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.

4.3 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 unre­stricted suction is 10 and 15 m3/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 fol­lowing 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 open­ing. 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).

Installation

5.5 Connecting the motor

DANGER

Danger of death if the electrical installation has
not been done professionally.

The electrical installation must only be done by a
qualifi ed electrician observing EN 60204. The ope­rating company has to provide the main switch.

a) The electrical motor data can be found on the

data plate (Fig. 2/N). The motors comply with
DIN EN 60034 and are in protection class IP 55
and insulation class F. The appropriate connec­tion diagram is located in the motor‘s terminal
box (not for the plug connection version). The
motor data must be compared with the data
of the existing mains network (current type,
voltage, network frequency, permitted current
value).

b) Connect the motor via the motor protection

switch (for safety reasons, a motor protection
switch is required and the connecting cable
must be installed via a cable fi tting to provide
strain relief).SFlbWe recommend using motor
protection switches with delayed switch off, de­pending on possible excess current. Temporary
excess current can occur when the machine is
started cold.

NOTICE

Power supply

The conditions at the installation location must match
the information on the motor data plate. Without
derating the following is permissible:

• ± 5% Voltage deviation

• ± 2% Frequency deviation

WARNING

Improper use

May lead to severe or fatal injuries. Therefore be
sure to obey the safety instructions.

CAUTION

Hot surfaces

When the machine is at operating temperature
the surface temperatures on the components (Fig.
2/Q) may go above 70°C.
You must avoid touching the hot surfaces (mar­ked with warning plates).

CAUTION

Noise emission

The highest noise pressure levels measured as
per EN ISO 3744 are given in Section 9.
When spending a long time in the vicinity of the
running machine use ear protectors to avoid per­manent damage to your hearing.

CAUTION

Oil aerosols in the extracted air

In spite of the air oil removing system separating the
oil mist to a large extent, the extracted air contains
a small residue of oil aerosols. Breathing in these
aerosols all the time could damage your health.
Therefore you must ensure that the installation room
is well ventilated.
