1 Description
Sogevac®pumps are designed for pumping of inert gases in the range of
rough vacuum, between atmospheric pressure and ultimate pressure of the
pump.
When removing condensable vapors, periodic opening of the gas ballast
valve is required.
1.1 Principle of operation
The Sogevac®pumps SV40 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. 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 pressures.
The pumps are equipped with a gas ballast valve for pumping condensable
vapors.
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 necessary to mount a separate safety valve on the pump inlet.

Transport and storing
2 Transport and Storing
2.1 Transport and packaging
Sogevac®vacuum pumps pass a rigorous operating test in our factory and
are packaged to avoid transport damages.
Please check packaging on delivery for transport damages.
The outer package bears a shock indicator, turning red at 50 g. Should the
shock indicator have reacted, a transportation damage may have occurred
and the freight forwarder must be advised.
Packing materials should be disposed off according to environmental laws or
re-cycled. 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 cans beside the pump.
2.2 Mounting orientation
See required space on drawings in paragraph 1.2.
Pumps which have been filled with oil must only be moved in the upright
position (horizontally). Otherwise oil may escape. The angle of slope may not
be over 10° max. Avoid any other orientations while moving the pump.
Only use the lifting lugs which are provided on the pump to lift the pump with
the specified lifting devices.
Make sure that these have been installed safety. Use suitable lifting
equipment. Make sure that all safety regulations are observed.
2.3 Storing
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) and
store the pump in a dry place at room temperature.
Storage temperature: - 15°C to + 50°C.
Until the pump is put back in to service again, the pump should be stored
in a dry place, preferably at room temperature (20 °C - 168 °F). Before
taking the pump out of service, it should be properly disconnected from the
vacuum system, purged with dry nitrogen and the oil should be exchanged
too. The gas ballast must be closed and if the pump is to be shelved for
a longer period of time it should be sealed in a plastic bag together with a
desiccant (Silicagel).
If the pump has been shelved for over one year, standard maintenance must
be done and the oil must be exchanged too before the pump is put in to
service once more.
We recommend that you contact the service from Oerlikon Leybold Vacuum.

3 Installation
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.
The standard pump is not suitable for installation in explosion hazard ATEX
areas. Please contact us, if you are planning such an application. Before
installing the pump you must reliably disconnect it from the electrical power
supply and prevent the pump form running up inadvertently.
Observe all safety regulations.
3.1 Setting up
The pump must be set up or mounted horizontally on a flat surface. Special
mounting is not required.
The pump must be levelled within a tolerance of ± 2 degrees.
The following ambient operating environment must be observed:
■Pollution degree CSA 2
■Ambient temperature: 12 °C to 40 °C (54 °F to 104 °F),
■Ambient pressure = Atmospheric pressure.
■Rel. humidity ≤ 95 % without condensation
In order to avoid over-heating of the pump, an undisturbed fresh airflow to
the pump is necessary.
Additional warning note : consider changes in ambient temperatures that
might occur when air conditioning is turned down, such as nights and week-
ends.
Inlet connection
See safety instructions page 3.
■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 open.
■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 vapors, a gas ballast valve must be open
periodically to avoid solvent build up in the oil.
■Additional warning note: additional air flow may be needed during ballast, as
this increases pump temperature.
■The inlet pressure must not be above atm. pressure.
See also indications on the CSA pump nameplate.

The electrical installation may only be conducted by a specialist. Local
regulations have to be followed.
Electrical connection work must only be carried out by a qualified electrician
in accordance with the applicable safety rules, see IEC 60204-1.
The motor must be protected by magnetic thermo breaker type GV2 ME14
adjustable from 6 to 10 A from Schneider Electric or similar.
For an operation at 50 Hz the breaker must be set at 8.5 A. For an operation
at 60 Hz the breaker must be set at 10 A.
Therefore, even if the pump is not operating, live voltage is present in the
motor connection box !
Voltage and frequency mentioned on the pump nameplate must agree with
the supply voltage.
.
Connection to exhaust side
■No valve 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).
The maximum exhaust pressure must neither exceed 1.15 bar absolute (0.15
bar relative), nor fall under atmosphere pressure minus 15 mbar.
3.2 Electrical connections
Ensure that incoming power to the pump is off before wiring the motor or
altering the wiring.

