4.2 Description
V-VGD has a fi ne micro fi lter on the suction side and on the outlet side an oil and oil mist separator to return
the oil to the oil circulation system.
The motor fan cools the motor and pump housing. The motor and the pump have a common shaft.
An integral non-return valve prevents the evacuated system from being ventilated after the pump has stopped.
If the machine has been idle for more than two minutes the connected pipe should be ventilated to atmospheric
pressure.
A gas ballast valve ((Fig. 2/U)
➝Accessory) prevents water vapour condensation getting inside the pump when
low amounts of steam are sucked in when the pump is at operating temperature.

Areas of application
These oil-fl ooded rotary vane vacuum pumps V-VGD 10 and V-VGD 15 are suitable for creating vacuum.
The suction power with unrestricted suction is 10 and 15 m
3
/h at 50 Hz. The pumping capacity with unre-
stricted suction is 10 and 15 m
3
/h at 50 Hz. Data sheet D 230.
The max. fi nal vacuum (fi ne vacuum 2 mbars (abs.) or gross vacuum 10 mbars (abs.) can be specifi ed by the
operator (see adjustment bolt (Fig. 2/X)).
These types are suitable for the evacuation of closed systems or for a continuous vacuum within the fol-
lowing intake pressure ranges: Fine vacuum
➝ 2 - 200 mbars (abs.) • Gross vacuum➝ 10 - 600 mbars
(abs.).
If the unit is operated constantly outside these ranges there is the risk of oil leaking through the outlet open-
ing. When evacuating closed systems the volume to be evacuated must be no more than 2% of the nominal
pumping capacity of the vacuum pump.
If the unit is switched on more frequently (at regular intervals of about 10 times an hour) or at
higher ambient temperatures and intake temperatures, the excess temperature limit of the motor
winding and the bearings may be exceeded.Please contact the manufacturer should the unit be
used under such conditions.
If it is installed in the open air the unit must be protected from environmental infl uences, (e.g. by a
protective roof).
