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 pumping condensable vapours, a gas ballast valve must be installed.
1.1 Principle of operation
The SOGEVAC® pumps SV10-16 B are single stage oil sealed rotary vane vacu-
um pumps.
The rotor, having three slots in which the vanes are sliding, is eccentrically in-
stalled 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 oper-
ated in the exhaust filter. The proportion of oil in the exhaust gas is thus reduced
below the visibility threshold (over 99% entrapment rate). The collected oil is flow-
ing back to the generator through an internal transfer. A non-return valve is in-
cluded in the oil return screw system to avoid an oil flow from the generator to the
oil casing when the pump works at inlet pressures greater than 150mbar. There-
fore, continuous operation above 150mbar is not recommended and can lead to
oil spilling from the exhaust.
Specific P/N for high inlet pressure duty are available. Please contact us.
Depending on catalog numbers, the pumps are equipped with a permanent gas
ballast for pumping condensable vapours.
The anti suck back valve at the inlet flange avoids oil coming back into the inlet
line when the pump is stopped.
Nevertheless, this is not a safety valve and correct operation is granted only if the
anti suck back valve is clean and in good condition.

2 Transport and storing
2.1 Transport and packing
SOGEVAC® vacuum pumps pass a rigorous operating test in our factory and are
packed to avoid transport damage.
Please check packing on delivery for transport damage.
Packing materials should be disposed off according to environmental laws or re-
used.
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 LVO120 oil is shipped in a separate can.
Use only lifting devices appropriated to the pump weight. Check name plate. Do
not use other pump elements than the lifting lug as handles.
2.2 Mounting orientation
See required space on chart 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.
2.3 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.
If the pump has been shelved for over one year, standard maintenance must be
run 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 Leybold.

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.
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 following ambient operating environment must be observed:
■Ambient temperature: 12 °C to 40 °C (54 °F to 104 °F)
■Ambient pressure: Atmospheric pressure. Max. altitude 1000 m absl.
In order to avoid over-heating of the pump, an undisturbed fresh airflow to the
pump is necessary.
The pump must be kept clean (no dust deposit).
3.2 Inlet connection
See safety information 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, com-
pensators 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 least the same
as the diameter of pump’s inlet flange.
When pumping condensable vapours, a gas ballast valve must be used.
3.3 Connection to exhaust side
No isolation or restricting devices should be installed in the exhaust line of the
pump.
Pump exhaust to be connected if oil mist or process gases are to be avoided in
the pump area.
If an exhaust line is installed, it must at least have the same diameter as the ex-
haust 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. Corre-
sponding pressure regulating devices to be installed by the user.
3.4 Oil filling
See safety information page 3.
The necessary LVO120 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.

3.5 电气连接
See safety information page 3.
The electrical installation may only be conducted by a specialist. IEC regulations
have to be followed as well as local or country regulations.
■Voltage and frequency mentioned on the motor nameplate must agree with the
supply voltage.
■The drive motor must be protected against overloads according to IEC 60204-
1 & 61010-1.
■To check the direction of rotation of pumps with three-phase motor, flick the
ON/OFF switch for a short time at atmospheric pressure. If the direction of ro-
tation is not identical with the one indicated by the arrow sticking on the motor
hood, then inverse any two of the electrical phases in the terminal box. Look-
ing at the motor fan cover, the direction of rotation has to be counter clock-
wise.

4 Operation
4.1 Operating advices
See safety information page 3.
When removing condensable vapours, a gas ballast valve must be installed.
The vacuum pump must be run for 30 minutes before operating with condensable
vapours with the inlet connection closed, in order to reach the operating tempera-
ture of about 75 °C. Only up from this operating temperature, condensable va-
pours can be pumped. After use, the pump has to be left running for an additional
30 minutes with the inlet connection closed, to clear the oil of condensate.
Use ear protection in case of operation at high inlet pressures.
Clean eventual oil on the floor.
4.2 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 4.1 (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 2.3.

5.1 Safety Information
Observe all safety regulations.
The vacuum pump must be switched off and secured against accidental switch-on
for all maintenance jobs.
All work must be done by suitably trained personnel. Maintenance or repairs car-
ried out incorrectly will affect the life and performance of the pump and may cause
problems when filing warranty claims.
Never mount used seals ; always mount new seals.
5.2 Maintenance Intervals
The intervals stated in the maintenance schedule are approximate values for nor-
mal pump operation. Unfavourable ambient conditions and/or aggressive media
may significantly reduce the maintenance intervals.

5.3 Leybold Service
Whenever you send us in equipment, indicate whether the equipment is contami-
nated or is free of substances which could pose a health hazard. If it is contami-
nated, 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 Instruc-
tions: “Declaration of Contamination for Compressors, Vacuum Pumps and Com-
ponents”. Another suitable form is available from the Leybold home-page:
www.leybold.com → Downloads → Download Documents → Declaration of Con-
tamination
Attach the form to the equipment or enclose it with the equipment.
This statement detailing the type of contamination is required to satisfy legal re-
quirements and for the protection of our employees.
We must return to the sender any equipment which is not accompanied by a con-
tamination 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 regula-
tions.
5.4 Maintenance Work
A. Oil level
The oil level should be checked at least once a day. If the oil level is below the
“MAX” mark, oil has to be added until the level reaches the mark. If the oil level is
below the “MIN” mark, stop the pump and check it (see chapter 6).
B. Oil changing
See safety information page 3.
Oil must be changed after the first 150 operating hours. Further oil changes, de-
pending on operating conditions (products, vapours, ambient temperature…)
must be done every 500 to 2 000 operating hours or at least every 6 months.
If there is considerable pollution, it could be necessary to change the oil more fre-
quently.
Oil changing must be done with a switched off and still warm pump.
Open the oil drain plug and let run out the used oil into an appropriate container.
Refasten the oil drain plug when oil runs slower, start up the pump briefly (5 sec.
max) and switch off immediately. Reopen the oil drain plug and drain the rest of
the oil. Before refastening the oil drain plug, inspect the O-ring and if necessary
replace it. Open the oil fill plug and pour in clean oil; refasten the oil fill plug. The
pump has to be rinsed out if there is considerable pollution. Therefore pour in
clean oil up to the low edge of the oil level glass, let the pump run briefly (for a
few minutes) then drain the oil again.

C. Exhaust filters replacement
See safety information page 3.
Oil mist escaping form the exhaust during operation indicates that the filter is
probably choked up. Increased motor current could also be the result of a dirty
exhaust filter. Open the exhaust hood, take out the filter and replace it. Also check
the gasket of the exhaust flange and change it if necessary.
D. Checking the oil recovery system
See safety information page 3.
During the exchange of the exhaust filter, check the cleanliness of the foam which
protects the oil return compartment and the oil recovery system. Disassemble the
oil return screw system from the end plate and check the cleanliness of the nozzle
(without disassembling it from the unit). In case of heavy dirtiness, replace the
whole oil recovery screw system.
E. Gas ballast cleaning
See safety information page 3.
If the filter of the gas ballast is dirty, the gas ballast is no longer operative.
The filter has to be replaced (see spare parts list).
F. Inlet flange sifter cleaning
See safety information page 3.
To clean the inlet flange screen, disconnect the inlet flange and clean the screen
with blast air or an appropriate solvent.
G. Anti-suck back valve checking
See safety information page 3.
The anti suck-back valve should be checked at the same time as the inlet
flange screen and if dirty, be cleaned with an appropriate solvent. Also check,
if there is no damage on the sealing part of the valve.
H. Fan cover cleaning
Dirt blockage 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.
