Seal Installation
(Figures 11 - pg. 23, 14 below, 15 - pg. 31 and 16 - pg. 31)
Most cleaning solvents are toxic and flammable. Use them only in a
well-ventilated area free from excessive heat, sparks, and flame.
Read and follow all precautions printed on solvent containers.
WARNING!
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.
This seal is not designed for operation at temperatures above 71º C.
Do not use at higher operating temperatures.
CAUTION!
A new seal assembly should be installed
any time
the old seal is removed
from the pump. Wear patters on the finished faces cannot be realigned
during reassembly. Reusing an old seal could result in premature failure.
CAUTION!
