1.2 Brief Description
A mechanical seal is a device designed to seal a rotating shaft
against a stationary housing, e.g. a pump shaft against a pump
casing. The stationary components will consist of a seal ring
and (depending on the design) a spring-loaded element. The
spring-loaded element can be a spring or a bellows. The seal ring
is sealed against the housing with a secondary gasket, e.g. an
O-ring. The rotating components will consist of a seal ring and
(depending on the design) a spring-loaded element. The spring-
loaded element can be a spring or a bellows.
The seal ring is sealed against the shaft with a secondary gasket,
e.g. an O-ring.
A mechanical seal can be supplied as a pre-assembled cartridge
or in separate components. Assembly is done in accordance with
the assembly drawing.
A mechanical seal will run in the pumped product or external
source fluid.