The motor connection box integrates an ON/OFF 24 VDC relay. The pump
operation is commanded with a 24 VDC signal lead through a dedicated
cable.
The final end product must provide a 24 VDC signal (protected by a 3 A fuse) for
the remote control power relay coil. This 24 VDC signal shall be generated by a
power supply complying to IEC 61010-1: 2001 (2nd Edition) double or reinforced
insulation requirements (equivalent standards requirements like IEC60950-1) are
acceptable.
3.3 Oil filling
For SV40 BI, the necessary oil is supplied in cans beside the pump.
To fill in the oil, unscrew the oil fill plug (58) and fill in until the oil level rea-
ches the “MAX” mark beside the oil sight glass. Typically the whole 1 l oil can
is used

Operation
4 Operation
4.1 Operation
To avoid overloading the motor, do not start the pump more than 6 times
within one hour. If more than 6 starts per hour are necessary keep the pump
running and mount a valve which opens and closes into the intake line.
Take note of warning labels on the pump.
Pumping of non-condensable gases
If the pump system contains mainly non condensable gases, the pumps
should be operated without gas ballast.
If the composition of the gases to be pumped is not known and if
condensation in the pump cannot be ruled out, run the pump with gas ballast
valve open in accordance with section below.
Pumping of condensable gases and vapors
With the gas ballast valve open and at operating temperature, the Sogevac®
pumps can pump pure water vapor up to the values indicated in the
Technical Data.
The gas ballast valve is open by a hand lever. The running noise of the pump
is slightly louder if the gas ballast valve is open. Before pumping vapors
ensure that the pump has warmed up for approx. 30 min. with closed intake
line and with open gas ballast valve.
Don’t open the pump to condensable vapors until it has warmed to operating
temperature (approximately); pumping process gas with a cold pump results
in vapors condensing in the oil.
For processes with a high proportion of condensable vapors, the intake line
should be open only slowly after reaching the operating temperature.
One sign of condensation of vapors in the pump is a rise of the oil level
during operation of the pump.
When vapors are pumped, the pump must not be switched off immediately
after completion of the process because the condensate dissolved in the
pump oil may cause changes or corrosion. To prevent this, the pump must
continue to operate with open gas ballast valve and closed intake port until
the oil is free of condensate. We recommend operating the pump in this
mode for at least 30 min. after completion of the process.
Daily ballasting is recommended when continuously pumping larger volumes
of condensable vapors.
In cycle operation, the pump should not be switched off between the cycles
but should continue to run with gas ballast valve open and intake port closed
(if possible via a valve). Power consumption is minimal when the pump is
operating at ultimate pressure.
Once all vapors have been pumped off from a process (e. g. during drying),
the gas ballast valve can be closed in order to improve the ultimate pressure.
Note
Caution

14 GA02329_002_03 - 01/2010 - © Oerlikon Leybold Vacuum
4.2 Working in cycles in / out
We recommend strongly to limit starting of the pump to 5 or 6 per hour.
If the process need it, we recommend utilization of a pneumatic or
electromagnetic valve and to let the pump run continously.
4.3 Switching off / Shutdown
The intake port of the Sogevac®pumps contains an anti-suckback valve
which closes the intake port when the pump is switched off, thus maintaining
the vacuum in the connected apparatus and preventing oil from being
sucked back into the apparatus. The valve’s functioning is not impaired by
gas ballast operation.
If the pump has to be shutdown, drain the oil flush out the pump with
fresh oil and fill in the required amount of clean oil (see § 5.4). Close the
connection ports. Special preservation or flushing oils do not need to be
used.
When the pump has been switched off due to over heating, initiated by the
motor or its temperature detector, the pump must be cooled down to the
ambient temperature, and must only be switched on again manually after
having eliminated the cause.
In order to prevent the pump from running up unexpectedly after a mains
power failure, the pump must be integrated into the control sytem in such a
way that the pump can only be started by a manually operated switch. This
applies equally to emergency cut-off switches.
In case of switching processes in connection with a pump which has warmed
up under operation conditons, the pump must then not be directly switched
on again.

