Seal Reassembly and Installation
(Figures 6 and 10)
Most cleaning solvents are toxic and
flammable. Use them only in a well ven
tilated area free from excessive heat,
sparks, and flame. Read and follow all
precautions printed on solvent contain
ers.
Clean the seal cavity and shaft with a cloth soaked
in fresh cleaning solvent. Inspect the stationary
seat bore in the seal plate for dirt, nicks and burrs,
and remove any that exist. The stationary seat bore
must be completely clean before installing the
seal.
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.
To ease installation of the seal, lubricate the sta
tionary element O‐ring with a very small amount of
light lubricating oil. See Figure 10 for seal part iden
tification.
