1 General Instructions
1.1 Safety instructions
In this paragraph, the most important safety and usage instructions for the
SOGEVAC pumps are listed. Ahead of each following paragraph of the manual,
the numbers of the applicable safety instructions will be listed.
1.1.1
SOGEVAC pumps are not designed:
. for pumping of aggressive, corrosive, flammable or explosive gases or gases
mixtures ;
. for pumping of oxygen or other highly reactive gases with a greater
concentration than atmospheric concentration (>20%) ;
. for working in flammable or explosive environment. For all these cases, special
materials must be used. In case of doubt, please contact Oerlikon Leybold
Vacuum.
See also the limits of use indicated in the EC Declaration of Conformity.
1.1.2
Liquid and solid particles must not enter the pump. Install the adequate filters,
separators and/or condensers. In case of doubt consult Oerlikon Leybold
Vacuum.
1.1.3
The intake line of the pump must never be connected to a device with over
atmospheric pressure. Size of the exhaust line so that no pressure higher than
1,15 bar abs. (0,15 bar rel.) or depression of 15 mbar (0,15 bar rel.) can occur
1.1.4
Operating of the pump without oil or operating with incorrect sense of rotation
can destroy the pump.
1.1.5
Never expose part of the body to the vacuum. There is a danger of injury. Never
operate the pump with an open and thus accessible inlet. Vacuum connections
as well as oil filling and oil draining openings must not be opened during
operation of the pump.
1.1.6
When operating pump is hot and some surfaces could reach a temperature
higher than 80°C (176°F). There is a risk of burn by touching.
Switch off the pump and let it cool down before any intervention or take
appropriate precautions.
1.1.7
Depending on the process involved, dangerous substances and oil may escape
from the pump. Take the necessary safety precautions !
1.1.8
Observe the safety regulations !
Never use discarded seals. Always assemble using new seals.
Respect the instructions concerning environment protection when discarding
used oil or exhaust filters !

1.2 Application range
See prescriptions chapters 1.1.1. and 1.1.2.
SOGEVAC pumps are designed for pumping of inert gases in the range of
medium vacuum, between atmospheric pressure and ultimate pressure of the
pump.
Indoor use up to 1000 m altitude and rel. humidity ≤ 95 % without
condenstion
When removing condensable vapours, a gas ballast valve must be installed, or
opened.
1.3. Principle of operation
The SOGEVAC pumps SV28 BI are single-stage oil sealed rotary vane vacuum
pumps. The rotor, having three slots in which the vanes are sliding, is
eccentrically installed in a pump cylinder (stator).
The vanes separate the interior space into 3 chambers. The volume of these
chambers varies with the rotation of the rotor.
The gas sucked into the inlet chamber is compressed and then pushed out at
the exhaust valve.
The oil injected in the inlet chamber guarantees the air-tightness, the
lubrication and cooling of the pump. It is dragged off by the compressed
gases and roughly separated by gravity when entering in the oil sump. A fine
separation is then operated in the exhaust filter. The exhaust filter retains
> 99,9% of the aerosols. An internal transfer pushes the collected oil back
into the vacuum generator, the transfer is operated by a float valve to avoid
atmospheric air coming from the oil casing to the inlet of the pump when no oil
is present in the recovery system.
The oil circulation functions by differential pressure.
Depending on catalog numbers, the pumps are equipped with a gas ballast
valve for pumping condensable vapours.
The anti suckback valve at the inlet flange avoids oil coming back into the
inlet line when the pump is stopped. This is valid for working pressures below
100 mbar and under the condition that the valve is kept clean and in good
condition. The anti suck-back valve is not a safety valve. If oil back flowing is to
be avoided by all means, it is ncessary to mount a separate safety valve on the
pump inlet

