Operation
1. Ensure that the sealing chamber
A
is filled application-specifically and vented and sealing
chamber
C
is filled with PTFE grease, see "Lubricating the radial shaft seal", page 30.
2. Screw out the screw plug
2
at the top of the sealing chamber
B
and mount the quench tank
1
.
3. Open the screw plug
2
of the opposing vent hole by a maximum of two rotations.
4. Fill the quench liquid into the quench tank until it is emitted from the vent hole.
5. Tighten the screw plug again.
6. Then fill the quench tank with quench liquid while observing the maximum and minimum filling level,
Variant 3: Filling the sealing chamber B with quench liquid via the circulation line
1. Ensure that the sealing chamber
A
is filled application-specifically and vented and sealing
chamber
C
is filled with PTFE grease, see "Lubricating the radial shaft seal", page 30.
2. Screw out both screw plugs
2
of the sealing chamber
B
.
3. Connect the system-side circulation line for the quench liquid to both holes (input, output).
4. Ensure that the sealing chambers
A
and
C
are filled with PTFE grease, see "Lubricating the radial
CAUTION
When quench liquid is missing damage to seals through hardening of the pumped liquid.
► Check filling level of the quench tank every four weeks and refill quench liquid if necessary.

CAUTION
When quench liquid is missing damage to seals through hardening of the pumped liquid.
► Ensure that the circulation line pumps the quench liquid with sufficient pressure so that the sea-
ling chamber B is filled permanently during operation.
