7. Operation
Only operate the pumps under the operating parameters and
conditions described in Chapter 4, Technical data.
Make sure the pumps are used properly (see Chapter 2.1).
Make sure the pumps are not used improperly (see Chapter 2.2).
Observe the safety precautions (see Chapter 3).
WARNUNG
Hazard of the pump head bursting due to excessive
pressure increase
➔
Do not exceed max. permissible operating
pressure (see Chapter 4, Technical data).
➔
Monitor pressure during operation.
➔
If the pressure exceeds the maximum permissi-
ble operating pressure, immediately switch off
pump and eliminate fault (see Chapter 8. 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 is not ex-
ceeded.
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 (see last page
for telephone number).
➔
With the pump at a standstill, open pressure vacuum and
suction lines to normal atmospheric pressure.
The pump may not start up against pressure or vacuum during
switch-on. This also applies in operation following a brief power
failure.
➔
Make sure that normal atmospheric pressure is present in the
lines during switch-on.
➔
Regulary inspect the pump for external damage or leaks.
Piston seal and valve plates are the only parts subject to wear.
Wear is usually indicated by a drastic reduction in the pneu-
matic performance. When replacing parts proceed as de-
scribed in Chapter 8.
➔
Change the filter (accessories) if it is dirty.
