faces. The film lubricates the seal and prevents direct contact between the
two seal rings. This means minimum wear and long life for the seal. If the
pump runs dry, the lubricating liquid film in the seal is destroyed and wear
on the sealing rings is increased.
The mechanical seal is usually balanced. This means that it is insensitive
to the pressure in the pump. The sanitary mechanical seal needs no adjustment
and causes no wear on the shaft. It is available in single or flushed
versions