These operating instructions are part of the consignment. The connection ports
are blanked off by plastic protective caps or self-adhesives. Take these caps or
self-adhesives away before turning on the pump.
The necessary oil is supplied in a can beside the pump.
1.7 Mounting orientation and storage
1.7.1 Mounting orientation :
See required space on chart in paragraph 1.4. Pumps which have been filled with
operating oil must only be moved in the upright position (horizontally). Other-
wise oil may escape. The angle of slope may not be over 10° max. Avoid any
other orientations while moving the pump.
1.7.2 Storage
Before stocking the pump for a long time put it back in its original condition
(blank off inlet and exhaust ports with the shipping seals, drain the oil sump) and
store the pump in a dry place at room temperature. A storage period excee-
ding one year requires a pump maintenance. Please contact Oerlikon Leybold
Vacuum's customer service.
Storage temp. : - 15°C to + 60°C.
1.8 Lubricants
The SOGEVAC SV28 BI pumps should be run with mineral oils for vacuum pumps
with low viscosity according to ISO category VG32. The Oerlikon Leybold Vacuum
oil GS32 corresponds to these prescriptions.

2 Installation (see chapter 1.1)
It is essential to observe the following instructions step by step to ensure safe
start-up. Start-up may only be conducted by trained specialists.
2.1 Setting-up
The pump must be set up or mounted horizontally on a flat surface. Special
mounting is not required.
The following ambient operating environment must be observed :
. Ambient temperature: 15°C to 40°C (59°F to 104°F),
. Ambient pressure = Atmospheric pressure.
In order to avoid over-heating of the pump, an undisturbed fresh airflow to the
pump is necessary.
GA02331_002_01 - 09/2007 - © Oerlikon Leybold Vacuum

2.2 Inlet connection (see chapter 1.1)
The inlet flange can be connected with a vacuum-tight flexible hose and/or
pipe. The pipes should cause no stresses on the pump’s flanges. If necessary,
compensators must be installed.
Restriction of the pipes must be avoided in order not to decrease the pumping
speed of the pump. The nominal diameter of the pipes has to be at least the
same as the diameter of pump’s inlet flange.
When removing condensable vapours, a gas ballast valve must be installed or
opened.
The inlet pressure must not be above atm. pressure.
2.3 Connection to exhaust side
No isolation or restricting devices should be installed in the exhaust line of the
pump. If an exhaust line is installed, it must at least have the same diameter as
the exhaust flange. It should be installed in a manner so that no condensate can
enter the pump (siphon, slope).
Warning: The maximum exhaust pressure must neither exceed 1.15 bar absolute
(0.15 bar relative), nor fall under atmosphere pressure minus 15 mbar.
2.4 Oil filling (see chapter 1.1.4)
The necessary oil is supplied in a can beside the pump. To fill in the oil, unscrew
the oil fill plug and fill in until the oil level reaches the “MAX” mark beside the oil
sight glass.
2.5. Electrical connection (see chapters 1.1.4 and 1.1.5)
The electrical installation may only be conducted by a specialist. Local
regulations have to be followed.
. Voltage and frequency mentioned on the motor nameplate must correspond
with the supply voltage and frequency.
. The drive motor must be protected against overloads according to local
regulations and IEC 60204-1.
. To check the direction of rotation of pumps, flick pump on. If the direction
of rotation is not identical with the one indicated by the arrow sticking on the
motor hood, then inverse any two of the 3 electrical phases in the terminal box.
Looking at the motor fan cover, the direction of rotation has to be counter-
clockwise.

2.6 Operating advices (See chapters 1.1.1, 1.1.2, 1.1.3 and
1.2)
When removing condensable vapours, a gas ballast valve must be installed or
opened.
The vacuum pump must be run for 30 minutes prior to operation with the
inlet connection closed, in order to reach the operating temperature of about
75°C. Only up from this operating temperature, condensable vapours can be
transported. After use, the pump has to be left running for an additional 30
minutes with the inlet connection closed and open gas ballast, to clear the oil of
condensate.
2.7 Shutdown
The inlet flange of the SOGEVAC pumps contains an anti-suck back valve. It
closes the inlet flange when the pump is voluntarily or accidentally shut down,
thus maintaining the vacuum in the connected system and preventing oil from
being sucked back into the system.
Except the indications in chapter 2.6 (operating advices) there are no particular
precautions for the shutdown of the pump.
If the pump must be stopped for a longer period, see chapter 1.7.
