Operation
Diaphragm Pump UN035_I EX
16
7. Operation
Only operate the pump under the operating parameters and
conditions described in chapter 4, Technical data.
Make sure the pumps are used properly (see section 2.1).
Make sure the pumps are not used improperly (see section
2.2).
Observe the safety precautions (see chapter 3).
WARNING
Hazard of the pump head bursting due to excessive
pressure increase
Do not exceed max. permissible operating
pressure (see section 4).
Monitor pressure during operation.
If the pressure exceeds the maximum permissi-
ble operating pressure, immediately shut down
pump and eliminate fault (see chapter 9. Trou-
bleshooting).
Only throttle or regulate the air or gas quantity in
the suction line to prevent the maximum permis-
sible operating pressure from being exceeded.
If the air or gas quantity in the pressure line is
throttled or regulated, make sure that the maxi-
mum permissible operating pressure of the
pump is not exceeded.
Excessive pressure (with all of the related hazards) can be
prevented by placing a bypass line with a pressure-relief valve
between the pressure and suctions sides of the pump. For
further information, contact our technical adviser.
With the pump at a standstill, open pressure and suction lines
to normal atmospheric pressure.
For pumps with thermo switch (special design):
WARNING
Automatic starting can cause personal injury and
pump damage
When the operation of the pump is interrupted by the
thermal switch, the pump will restart automatically
after cooling down.
Take all necessary care to prevent this leading
to a dangerous situation.
