End face structure, product development and application of gas film mechanical seal:

After the accumulation of experience in the successful application of gas film seals on compressors, people began to try to apply gas film seals to rotary pumps and achieved the expected results. Since the 1990s, world-renowned sealing companies have successively developed a series of air-tight u0026 technical products for pumps with independent intellectual property rights. The typical end face structure of air film seal is shown in Figure 3-12.

The structural characteristics, performance and application scope of pump gas film seal products developed by several well-known international sealing companies are shown in Table 3-7.
