6.1 Safety instructions for operation
CAUTION
Air intake via the seal faces
Dry running of the seal and consequential seal failure!
▷
For single seals the pressure in the seal chamber of the pump must always be
higher than the ambient pressure.
CAUTION
Unsuitable fluid to be sealed off
Damage to the machinery!
▷
Take appropriate measures to ensure that the fluid to be sealed off at the
mechanical seal is in liquid condition no matter what the operating status of
the pump. This applies in particular when starting up and stopping the pump.
▷
If the fluid to be sealed off forms deposits while the machinery cools down or
during standstill of the machinery, the seal chamber must be flushed through
with a clean liquid. The quantity and type of flushing liquid has to be defined
by the operator for the specific material combination of the mechanical seal.
CAUTION
Excessive rise in temperature
Damage to the mechanical seal!
Dry running or damage to the elastomers, incrustations at the seal faces, etc.
▷
Shut down the pump for safety reasons.
NOTE
If the operating limits indicated are observed and the instructions given in this
manual are complied with, the mechanical seal can be expected to give trouble-free
operation. If the values during operation are not within the specified limits, the
mechanical seal must be removed from the system and sent to KSB for inspection.
6.2 Emissions
▪
For physical and technical reasons a mechanical seal cannot be leak-free.
▪
Leakage can be either in liquid or gaseous form. Its aggressiveness corresponds to
that of the fluid to be sealed off.
▪
The quantity of leakage is influenced by several factors:
–
Seal selection
–
Manufacturing tolerances
–
Operating statuses
–
Smooth running of the pump
▪
In the running-in phase of the mechanical seal higher leakage can occur.
NOTE
If a reduction in leakage cannot be observed or if other failures occur, the
mechanical seal must be stopped for safety reasons, removed from the system and
sent to KSB for inspection.
