4.3 Product Seal Fitting and Removal.
4.3.1 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 burrs that may damage any elastomers
such as o-rings or lip seals.
- Ensure that all seal component fitting bores and housings are thoroughly
cleaned before installation.
- The seal faces and seats must be handled with care and cleaned
thoroughly before installation.
- Ensure that seal faces are undamaged and the o-rings are not cut,
swollen, or cracked.
- Lipseals and o-rings within the seal assemblies should be lightly lubricated
with an elastomer compatible, food grade lubricant. Ensure there is not an
excessive amount of lubricant especially around the seal face area.
Lubrication points are available options, for more information contact
JPUK or your JPUK distributor.
- When fitting PTFE encapsulated o-rings it is important to immerse them in
hot water for several minutes to soften them.
- Ensure seal 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.
