicon carbide
SiC mechanical seals typically consist of two parts: a seal face (the rotating part) and a counterface (the stationary part), both made from reaction-bonded silicon carbide. This combination ensures excellent sealing performance under extreme conditions.

Applications of Silicon Carbide Mechanical Seals

Chemical Processing

In chemical plants, where fluid leakage can cause contamination, equipment failure, or hazardous conditions, SiC mechanical seals provide the reliability needed for critical operations, including mixers, pumps, and reactors.

Water Treatment

SiC seals are widely used in water treatment plants where chemical resistance and high mechanical strength are required to handle aggressive cleaning agents and harsh operational environments.

Luft- und Raumfahrt und Verteidigung

In the aerospace industry, silicon carbide seals are used in applications where high precision, low friction, and high temperature tolerance are essential, including turbines and engine components.

Oil and Gas

Mechanical seals made from Siliziumkarbid are employed in pumps and compressors that handle corrosive fluids and operate in extreme environments, such as offshore drilling rigs and refineries.

Food and Beverage

In the food and beverage industry, SiC seals ensure hygiene by preventing contamination, especially in equipment used for processing and packaging.
