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.
Handle the seal parts with extreme care to prevent
damage. Be careful not to contaminate precision
finished faces; even fingerprints on the faces can
shorten seal life. If necessary, clean the faces with a
non-oil based solvent and a clean, lint-free tissue.
Wipe lightly in a concentric pattern to avoid
scratching the faces.
Inspect the seal components for wear, scoring,
grooves, and other damage that might cause leak-
age. Clean and polish the shaft sleeve, or replace it
if there are nicks or cuts on either end. If any com-
ponents are worn, replace the complete 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 O-
rings and bellows with water or a very small
amount of oil, and apply a drop of light lubricating
oil on the finished faces. Assemble the seal as fol-
lows, (see Figure 3).

This seal is not designed for operation at
temperatures above 160
_F (71_C). Do not
use at higher operating temperatures.
Inspect the seal plate, shaft sleeve and the impeller
shaft for burrs or sharp corners, and remove any
that exist.
If the shaft sleeve (15) was removed for replace-
ment, heat the replacement sleeve to a uniform
temperature no higher than 250
_F (120_C). Posi-
tion the sleeve on the shaft with the chamfered end
