Product overview and functioning
4.5 Fields of application
The screw vacuum pumps are suitable for the evacuation of closed systems or for a continuous vacuum
within the following inlet pressure ranges:

They are also particularly suited for delivering of extremely damp gases. Water vapour compatibility is very
high.
The maximum pumping capacity with unrestricted suction is
300 m
3
/h at 50 Hz
. The data sheets
D 834
and
D 834-UK
show the dependency of the pumping capacity on the inlet pressure.
If the unit is switched on more frequently (at regular intervals of approx. 10 times per hour) or at
higher ambient temperatures and inlet temperatures, excess temperature limit of the motor wind-
ing and the bearings may be exceeded.
Contact the manufacturer regarding such operating conditions.
If it is installed in the open air the unit must be protected from environmental influences (e.g. by a
protective roof).
