Flowserve Mechanical Seal Storage
1 Storage of 3 to 24 Months
There are no known storage problems with complete
Flowserve mechanical seal
assemblies or components
for up to 2 years.
For a complete Flowserve mechanical seal:
1.1 Install the Flowserve mechanical seal in accor-
dance with the installation instructions. Use the
lubricant provided on all O-rings and gaskets,
except PSS drive pads and O-rings in CRO seal
assemblies.
Follow plant safety regulations:
2 Storage Periods Longer than 24 Months
For storage periods longer than 2 years, environmental
conditions may influence the flatness of rotating and
stationary seal faces and cause deterioration of some
O-ring and gasket materials.
For complete Flowserve mechanical seal
assemblies
follow steps 1- 5.
Follow steps 3 - 4 for components.
2.1 Install the Flowserve mechanical seal in accor
dance with the installation instructions. Use the
lubricant provided on all secondary seals, except
PSS drive pads and O-rings in CRO seal
assem-
blies.

1.2 Complete equipment tests. Drain all product and
flush fluid from the equipment and seal chamber.
Dry equipment and seal chamber with com-
pressed air.
1.3 Cover all equipment openings including pump
suction, discharge connections, flush taps, etc.
1.4 Plug all openings in the seal chamber and gland.
1.5 Mask or cover the clearance between the seal
gland and the shaft to prevent dirt and debris from
entering the seal cavity.
1.6 Turn the shaft one to two revolutions by hand
every three months.
Follow plant safety regulations:
lock out motor and valves
wear designated personal safety equipment
relieve any pressure in the system

ial regulations
2.2 Complete equipment tests. Drain all product and
flush fluid from the equipment and seal chamber.
Remove, disassemble, and thoroughly clean and
decontaminate the Flowserve mechanical seal.
Dry all parts, package, and store as individual
components in a cool, clean environment.
2.3 The resistance of elastomeric secondary seal
materials such as O-rings , V-rings, and gaskets,
to deterioration during normal storage conditions
varies with the type of elastomer. SAE ARP5316
lists the maximum recommended storage life for
elastomeric seals. The specification also lists
recommended storage practices. The maximum
storage life of the elastomers listed in Table 1 and
the following storage conditions are taken from
this specification.

Maximum life can be achieved by using the following
storage conditions:
Ambient temperature not exceeding 100° F (38° C)
Exclusion of air and oxygen
Exclusion of contamination and radiation
Exclusion of light, particularly sunlight
Exclusion of ozone generating electrical devices
Generally, storage in polyethylene bags more than
0.075 mm thick and ultraviolet (UV) resistant or
polyethylene lined kraft paper bags ensures optimum
storage life.
Before reinstalling the Flowserve mechanical seal,
inspect all O-rings, V-rings, gaskets, etc., for deteriora-
tion, cracks, or unusual hardness.
2.4 The wear faces of seal rings and inserts should
be tested for flatness using a helium lamp and an
optical flat, prior to reinstallation. In general,
sealing faces should be flat to within 2 light
bands. Contact Flowserve for exact require-
ments if necessary.
2.5. Reassemble and install the Flowserve mechani-
cal seal in accordance with installation instruc-
tions.
