Removing Cartridge Mechanical Seals
Before continuing with
cartridge seal replacement:
Important!
Once you’ve
removed the lobes, you must
evaluate the condition of the lobe
core that will contact the Block
Ring.
Lobe condition is critical
to prevent premature seal failure
(
Fig. 10 & 11 ).
Lobes provided before the
development of the Block Ring
seal may have partial coating on
the inner core which mates with
the seal. These lobes may show
small bits or pieces of the coating
in a jagged appearance around
the surface which is not
acceptable when using Block
Ring seals.
New lobes have a smooth, clean,
machined appearance and show
no jagged bits of coating. If
lobes are being reused with the
Block Ring seal, attention must
be given to the condition of the
lobe core, assuring that it has not
been damaged.
Unacceptable: Jagged
pieces of coating on inner
core can lead to seal
failure (
Fig. 12 ).
Surface is free
of gouges or
elastomer
fragments.
Surface has
even elastomer
coating with no
gouges.
