Important Safety Information
It is mandatory that these operating instructions be read and understood prior
to the vacuum pump installation and start-up.
The SOGEVAC vacuum pumps have been manufactured according to the
newest technical standards and safety regulations. If not installed properly or
not used as directed, dangerous situations or damages might occur.
Under certain operating conditions, dangerous situations may occur when
running the vacuum pump. If this happens, please contact our local office.
Indicate procedures that must be strictly observed to prevent hazards to
persons.
Indicate procedures that must be strictly observed to prevent damage to, or
destruction of the appliance.
The references to figures, e. g. (2/10) consist of the Fig. No. and the item No. in
that order.
We reserve the right to alter the design or any data given in these Operating
Instructions.
When working on the pump system, always observe the Operating Instructions.
Disconnect the unit from the power supply before starting any work. Take
appropriate precautions to ensure 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.
If you send a pump to Oerlikon Leybold Vacuum, indicate whether the pump
is free of substances damaging to health or whether it is contaminated. If it is
contaminated also indicate the nature of hazard.
For this you must use the form we have prepared and which will be provided
upon request.
A copy of this form, «Declaration of Contamination of Vacuum Instruments and
Components» is reproduced at the end of the Operating Instructions.
Please attach this form to the pump, or enclose it with it. This Declaration is
required to meet the law and to protect our personnel.
Oerlikon Leybold Vacuum will return any pump received without a "Declaration
of Contamination" to the sender's address.
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
1.1 Design and function
The SOGEVAC SV300 B are single- stage, oil-sealed rotary vane pumps. The anti-
suckback valve, gas ballast valve (optional), exhaust filter, oil return circuit and
oil cooling oil are integrated functional elements. The pumps are driven by a
directly flanged motor.
The rotor mounted eccentrically in the pump cylinder has three vanes which
divide the pump chamber into several compartments. The volume of each chan-
ges periodically with the rotation of the rotor.
As the rotor rotates, the intake portion of the pumping chamber expands and
sucks gas through the intake port. The gas passes through the dirt trap and the
open anti-suckback valve and enters the pump chamber. As the rotor rotates
further, the vane separates part of the pump chamber from the intake port.
This part of the pump chamber is reduced, and the gas is compressed. At slight-
ly above atmospheric pressure the gas is expelled from the chamber via the
exhaust valve.
Oil injected into the pump chamber serves to seal, lubricate and cool the pump.
The oil entrained with the compressed gas is coarsely trapped in the oil case by
deflection. Then fine filtering occurs in the exhaust filter elements. The propor-
tion of oil in the exhaust gas is thus reduced below the visibility threshold (over
99 % entrapment rate).
Oil trapped in the exhaust filters is returned to the inlet chamber via an oil
return transfer. To prevent gas flowing at atmospheric pressure from the oil
reservoir into the intake port, the oil return line is controlled by a float valve.
The oil cycle is maintained by the pressure difference existing between the oil
case (pressure above or equal to atmospheric pressure) and the intake port
(pressure below atmospheric pressure).The ball bearings are greased for 30 000
hours.
A fan running on the pump shaft generates the necessary cooling air. The oil
cools down through a radiator.
Water cooled pumps with en oil-water heat exchanger and thermostatic valve
are also available (as specific variants).
By opening the gas ballast valve, a controlled amount of air so called «gas
ballast» is admitted into the pump chamber. This gas ballast prevents conden-
sation (up to the limit of water vapor tolerance specified in the Technical Data)
when pumping condensable gases or vapors.
There are different types of gas ballast :
- small gas ballast ( 4 m3/h)
- standard gas ballast ( 7.5 m3/h)
- large gas ballast ( 15 m3/h)
- gas ballast with electromagnetical valve ( 10 m3/h) - See § 2.5.2
On pumps supplied without gas ballast valve, the valve can be retrofitted. The
gas ballast flows are indicative and valid at ultimate pressure.

