4.2 Description
V-VC 50, V-VC 75, V-VC 100 and V-VC 150 150 have a micro fi lter on the intake side and an oil and oil mist
separator for the return of the oil to the oil system on the outlet side. The vacuum pump is housed in a
sound cover. A fan between the pump housing and the motor cools the air in the pump housing and cools
the circulating oil.
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 fi tted as standard (Fig. 2/U) prevents condensation of water vapour in the inside of the
pump when low amounts of steam are sucked in when the pump is at operating temperature. A reinforced
gas ballast (optional) can be used if there is a higher amount of water vapour.
The pumps are driven by standard fl anged three-phase motors using a coupling.
4.3 Areas of application
These oil-fl ooded rotary vane vacuum pumps V-VC 50, V-VC 75, V-VC 100 and V-VC 150 are suitable for producing vacuums. The nominal pumping capacity with free suction is 100 50, 70, 100 and 150 m
3
/h at 50 Hz.
Data sheet D 261 shows the dependency of the pumping capacity on the intake pressure.
These types are suitable for the evacuation of closed systems or for a continuous vacuum within the follow-
ing intake pressure ranges: 0.5 to 500 mbar (abs.).
If the machine is operated continuously 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.
For permanent operation of > 100 mbar (abs.) the next larger motor output must be used.
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 motor’s electrical data is given on the data
plate (Fig. 2/N) or on the motor data plate (Fig. 2/
). The motors comply with DIN EN 60034 and
P
1
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). Compare the motor data 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).
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

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.

6.1.1 Checking the rotation direction
The drive shaft direction of rotation is shown by
the rotation direction arrow (Fig. 2/O) on the motor fl ange.
a) Start the motor briefl y (max. two seconds) to
check the direction of rotation. When looking at
the motor fan, it must rotate clockwise.
NOTICE
Incorrect direction of rotation
Operating in the wrong direction of rotation leads
to damage to the machine.
Use a phase sequence indicator to check the direction of rotation (anti-clockwise rotating fi eld).
b) After correcting the direction of rotation if nec-
essary, start the motor again and stop it again
after 2 minutes in order to top missing oil up to
the upper edge of the sight glass (Fig. 2/I). This
topping up at the fi lling point (Fig. 2/ H) must be
repeated until all the oil pipes have been fi lled
completely. The fi lling point must not be open
when the pump is running.
6.2 Decommissioning/ storing
Stop the machine
a) Switch the machine off.
b) If available close the cut off device in the suction
and pressure pipe.

NOTICE
Always change the oil when the machine is at
operating temperature and in an atmospherically
ventilated area.
If it is not completely emptied the amount that can
be refi lled is reduced.
The waste oil must be disposed of in compliance with
the local environmental protection regulations.
If you are going to use another oil type, empty the
oil removing device housing and oil cooler completely.
The oil level must be checked at least once a day,
if necessary top the oil up to the upper edge of the
sight glass (Fig. 7/I) First oil change after 500 hours
of operation. Subsequent oil changes after 5002000 hours of operation. Reduce the change intervals accordingly depending on how contaminated
the discharged medium is.
Only lubricating oils complying with DIN 51506
group VC/VCL or a synthetic oil approved by Elmo
Rietschle must be used. The viscosity of the oil must
comply with ISO VG 100 as per DIN 51519. Elmo Ri-
etschle oil types: MULTI-LUBE 100 (mineral oil) and
SUPER-LUBE 100 (synthetic oil) see also oil recommendation plate (Fig. 7/M)).
If the oil is subject to high temperatures (ambient or
intake temperatures over 30°C, insuffi cient cooling,
60 Hz operation etc.) the oil change interval may be
extended by using the recommended synthetic oil.

7.2.4 Oil removal
Maintenance and repair
open closed
Fig. 8 Air oil remover
WARNING
Heavily contaminated air oil removing devices lead
to increased pump temperatures and in extreme
cases may cause the lubricating oil to ignite spontaneously.
The oil separator elements (V-VC 50/ 75 ➝ 3x, V-VC
100/150 ➝ 4x) can become contaminated by dust
particles after they have been running for some time
(power consumption and pump temperature increase). Replace these components (Fig. 7/L) every
2000 operating hours or when the fi lter resistance is
0.7 bar (see pressure gauge ➝ Accessories, Checking with short term, atmospheric suction) because it
is not possible to clean them.
Reduce the change intervals accordingly depending
on how contaminated the discharged medium is.
Changing: Undo the air oil removers (Fig. 7/L) with a
ring spanner (spanner width 19 mm or 3/4”) rotating
counter clockwise. Insert new air oil removers with
the open lock symbol (see Fig. 8) with the arrow ▼
on the insert and fi x turning clockwise (until it clicks
into place).
