Installation, Operating and Maintenance Instruction
3.3.2 General informations
The reuse of mech. seals that have already
been used for a longer time can lead to leaking
at the seal faces after reinstallation. Therefore
the replacement of the mech. seal with a new
one is recommended. The removed mechanical
seal can be reconditioned by the manufacturer
and serve as a replacement mech. seal.
3.3.3 Informations for the mounting
Pay
attention
Especially the seal faces must be clean, dry and
undamaged. Don't apply lubrication on the seal
faces of the mech. seal.
If a lubricant is provided with the replacement
mech. seal, you should use this.
Use mineral grease or oil only if you are
completely sure that the elastomers of the
mech. seal are oil resistant. Use no silicone.
Use only lubricants with which you are certain
that no dangerous reaction can occur between
the lubricant and the pumped medium.
Have all required parts prepared so that
assembly can be completed quickly. The
lubricants are only effective for a short time.
After that, the axial mobility and thus the
automatic adjustment of the elastomers is lost.
Never push elastomers over sharp edges. If
necessary, use mounting devices.
During installation, push the mech. seals with a
bellows in such a way that the bellows is
compressed and not stretched (danger of
tearing apart!).
3.4 Bearings
The ball bearings of the pump are greased for life and
are thus maintenance-free.
3.4.1 Used bearings
The exact designation of your pump is shown in the
data sheet and / or order confirmation.
