4. Transport, Storage
The mechanical seal and related equipment maust be transported and
stored in the unopened, original shipping box. The warehouse in which
the mechanical seals and related equipment are stored must be dry and
free of dust. Avoid exposing equipment to large temperature fluctua-
tions and radiation.
Parts or complete mechanical seals that have been dropped or other-
wise have been subjected to heavy impacts during transport must not
be installed.
An inspection by Flowserve or its appointed representative is strongly
advised.
If the machine is to be preserved with integrated mechanical
seal(s) the preserving medium must not impair the functions of
the mechanical seal(s) by e.g. fouling of the seal faces, hardening,
or swelling the secondary seals.
After a storage period of 3 years the mechanical seal must be inspect-
ed for its “as new” properties. This applies in particular to the seal
faces and secondary sealing elements. An inspection by Flowserve
becomes necessary.
!
The mechanical seal can in principle be transported with suitable
means like lifting accessories.
