Emissions
A mechanical seal is a dynamic seal that cannot be free of leakage due to physical
and technical reasons. Seal design, manufacture tolerances, operating conditions,
running quality of the machine, etc. mainly define the leakage value. In fact,
compared to other sealing systems there is few leakage.
WARNING! If the medium to be sealed and/or the supply liquid is subject to the
Hazardous Substances Regulation (GefStoffV), the instructions for handling
dangerous substances (safety data sheets to EU Directive 91/155/EEC) and the
accident prevention regulations have be observed.
A possibly increased leakage during start-up will decrease to a normal quantity after
the running-in period of the sliding faces.
If this is not the case or if there are other malfunctions the mechanical seal has to be
shut down, removed and checked for reasons of safety.
The leakage can be liquid or gaseous. Its aggressiveness corresponds to that of the
medium to be sealed.
Leakage of mechanical seal at outboard side has to be drained and disposed
properly.
IMPORTANT! Components which may get in contact with the leakage have to be
corrosion-resistant or have to be adequately protected.
