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
.
During the running-in phase of the M.S. an increased leakage may occur.
If the leakage amount does not decrease 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 the M.S. at outboard side has to be drained and disposed of properly.
IMPORTANT!
Components which may have contact with the leakage have to be
corrosion-resistant or have to be adequately protected.
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 Directive 91/155/EEC) and the
accident prevention regulations
have be observed.
