Emphasises additional application information and other useful information
provided within these Operating Instructions.
The Leybold Sogevac® SV40 B - SV65 B - SV100 B has been designed
for safe and efficient operation when used properly and in accordance
with these Operating Instructions. It is the responsibility of the user to
carefully read and strictly observe all safety precautions described in this
section and throughout the Operating Instructions. The Sogevac® SV40
B - SV65 B - SV100 B must only be operated in the proper condition
and under the conditions described in the Operating Instructions.
It must be operated and maintained by trained personnel only. Consult
local, state, and national agencies regarding specific requirements and
regulations. Address any further safety, operation and/or maintenance
questions to our nearest office.
Failure to observe the following precautions could result in serious
personal injury!
Sogevac® pumps are not designed:
■ for pumping of dusty, aggressive, corrosive, flammable or explosive gases
or gases mixtures,
■ for pumping of oxygen with a greater concentration than atmospheric
concentration (>20%) or other highly reactive gases
■ for working in flammable, explosive or dusty environment.
For all these cases, special materials must be used. In case of doubt, please
contact Leybold.
See also the limits of use indicated in the CE declaration of conformity.
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.
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.
Depending on the process involved, dangerous substances and oil may
escape from the pump. Take the necessary safety precautions!

Disconnect the unit from the power supply before starting any work.
Take appropriate precautions to insure that the pump cannot start.
If the pump has pumped hazardous gases it will be absolutely necessary to
determine the nature of the hazard involved and take the appropriate safety
precautions.
Observe all safety regulations!
Take adequate safety precautions prior to opening the intake or exhaust port.
Failure to observe the following precautions could result in damage to
the equipment!
Liquid and solid particles must not enter the pump. Install the adequate
filters, separators and/or condensers. In case of doubt consult Leybold.
The intake line of the pump must never be connected to a device with over
atmospheric pressure. Design the exhaust line so that no pressure higher
than 1,15 bar abs. (0,15 bar rel.) can occur.
Operating of the pump without oil or operating with incorrect direction of
rotation can destroy the pump.
Never use discarded seals. Always assemble using new seals.
Respect the instructions concerning environment protection when discarding
used oil or exhaust filters!
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.

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 vapours, a gas ballast valve must be installed.
1.1 Principle of operation
The Sogevac® pumps SV40 B, SV65 B and SV100 B 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, which retains > 99,9
% of the oil 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 pressures. Some pumps are
equipped with an oil filter.
Pumps are available with or without gasballast, with corresponding catalog
numbers.
At pump switch off, an anti suck-back valve (ASBV) closes the pump inlet
and avoids pump oil be sucked into the chamber.
For this, the ASBV must be kept clean and in good condition.

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.
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.
For SV40 B and SV65 B, the necessary oil is supplied in a can beside the
pump. For the SV100 B, the oil is filled in.
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.
Use only lifting devices appropriated to the pump weight. Check name plate.
Do not use other pump elements than the lifting lugs as handles.
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.
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 exchange
too. The gas ballast must be closed and if the pump is to be shelved for a
longer period of time is 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 Leybold.

3.1 Setting up
The pump must be set up or mounted horizontally on a flat surface. Special
mounting is not required. For indoor use only up to 1000 m altitude.
The following ambient operating environment must be observed:
■ Ambient temperature: 12 °C to 40 °C (54 °F to 104 °F),
■ Rel. humidity (without condensation) ≤ 95 %
■ Ambient pressure = Atmospheric pressure.
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 Connection to system
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 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.
■ Inlet pressure must not exceed atmospheric pressure.
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).
The maximum exhaust pressure must neither exceed 1.15 bar absolute (0.15
bar relative), nor fall under atmosphere pressure minus 15 mbar.
Pump exhaust to be connected if oil mist or process gases are to be avoided
in the pump area.
Corresponding pressure regulating devices to be installed by the user.

Voltage and frequency mentioned on the motor nameplate must agree with
the supply voltage.
To check the direction of rotation of pumps, flick the ON/OFF switch. 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 electrical phases in
the terminal box. Looking at the motor fan cover, the direction of rotation has
to be counterclockwise.
3.3 Electrical connections
Ensure that incoming power to the pump is off before wiring the motor or
altering the wiring.
Electrical connection work must only be carried out by a qualified electrician
in accordance with the applicable safety rules, see IEC 60204-1 & IEC
61010-1.

3.4 Oil filling
For SV40 B and SV65 B, the necessary oil is supplied in a can beside the
pump.
For the SV100 B, the oil is filled in.
To fill in the oil, unscrew the oil fill plug (48 for SV40 B and SV65 B, 52 for
SV100 B) and fill in until the oil level reaches the “MAX” mark beside the oil
sight glass.
3.5 Start-up
The pumps are supplied with the necessary oil filling in ready-to-use
condition. Always verify proper oil level before operating the pump.
The pump is designed for fail-safe start-up at temperatures over 12 °C (55 °F)
(as per PNEUROP).
If local regulations provide a WYE-DELTA starting connect the pump to the
system so that it can start loadfree, i.e. at atmospheric pressure in the intake
port. If the vacuum system is not to be vented further measures will be
necessary, e.g. a starting valve can be mounted.
Please contact us in this case.
The signals of the oil level switch and exhaust filter over pressure switch must
be delayed (timer) on the pump switch-on for approx. 1 minute.

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.
Use ear protection in case of operation at high inlet pressures
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 opened by a screwdriver. 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; 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 opened 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.
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.
