Dual Gas Barrier Seals - Installation and Mintenance Instructions for Machinery Components
dance with plant regulations, but should not create additional danger. These
guards have to ensure proper access to the working area required for mainte-
nance to the mechanical seal.
The electricity supply of the equipment must be in accordance with directive
2006/95/EC. When machinery is powered by a source of energy other than
electricity this may not cause dangerous situations for persons and environ-
ment.
3. General
All illustrations and details in these installation instructions are subject to changes
that are necessary to improve product performance without prior notice.
The copyright of these instructions is the property of Flowserve. These instructions
are intended for Maintenance, Operating and Supervisory personnel and contain

It should be understood that Flowserve does not accept any liability for
instances of damage and/or malfunctioning incurred through non-adherence
to these installation instructions.
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 equip-
ment to large temperature fluctuations and radiation.
Parts or complete mechanical seals that have been dropped or otherwise have been
subjected to heavy impacts during transport must not be installed.
An inspection by Flowserve or its appointed representative is strongly advised.
After a storage period of  years the mechanical seal must be inspected for its “as
new” properties. This applies in particular to the seal faces and secondary sealing
elements. An inspection by Flowserve becomes necessary.
!
If the machine is to be preserved with integrated mechanical seals the preserv-
ing medium must not impair the functions of the mechanical seals by e.g. foul-
ing of the seal faces, hardening, or swelling the secondary seals.
