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 anti­suckback 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 chan­ges 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 slight­ly 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 propor­tion 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 conden­sation (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 m

3

/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 indi­cated 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.
