When disassembling seal, inspect for conditions which may have caused the
need for the seal to be removed from service. If seal was removed due to
premature failure, determine what conditions caused that failure and correct any
problems prior to returning the repaired seal to service. For assistance with seal
failure analysis, please contact your Flowserve representative.

Seal Parts that are always replaced
3.1 There are certain critical areas of each part where special attention should be
paid to the condition. If any of the areas listed in 3.2, 3.3 or 3.4 show signs of
wear, corrosion, or other defects that cannot be removed without affecting
the dimensional size of the surfaces by more than 0.001 to 0.002", then the
respective part should be replaced. If grit blasting is performed, it may be
necessary to polish the O-ring surfaces to achieve the required surface finish
(see 3.2A and 3.3A for the required surface finish). If any parts require
machining to correct damage, please contact your Flowserve representative
for dimensional requirements, or for any other questions regarding repair.
A Mating ring O-ring surface - Inspect for wear,
fretting, nicks, scratches, or corrosion.
Required surface finish : 63 RMS
B Gasket surface - Remove the old gasket
and clean the gasket surface. Inspect for
nicks, scratches, or corrosion.
C Pipe taps and other threaded holes -
Inspect for damaged threads or corrosion.
Taps must be clean and free of debris and
corrosion. Re-tap as necessary.
D Bushing - Inspect for wear, breakage, or
loosened bond with gland. Replace using
Loctite
®1 7471 Primer T and Loctite RC TM /640
or equivalent to adhere the bushing if any of
these conditions exist. A ten minute cure at 400
°
F
(204
°
C) is required to achieve full bond strength.
If worn or corroded, contact your Flowserve representative.
E Gland drive ring 1B - Inspect for wear or corrosion.
