MAINTENANCE & REPAIR
PAGE E - 11
A new seal assembly should be installed
any time
the old seal is removed from the
pump. Wear patterns on the finished faces
cannot be realigned during reassembly.
Reusing an old seal could result in prema
ture failure.
The seal is not normally reused because wear pat
terns on the finished faces cannot be realigned
during reassembly. This could result in premature
failure. If necessary to reuse an old seal in an emer
gency,
carefully
wash all metallic parts in fresh
cleaning solvent and allow to dry thoroughly.
Inspect the seal components for wear, scoring,
grooves, and other damage that might cause leak
age. If any components are worn, replace the com
plete seal;
never mix old and new seal parts
.
If a replacement seal is being used, remove it from
the container and inspect the precision finished
faces to ensure that they are free of any foreign
matter.
To ease installation of the seal, lubricate the shaft
sleeve, shaft sleeve O‐ring and the external station
ary seat O‐ring with a very
small
amount of light lu
bricating oil. See Figure 5 for seal part identifica
tion.
