6.8 Examination of parts
6.8.1 Cleaning/inspection
All parts should now be thoroughly cleaned and
inspected. New bearings, O-rings, gaskets, and lip
seals must be used. Any parts that show wear or
corrosion should be replaced with new genuine
Flowserve parts.
It is important that only non-flammable,
non-contaminated cleaning fluids are used. These
fluids must comply with plant safety and environmental
guidelines.
a)
Inspect impeller (2200) for excessive wear and
etching due to corrosion. Large nicks and deep
pits will unbalance the impeller and cause
vibration and wear in other parts of the pump.
Be sure the o-ring (4610) sealing surface and
impeller threads are clean.
b) Check pump shaft (2100) for straightness.
c) Inspect the surface of the shaft in the bearing
(3020.1-.2) areas to make sure it is smooth. It
must be free of grooves, scratches, corrosion or
wear.
d) Check ends of shaft for burrs. Make sure that
shaft threads are clean.
e) Inspect the casing (1100) thoroughly, removing
all burrs and foreign matter. Check hydraulic
passages for cleanliness.
f) Check all other parts for burrs, wear, damage or
corrosion.
g) Use a dial indicator to check the straightness of
the shaft extension of the driver and check
indicator readings against the values given in
Figure 6-5. Should any of these limits be
exceeded, check with the driver manufacturer
for recommended repair or replacement parts.
