Product overview and functioning
4.5 Fields of application
The claw vacuum pumps are suitable for the evacuation of closed systems or for a continuous vacuum with-
in the following inlet pressure ranges:
400 - 1000 mbar (abs.)
The maximum suction capacity with unrestricted suction is
62 m
3
/h
or
120 m
3
/h
at
50 Hz
.
Data sheet
D 882
shows the dependency of the pumping capacity on the intake pressure.
XD model: The vacuum pump is equipped with a corrosion-protective coating and is suitable for conveying
water-damp gases (water vapour).
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).
4.6 Accessories
The following accessories are options and on request available from Gardner Denver.
4.6.1 Intake filter
The intake filter serves for the protection of the machine from dust and other solids in the process gas.
The intake filter is available with a paper filter or a polyester filter.
4.6.2 Vacuum relief valve
The vacuum relief valve limits the final pressure of the pump. The vacuum relief valve is set at the factory for
the lowest permissible final pressure (see data plate of the pump).
