Split Mechanical Seal MSS - Installation and maintenance instructions for machinery parts
4.0 Transport, Storage
4.1 The mechanical seal must be transported and stored in the unopened original pack-
aging. The storage site must be dry and free of dust. Influences through temperature
or irradiation must be avoided.
4. Parts or complete mechanical seals that have been dropped or otherwise subjected to
heavy impacts during transport must not be installed. An inspection by FLOWSERVE
becomes necessary.
4.3 After a storage period of three years the mechanical seal must be inspected for prop-
erties as new. This applies in particular to the secondary seals and seal faces. We
recommend an inspection by FLOWSERVE.
4.4
!
If the machine is to be preserved with integrated mechanical seal the preserving
medium must not impair the function of the mechanical seal by e. g. fouling or
hardening or swelling the secondary seals.
4.5
The mechanical seal must be transported with adequate tools, e. g. by using
industrial trucks or lifting devices.
5.0 Preparing for Installation
5.1
!
The mechanical seal may be installed when there are no visible signs of damage
to the mechanical seal. This applies in particular to the static faces of the flange,
centrings and the static sealing elements.
!
Before installing, consult the specifications on the accompanying documents to
verify that the correct mechanical seal has been installed correctly and is suitable
for the specified application. Do not exceed the design data.
!
Requisite for all assembly work are the installation drawing and parts list and the
tools and aids required for the assembly.
!
Vibrations must not be allowed to reach the installed mechanical seal when the
machine is operating or in particular when it is shut down. Vibrations can be
stopped e.g. by structural measures on the machine.
!
Installation of this seal requires the use of an adhesive to bond the O-ring second-
ary seals together. Do not allow the adhesive to come in contact with the skin.
!
The installation chamber for the mechanical seal must be checked against the
corresponding drawing and table of dimensions. It must be ensured that all
dimensions, surface qualities and tolerances (e. g. concentricity, runout, fits) are
observed.
