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).

The pumps are intended for installation. Before putting them
into service it must be established that machinery or equipment
in which they are installed meets the relevant regulations.
WARNING
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 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 is not ex-
ceeded.

Ensure that the pump outlet is not closed or
constricted.
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 front
page for telephone number).
