Mechanical seal
Instructions for mounting a mechanical seal
First read the following instructions regarding the mounting of a mechanical seal. Follow
these instructions closely when mounting a mechanical seal.
• Leave the assembly of a mechanical seal with PTFE (Teflon) covered O-
rings to a specialist. These rings are easily damaged during assembly.
• A mechanical seal is a fragile precision instrument. Leave the seal in its original
packing until you are ready to fit it!
• Clean all receiving parts properly. Make sure your hands and working environment are
clean!
• Never touch the sliding surfaces with ones fingers!
• Take care not to damage the seal during assembly. Never put the rings down on their
sliding surfaces!
Special tools: Mounting the mechanical seal unit is easier when you use a special
tapered mounting bush. That way, the sharp shaft edges are covered so that the risk of
damaging the seal during assembly is reduced. See figure 10.
