Background
Mechanical seals comprise a "floating" part, which is mounted axially movably around the rotational axis of e.g. a pump, and a "fixed" part, which is axially fixed, typically fixed to a housing. The floating component has a flat annular end face, i.e. its sealing end face, which faces the complementary sealing end face of the fixed component. The floating component is typically urged toward the fixed component by one or more resilient members to close the seal end faces together to form a sliding face seal. In use, one of the floating member and the fixed member rotates; the component is therefore treated as a rotating component. The other of the floating and fixed components, which is referred to as the stationary component, does not rotate. Those seals in which the floating member rotates are referred to as rotary seals. If the floating member is stationary, the seal is referred to as a stationary seal.