GA02330_002_06 - 01/2010 - © Oerlikon Leybold Vacuum
Unintentional venting of the vacuum chamber as well as oil suckback when
shutting down the pump are prevented by the integrated anti suck-back valve .
In applications where an oil suckback must be avoided by all means, it is
recommended to install a dedicated valve.
1.1.1 Range of use
SOGEVAC pumps are designed for pumping of inert gases in the range of rough
vacuum, between atmospheric pressure and ultimate pressure of the pump.
SOGEVAC pumps are not designed for pumping of agressive, corrosive,
flammable or explosive gases. By presence of agressive, flammable, corrosive
or explosive gases, contact Oerlikon Leybold Vacuum. These pumps are not
designed for working in flammable or explosive environment.
In case of doubt, contact Oerlikon Leybold Vacuum for the ATEX pump range.
The pumps are not suitable for pumping liquids or media which contain dust.
Corresponding protective measures must be introduced.
In case of doubt, contact Oerlikon Leybold Vacuum.
Before pumping greater than atmospheric concentrations of oxygen (> 20 %)
or other highly reactive gases, the pump must be modified, degreased and a
special oil (such as PFPE) must be used
Take adequate safety precautions. Contact Oerlikon Leybold
Vacuum for important safety instructions.
1.2 Standard Specification
The pump is supplied with drive motor in ready-to-use condition. It is supplied
with GS77 mineral oil, which is filled in.
Specific variants are delivered with different oils. In any case, the oil type is indi-
cated on the pump. No warranty claims could be accepted with use of another
oil than specified.
The connection ports are blanked off by plastic protective caps.
Take these caps away before turning on the pump.

1.7 Lubricants & grease
Unless otherwise specified on the pump, we recommend to run the Sogevac
pumps with GS77 from Oerlikon Leybold Vacuum or an equivalent oil which
meets following requirements and is approved by OLV:
- low vapor pressure, even at high temperatures ;
- flat viscosity curve ;
- minimum water content and absorption ;
- good lubricating properties ;
- resistant to aging under mechanical strain.
If you use a non-approved oil, we cannot guarantee that our pumps will meet
their operating specifications (ultimate pressure, pumping speed, operating
temperature, etc). However, the warranty is voided only if the nonapproved oil
adversely affects the operation or reliability of the pump.
When using other oil brands, employ nondetergent mineral oils of viscosity class
ISO VG68 to ISO VG 100.
Use of other special-grade lubricants for specific applications is possible. Please
consult us.
Only use lubricants and grease which have been fully qualified by Oerlikon
Leybold Vacuum.

1.8 Manipulation and stock
Pumps which have been filled with operating agent must only be moved in
the upright position (horizontally). The angle of slope may not be over 10° max.
Otherwise oil may escape. Avoid any other orientations during transportation.
Check the pump for the presence of any oil leaks, because there is the danger
that someone may slip on the oil which has leaked from the pump. Only use the
lifting lugs which are provided on the pump to lift the pump with the specified
lifting devices.
Caution
Warning
1 3GA02330_002_06 - 01/2010 - © Oerlikon Leybold Vacuum

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) but not below 0°C. Before
taking the pump out of service, it should be properly disconnected from the
vacuum system, purged with dry nitrogen and oil should be exchanged too. The
inlet and exhaust ports of the pump must be blanked off using the shipping
seals which are included upon delivery of the pump. 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 more than one year, standard maintenance
must be run and oil must be exchanged too before the pump is put into service
again. We recommend that you contact the service from Oerlikon Leybold
Vacuum.
2 Operation
2.1 Installation
It is essential to observe the following instructions step by step to ensure a safe
start-up. Start-up may only be conducted by trained specialists.
The SOGEVACs can be set up on any flat, horizontal surface. Under the four feet,
there are metric threaded holes for securing the pump.
The oil level cannot be read properly if the pump is tilted. Pump risks to run
dry. The ambient temperature should be between 12°C (55°F) and 40°C (104°F)
depending on oil type. By modifying the pump or changing the oil type, the
pump can be run at a lower ambient temperature. Please consult us about this.
To ensure adequate cooling of the pump, leave enough space at the air intake
and exhaust points, so as for access and maintenance. Make sure to keep the air
intake of motor clear.
2.2 Connection to system
The standard pump is not suitable for installation in explosion hazard areas.
Please contact us, when you are planning such an application. Before installing
the pump you must reliably disconnect it from the electrical power supply
and prevent the pump from running up inadvertently. The pump must only be
installed by suitably qualified and trained personnel.
Observe all safety regulations.

