Set up and operation
4.3 Areas of application
The screw vacuum pumps are suitable for the evacuation of closed systems or for a continuous vacuum
within the following intake pressure ranges: 0.1 to 1000 mbar (abs.).
They are also particularly suitable for feeding in extremely damp gases. The water vapour compatibility is
very high.
The maximum pumping capacity with free suction is 320 m 3 /h at 50 Hz. Data sheet D 832 / 42 shows the
dependency of the pumping capacity on the intake pressure.
If the unit is switched on more frequently (at regular
intervals of > 10 times an hour) or at higher ambient
temperatures and intake temperatures, the excess
temperature limit of the motor winding and the bear-
ings may be exceeded.Please contact the manufac-
turer should the unit be used under such conditions.
If it is installed in the open air the unit must be pro-
tected from environmental infl uences, (e.g. by a pro-
tective roof).
ACHTUNG
The srew vacuum pump S-VSI 300 (42) with
5.5 kW motor may only be operated in continuous
operation S1.
When evacuating closed systems the volume to
be evacuated must be max. 80 l.
