4.0 Product Seal Fitting and Removal
General Procedures for Installing Seals.
Mechanical seals are precision-engineered assemblies incorporating finely lapped
seal faces and seats. They must therefore be handled with care and will not give
optimum performance unless installed carefully and according to instructions
Where mechanical seals are to be reused ensure that seal components are kept in
their appropriate sets. Do not mix old and new seal faces on the same seal .
Remove any sharp corners and burs that may damage and elastomers such as o-
rings or lip seals.
Ensure that all seal component fitting bores and housings are toughly cleaned before
instillation.
The seal faces are undamaged and the o-rings are not cut, swollen, or cracked.
Lip seals and o-rings within the seal assemblies should be lightly lubricated with an
elastomers compatible, food grade lubricant. Ensure there is not an excessive
amount of lubricant especially around the seal face area.
Ensure seals seats are mounted squarely.
Ensure when installing seals with brittle faces such as silicon carbide that extra care
is taken.
Do not use any excessive force to install a mechanical seal. If it is difficult to position
and assemble the seal then something is wrong.
If you drop or damage a seal, Do not install it before an inspection has been carried
out.
Do not run any seal options dry. WARNING
