If leakage from the blower is not permitted because, for example, special gases are being handled, leaks become an issue, especially from the shaft though-hole section. The photograph shows an airtight-type blower in which a water-lubricated double mechanical seal is used for the shaft seal. We can build blowers with different kinds of shaft seals for your required application.
