Seal Operation
To assure reliable operation of this sealing product, the following
operating guidelines should be observed.
5.1 Maintain the gas (non-conditioned or conditioned) supply
pressure both while the seal is operating and when the equipment
is on standby. Always ensure that there is an adequate flow of
barrier gas to the seal.
5.2 Do not exceed the maximum barrier pressure specified for the
seal design. The barrier pressure should be 2 bar (25 psig) above
the operating vessel pressure.
5.3 Do not exceed the maximum vessel pressure specified for the
application. This could reduce the recommended vessel to barrier
differential pressure which could adversely affect seal performance.
5.4 Do not exceed the maximum vessel temperature specified for
the application. This could exceed the temperature limits of the seal
materials of construction applied to the application.
5.5 Do not exceed the seal material corrosion limits. This seal was
designed for the application shown on the seal assembly drawing.
Do not exceed the limits of the material alloys and elastomers
supplied in its construction.
For special problems encountered during installation, contact your
nearest Flowserve Sales and Service Representative or Flowserve
Authorized Distributor.