Operation
2.2.1 Intake Side
The pump has an internally-threaded intake flange. Using suitable connecting
elements (see Fig. 3 and Section 1.4), the pump can be connected to the
vacuum system.
The cross-section of the intake line should be at least the same as the intake
port. If the intake line is too narrow, it reduces the pumping speed.
We recommend applying either LOCTITE or TEFLON tape to the screwed unions
so that they are vacuum-tight (especially if gases are dangerous).
- Pump should be connected to inlet line without any tension. Use flex lines or
pipe unions in your inlet and exhaust lines so that they can be easily removed
for pump maintenance.
- The maximum pressure at the inlet may not exceed atmospheric pressure
(about 1013 mbar). Never operate the pump in the presence of over pressures
at its intake.
- Type of materials used for mounting of canalisations should take care of
pumped gases. It is the same for its tightness.
If the process gas contains dust or particles, it is absolutely essential to install a
dust filter in addition to the dust trap supplied (see Section 1.4). We recommend
to install the dust filter horizontally using the T-piece (3/13) or the elbow (3/14).
This ensures that when removing the filter, no particle falls into the intake port.
You have a choice of four cartridges for the optional inlet filters. The metal
cartridge prevents solid particles such as paper or plastics from entering the
pump ; the paper and polyester cartridges remove small particles such as dust
and powder down to one micron ; the activated carbon cartridge absorbs
chemical vapors of acids, solvents, etc. If the carbon cartridge was stored in a
damp place, bake it for 2 hours at 212°F (100°C) before use.
When pumping vapors, we recommend installing condensate traps or
condensers on the intake side (see Section 1.4).
By pumping of dangerous gases, inlet line must be tight.
No particles or liquids may enter in the pump.
2.2.2 Exhaust Side
The SOGEVACs have integrated exhaust filters which, even at a high gas
throughput, trap the oil mist and guarantee exhaust gas free of oil mist. If
the exhaust filters are clogged, pressure relief valves opens and the filters are
bypassed. As a result, the proportion of oil in the exhaust gas as well as the
pump’s oil consumption rise. Installing new exhaust filters will correct this
problem. (See Section 3.9)
This situation must be resolved by changing the exhaust filters. It is under
utiliser’s responsability to assure maintenance on materiel to avoid any
trespassement of the limits autorised by regulations.
Check in the individual case whether an exhaust line is necessary and/or
prescribed. Volatile substances can pass through the filter. Depending on the
processed gas, we recommend connecting an exhaust line ; this is always
necessary when the exhaust gases are dangerous.
Warning
Warning

1 6 GA02330_002_06 - 01/2010 - © Oerlikon Leybold Vacuum
Observe the safety precautions that apply to your application and process
gases. The pump’s exhaust port also has an internal thread (ET3/18). A hose can
be connected via a suitable screw-in nipple (see Fig. 3 and Section 1.4).
The cross-section of the exhaust line should be at least the same as the pump’s
exhaust port. If the exhaust line is too narrow, overpressure may occur in the
pump.
Before installing the exhaust line, remove the exhaust-flange plate and ensure
that the exhaust demister(s) are secured tightly in place. They sometimes loosen
during shipping and installation. A loose demister results in exhaust smoke
during start-up and operation.
Install the exhaust line with a downward slope to prevent condensate from
flowing back into the pump. If this is not possible, we strongly recommend
installing a condensate trap (see Section 1.5). if several pumps are connected
to one exhaust line, ensure an adequate cross-section and a non-return valve at
the exhaust of each pump.
Never operate the pump with a blocked or restricted exhaust line. Before start-
up ensure, that any blinds or similar shut-off devices in the exhaust line on
the pressure side are opened and that the exhaust line is not obstructed. Such
restrictions reduce the pumping speed, increase the temperature, and could
overload the motor or cause a dangerous overpressure in the pump. Excessive
pressure in the pump could damage the seals, blow out the sight glass, or
destroy the pump housing. In addition to this explosion hazard, excessive
backpressure can result in hazardous process gases leaking out of the pump. If
you are purging the oil casing with inert gas, limit the inert-gas flow. Contact
Oerlikon Leybold Vacuum for recommendations.
When pumping dangerous gases, exhaust line must be tight.
The maximum exhaust pressure must not exceed 1,15 bar (absolute).
Also reliably prevent the occurrence of any blockage in the exhaust line.
Exhaust filter, accessories and the tubing must be rated according to
the maximum throughput. The maximum throughput is equivalent to the
pumping speed of the pumps.
2.3 Electrical Connections
(See fig. 4)
Ensure that incoming power to the pump is off before wiring the motor
or altering the wiring. Electrical connections must be done by a qualified
electrician in accordance with the applicable safety regulations.
Wire the motor for the correct supply voltage via connections in the junction
box. See the wiring diagram on the motor or in the junction box. For proper
connection, a suitable motor protection switch must be used. Set the switch in
accordance with the rating on the motor nameplate. The switch should be of
class 10 at least.

