4.2 Description
The V-VTR model range has a connecting thread on the suction side and an exhaust silencer on the pressure side. The aspirated air is cleaned by an inbuilt fi ne micro fi lter. The carbon dust caused by the scoring
of the blades can be separated by an integral fi lter if necessary. A fan between the compressor housing and
the motor provides intensive air cooling. The compressor housing is located in a sound cover.
The machines are driven by standard fl anged three-phase motors using a coupling.
A vacuum regulating valve (Fig. 2/C) is used to set the vacuum to the required values with an upper limit.
4.3 Areas of application
These dry running rotary vane vacuum pumps V-VTR 100 and V-VTR 140 are suitable for evacuating closed
systems and for a permanent vacuum in the intake pressure range 150 - 1000 mbar (abs.).
The pumping capacity with unrestricted suction is 100 and 140 m
3
/h at 50 Hz. Data sheet D 261 shows the
dependency of the pumping capacity on the intake pressure.
These dry running machines are suitable for conveying air with a relative humidity of 30 - 90%.
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).

data of the existing mains network (current type,
voltage, network frequency, permitted current
value).
b) Connect the motor via plug-connector if fi tted
or 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).
We 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

A bearing (motor side)
The A bearing (motor side) has life long lubrication
and is therefore maintenance free. After 20,000 operating hours or 2½ years (3- shift operation), the A
s
s
bearing must be replaced by a qualifi ed professional
or by our authorised workshops.
B bearing (side facing away from the motor)
The B bearing (on the side facing away from the mo-
a
tor) must be lubricated on the grease nipple (Fig. 4/
L) with 4g of grease after 3,000 operating hours but
no later than after one year. To lubricate the inlet

7.2.2 Blades
Blade check:
V-VTR models have 4 carbon blades that gradually
wear out during operation.
First check after 3,000 operating hours and then
every 1,000 operationg hours or, depending on the
height (Fig. 6/X) earlier.
Remove inlet grating (Fig. 4/G) as well as screws
(Fig. 5/s). To lift the housing lid (Fig. 5/b) from the
housing two screws (Fig. 5/s) must be screwed into
the two tapped holes (Fig. 4/a) on the housing lid
evenly. Remove the blades (Fig. 5/d) to be checked.
All blades on the machine must have a minimum
height (Fig. 6/X) of more than 26 mm (V-VTR 100)
and 32 mm (V-VTR 140) and a minimum thickness
(Fig. 6/W) of more than 2.5 mm.
The blades must only be changed as a set.

Maintenance and repair
Changing blades:
If the minimum height or the minimum thickness has
already been reached or if the blades have fallen
below these levels the whole blade set must be
changed.

G
Blow out the housing and rotor slot. Insert the
1
blades into the rotor slot. BWhen doing this you
must ensure that the blades with the sloping side
sd
(Fig. 6/Y) point outwards and the direction of rotation of these sloping sides (Fig. 6/O1) matches that
of the drilled holes for the housing (Fig. 6/Z).
Before putting the housing cover (Fig. 5/ b) back
onto the shaft end the excess grease in the grease
store (Fig. 5/c) of the B bearing must be completely
removed from the bearing cage. Also grease residue
should be wiped off the end of the shaft and where
the shaft passes through the housing lid. Otherwise
this grease would get into the compressor housing
and would mix with the blade wear debris to form
a paste-like coating that could cause the blades to
jam in the rotor slots.
When screwing the housing lid on the grease-free
screws should be tightened alternately and evenly
so that the lid does not get jammed on the locating
pins. As soon as the lid is almost resting on the front
of the housing, it is advisable to turn the fan to and
fro (using a screw driver or similar) while you fi nish
Y
screwing in the screws. This will prevent the corners
of the blades getting jammed and breaking away.
