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.
Replacement seals are shipped with a
spring centering washer. The washer sup­
plied with a new seal will not work for this
application. Discard the spring centering
washer supplied with the seal and use the
washer supplied with the pump (item 5,
Figure 2) or replace it with a new one.
To ease installation of the seal, lubricate the O‐
rings, sleeve 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).
