Operation Diaphragm pump N96_AC
22 Translation of Original Operating and Installation Instruction, english, KNF 329772-329775 06/22
à
The pumps are built-in devices. Before they are commissioned, it must
be ensured that the machines or systems into which the pumps are in-
stalled comply with the relevant provisions.
WARNING
Risk of pump head bursting due to excessive
pressure increase
à
Do not exceed the maximum permissible op-
erating pressure (see
3 Technical data ).
à
Monitor the pressure during operation.
à
If the pressure exceeds the maximum permis-
sible operating pressure of the pump: immedi-
ately switch off the pump and remedy the fault
(see Chapter
9 Troubleshooting ).
à
Only throttle or regulate the air or gas quantity
on the suction line to prevent the maximum
permissible operating pressure from being ex-
ceeded.
à
If the air quantity or gas quantity on the pres-
sure line is throttled or regulated, make sure
that the maximum permissible operating pres-
sure at the pump is not exceeded.
à
Ensure that the pump outlet is not closed or
restricted.
WARNING
Risk of dangerous gas mixtures during pump op-
eration if diaphragm breaks
If the diaphragm should break, the medium will
mix with the air in the compressor housing or in
the surroundings.
à
Stop pump immediately.
à
Replace the diaphragm prior to further opera-
tion (see Chapter
8 Servicing ).
Operation with open suction-side gas connection can result in con-
taminants and objects being drawn in.
Pump stoppage
à
When the pump is at a standstill, establish normal atmospheric pres-
sure in the lines.
Vapors as medium The service life of the diaphragm can be extended, if no condensate forms
in the pump. Therefore:
à
Perform any work with saturated or near-saturated vapors only with a
warm pump.
à
KNF recommends: When pumping corrosive media, flush the pump
before switching off (see Chapter
8.2.1 Flushing the pump ) to extend
the service life of the diaphragm.
7.2 Information on switching the pump on and off
Switching on the pump
à
Ensure that normal atmospheric pressure is present in the lines when
switching on.
