Maintenance / Inspection
For SKS with sealing pressure:
•
Check the pressure. The rinsing fluid must always be under pressure if the pump is in
operation, including starting and switching off.
•
Check the temperature of the rinsing fluid continuously
•
With closed sealing systems: Check the condition of the rinsing fluid. If it has become
dirty with leakage fluid, replace it.
Perform the following checks for SKS (catchment chamber system) without sealing
pressure:
•
Check the level in the reserve container
•
Check the temperature of the sealing fluid
•
Inspect the sealing liquid to determine its condition
If you notice that the fluid level has risen above the "Max." mark or if the sealing fluid is
significantly contaminated by leakage fluid, the liquid must be replaced. In this case check
the GLRD (mechanical seal) as well and replace it if necessary.
In normal operation the oil should be replaced at least every 6 months, for emulsion at least
every 3 months. In difficult conditions shorten these times as needed.
In the Ex area:
If the mechanical seal is removed during the system overhaul, it must be replaced by a new
one.
Caution!
For explosion protection areas in accordance with Directive 2014/34/EU, an
additional Operator's Manual must be observed.
•
Check the level, temperature and condition of the liquid in the catchment
chamber continuously!
•
Check the mechanical seal for proper function at regular intervals. A GLRD
must never run dry!
