Seal Installation
(Figures 4, 8, 9 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 shaft
sleeve O‐ring (14) and the external stationary seat
O‐ring with a very small amount of light lubricating
oil. See Figure 8 for seal part identification.
