Bringing the stuffing box into operation
after re-packing
Tighten the stuffing box only slightly before
bringing it into operation. When the pump
starts, a leak rate of 50 to 200 drops per
minute is permitted.
During the running-in process of approximately
30 minutes, tighten the stuffing box gland (203)
incrementally via the hexagon nuts (202) to set
a minimum leak of 2 to 20 drops per minute.
Caution!
The temperature of the stuffing box
may not increase abnormally during
this time. Approximately 20 to 60 °C
above the temperature of the
pumped liquid is permissible. If
temperature increases suddenly,
immediately loosen the stuffing box
gland and repeat the run-in
process. The leak can be directed
through the threaded hole located
in the bearing bracket’s drip pan.
Eliminate any possibility of injury
and environmental damage caused
by leaks of hazardous materials!
9.1.4.2
Mechanical seal
Unbalanced mechanical seals are used in all
material pairings and versions. The mechanical
seal is maintenance free.
In the event of strong wear-induced leaks, the
mechanical seal must be replaced (
section
10.1 page 26).
Caution!
Since dry-running of a mechanical
seal must be avoided, the pump
may be switched on only when
filled and with any additional
equipment switched on (
section
7.1.2 page 18)!