Operation
After connecting the motor and every time you alter the wiring, check the direc-
tion of rotation. Observe the direction arrow on the motor hood. During the
check, the intake port should be open. If the direction of rotation is wrong, oil
may be ejected out the intake port. The vacuum system may be pressurised.
Don’t use the motor fan for checking the rotation direction. The motor fan
rotates too fast to clearly check during operation ; when it slows during shut-
down, it reserves its direction.
Turn off the power supply, and interchange two phases of the connection, if you
need to correct the direction of rotation.
We recommend checking the direction of rotation with a phase-sequence indi-
cator.
Prolonged running of the motor in the wrong direction of rotation will damage
the pump !
A thermal overload switch is available as an accessory. It cuts out the pump if a
specific temperature is exceeded and/or triggers a warning signal.
If any security switch or electrical defect cuts out the pump, re-start-up of the
pump is only possible by hand-action.

2.4 Start-up
Oil for the first filling is supplied with the pump.
Before switching on, always make sure that the pump contains enough oil.
The normal oil level is in the middle of sight glass.
If oil has to be added, unscrew the oil-fill plug, add oil and screw the plug
firmly back in.
The SOGEVAC is designed for normal startup at temperatures over 0°C (32°F)
(as per PNEUROP), depending on used oils.
To avoid overloading the motor, do not start the pump more than six
times within one hour. If frequent starts are needed, the pump should run
continuously and be linked to the vacuum vessel by means of a valve. In
that case, regulation will be made by the valve and not by start/stop of the
pump. With the valve closed, the pump consumes little energy.
-Before starting the pump ensure that the attached accessories meet the
requirements of your application and that safe operation is ensured.
-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.
-The safety regulations which apply to the specific application in each case
must be observed. This applies in particular to installation, operation and
maintenance (servicing) as well as waste disposal and transportation.
Do not lay the hand on the intake to check vacuum.
Exposure of a part of the body to the vacuum result in a rush of blood in the
exposed part.
2.5 Operation
The SOGEVAC can pump gases and vapors, provided that the gas ballast
valve is installed and open and the pump has reached its operating
temperature.
Contact Oerlikon Leybold Vacuum for important safety instructions before
pumping greater than atmospheric concentrations of oxygen or other
highly reactive gases. The pump must be degreased, modified, and special
inert oil must be used for pumping oxygen. Also ATEX variants are available
for pumping explosive gases.
The motor manufacturer guarantees a maximum of 6 starts per hour. To
avoid exceeding 6 starts per hour, run the pump continuously and regulate
the vacuum in your system with a pilot valve.
Pump in operation is hot and some surfaces could reach a temperature
higher than 80°C (176°F). There is a risk of burn by touching. Take note of
warning labels on the pump.

2.5.1 Pumping of Non-condensable Gases
If the process contains mainly permanent gases, the SOGEVACs can be operated
without gas ballast, provided that the saturation vapor pressure at operating
temperature is not exceeded during compression.
If you do not know the composition of the gases to be pumped, and if you can’t
rule out the possibility of condensation, run the pump with gas ballast valve
open in accordance with Section 2.5.2.
2.5.2 Pumping of Condensable Gases and Vapors. Using gas ballast.
The pumps with gas ballast valves are delivered with the gas ballast valve open.
The SOGEVAC SV300 B can be equipped with following types of gas ballasts :
-Standard gas ballast . This gas ballast corresponds to the most important
part of applications .
- Gas ballast «big flow» as a variant or accessory is intended for the
applications where more vapours of condensable gases could come into the
pump.
- Gas ballast "small flow" for pumping on applications where only few vapours
are to be pumped and where the ultimate pressure with open gas ballast is
important.
- Gasballast with E.M. valve (Cat. No. upon request) This kit is intended
for being mounted on pumps on which the gasballast can be driven by an
electromagnetic valve applied at 24 VDC.
A gas ballast kit Including all material required for changing the manual gas
ballast flow to "small", "standard"or "big" is available: P/N 9 714 64 130
With the gas ballast valve open and at operating temperature, the SOGEVAC's
can pump pure water vapor up to the water vapor tolerance indicated in the
Technical Data. The pump’s water vapor tolerance can be increased by raising
the operating temperature.
Use a screwdriver to open the gas ballast valve. The running noise of the pump
is slightly louder when the gas ballast valve is open. Before opening the pump
to vapors, ensure that the gas ballast valve is open and that the pump has been
warmed up for about 30 minutes with closed intake line.
Important
Do not 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, slowly open the
intake line, after reaching the operating temperature to prevent excessive
quantities of vapor entering the pump.
One sign of condensation of vapors in the pump is a rise in the oil level during
operation of the pump.
During pumping, vapors may dissolve in the oil. This changes the oil properties
and causes a risk of corrosion in the pump. Therefore, do not switch off the
pump immediately after completion of the process. Instead, allow the pump to
continue operating with the gas ballast valve open and the intake line closed
until the oil is free of condensed vapors. We strongly recommend operating the
pump in this mode for about 30 minutes after completion of the process.
