4.3.4 Pressure in the barrier system
The pressure in the barrier system should be approx. 2 bar higher than the operating
pressure in the pump chamber. The pressure is generated/reduced by filling / releas-
ing compressed air or inert gas (e.g. nitrogen, argon) at the pressure valve.
Note
Both the pressure (

pressure gauge) and the filling
level (

inspection glass) of the barrier should be
checked daily.
Danger
Maintenance and repair work on the barrier system may
only be carried out by personnel specially trained for
this purpose.
Depressurise the barrier system prior to maintenance
and repair work!
Replace the hose lines at regular intervals as a preven-
tive maintenance measure, even if no damages can be
detected!
(Observe the manufacturers' indications!)
Before starting the system after maintenance or repair
work
•
check that unscrewed screw connections sit secure
•
make sure that removed reservoir covers, sieves or
filters have been installed again
Following maintenance and repair work and prior to re-
commencing production, ensure that
•
all of the materials, tools and other equipment re-
quired for implementing maintenance or repair work
are removed from the machine's work area,
•
all liquid leaks are disposed of, and
•
all of the system's safety equipment is functional!
