Mechanical Seals - General Note
Mechanical seals are precision products and therefore require careful handling and storage to
ensure reliable operation. If the mechanical seals are stored for an extended period of time before
installation or commissioning, the storage conditions may adversely affect the performance of the
seal once it is put into operation. For this reason the user must ensure the storage conditions will
meet the recommendations stated below.
This guideline applies to Flowserve mechanical seals for centrifugal pumps, mixers, and reactors.
Flowserve mechanical seals from the Gaspac product line should use Gaspac Guideline No. 39.
Flowserve will not accept any warranty claims for failures as a result of inadequate storage.
2 Storage of Mechanical Seals in Their Original Packaging
Flowserve mechanical seals are shipped in packaging which is intended to protect the seal from
damage due to shipping and handling. This packaging is also suitable for long term storage. If the
packaging is opened and the seal removed for inspection, the seal should be repackaged and resealed
in its original packaging material and container.
While the packaging is suitable to protect the seal from damage due to normal handling, it is not
designed to protect the seal from handling abuse or poor storage conditions. The seal must also be
stored in an environment which will prevent damage to the seal.
Environmental guidelines for mechanical seals:
• Temperature range 4°C to 37°C (40°F to 100°F)
• Low humidity, less than 65% RH
• Atmosphere free from rain, dust, steam, chemicals, oils, radiation and ozone
• Storage surface free from impact and vibrations
Any loose gaskets should remain in their original packaging during storage.
If the seals will be stored in an outside location and exposed to more extreme environmental
conditions or humidity/moisture, special packaging and seal preparation will be required.
3 Storage of Mechanical Seals Installed in Equipment which is Not Commissioned
Some centrifugal pumps will be stored for months or years prior to installation and final commis-
sioning. The purchaser needs to consider the long-term storage requirements of the pump, bearings,
and motors and resolve conflicts with storage of the mechanical seals and seal support system. The
storage requirements of the pump may not be compatible with seal requirements and the seals may
need to be stored separately from the pump. In this case, the mechanical seals should be stored in
accordance with Storage of Mechanical Seals in Their Original Packaging.