contaminated or is free of substances which could pose a health hazard.
If it is contaminated, specify exactly which substances are involved. You must
use the form we have prepared for this purpose.
A copy of the form has been reproduced at the end of these Operating
Instructions: “Declaration of Contamination for Compressors, Vacuum Pumps
and Components”. Another suitable form is available from
www.oerlikon.com →Oerlikon Leybold Vacuum Systems →Documentation
→Download Documents.
Attach the form to the equipment or enclose it with the equipment.
This statement detailing the type of contamination is required to satisfy legal
requirements and for the protection of our employees.
We must return to the sender any equipment which is not accompanied by a
contamination statement.
The pump must be packaged in such a way that it will not be damaged
during shipping, and so that no harmful substances can escape from the
package.
When disposing of used oil, please observe the relevant environmental
regulations.
5.4 Maintenance Work
Checking the oil
A. Oil level
The oil level shall be checked at least once a day and must be, while the
pump is in operation, close to the MAX marks. Should the oil level be below
the MIN mark switch off the pump, check it (see chapter 4) and add the
required amount of oil.
Oil level may drop when pump is operating due to oil distribution in the
pump.
B. Oil Change
Oil must be changed after the first year of service. Further oil changes must
be done annually. If there is considerable pollution, it could be necessary to
change the oil more frequently.
Oil changing must be done with a switched off and still warm pump. Open
the oil drain plug and let the used oil run out into an appropriate container.
Refasten the oil drain plug when oil runs slowly. Switch ON the pump briefly
(5 sec. max.) and switch OFF immediately. Reopen the oil drain plug and
drain the rest of the oil.
Additional warning note: more frequent oil changes may be necessary if the
ambient temperature is above 30 °C.
Before refastening the oil drain plug, inspect the o-ring and verify that it is
free of particulate and is seated properly. Replace if necessary.
The pump should be "flushed" if there is considerable pollution.

Maintenance
To flush the pump, for clean oil up to the minimum level, let the pump run for
a few minutes and drain the oil. Install a full charge of oil, 1 liter.
C. Replacing the exhaust filters
Oil mist escaping from the exhaust during operation indicates that the filter
is probably clogged. Increased energy intake by the motor could also be
the result of a soiled exhaust filter. Open the exhaust hood, take out the filter
and replace it. Also check the gasket of the exhaut flange and change it if
necessary.
D. Gas ballast valve cleaning
To clean the gas ballast valve, disassemble the fan cover and the fan.
Unscrew the lateral pressure screw, remove the plug and the gas ballast
valve by using an appropriate M10 screw screwed in the valve by pulling on
the screw.
Clean the membrane, the seat and the RILSAN tube.
Reassemble in the reverse sequence.
E. Inlet flange sifter cleaning
To clean the inlet flange sifter, disconnect the inlet flange and clean the sifter
with blast air or an appropriate solvent.
F. Anti-suck back valve checking
The anti-suck back valve should be checked at the same time as the inlet
flange sifter and if dirty, be cleaned with an appropriate solvent.
Also check, if there is no damage on the sealing part of the valve.
G. Fan cover cleaning
Soiling of the fan cover may lead to overheating of the motor and the pump.
Put off the cover and clean it with blast air.
Before starting the pump again, be sure that the cover has been
reassembled.
H. Checking the float valve
When replacing the exhaust filter, check the cleanliness and the proper
operation of the float valve. After having disassembled the exhaust flange
and oil casing, remove screw (pos. 57d), pull on the float valve (pos. 57),
clean the nozzle and check that the float itself oscillates free around its
axle and that the valve is tight. Clean the float chamber of the oil casing.
Reassemble in the reverse sequence.
