Important Safety Information
Indicates procedures that must be strictly observed to prevent hazards to
persons.
Indicates procedures that must be strictly observed to prevent damage to, or
destruction of the product.
Emphasises additional application information and other useful information
provided within these Operating Instructions.
The Oerlikon Leybold Vacuum Sogevac® SV630 B - SV750 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®
SV630 B - SV750 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 aggressive, corrosive, flammable or explosive gases or
gases mixtures ;
■ for pumping of oxygen or other highly reactive gases with a greater
concentration than atmospheric concentration (>20%) ;
■ for working in flammable or explosive environment.
For all these cases, special materials must be used. In case of doubt, please
contact Oerlikon Leybold Vacuum.
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 !
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 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 Oerlikon
Leybold Vacuum.
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.
We reserve the right to alter the design or any data given in these Operating
Instructions. The illustrations are not binding.

1 Description
SOGEVAC® pumps are designed for pumping of inert gases in the range
of rough vacuum, between atmospheric pressure and end pressure of the
pump.
When removing condensable vapours, a gas ballast valve (or 2) must be
installed.
1.1 Principle of operation
The SOGEVAC® SV630 B / SV750 B is a single-stage, oil-sealed rotary vane
pump.
The anti-suckback valve, gas ballast valve, exhaust filters, oil feedback
circuit, oil cooler and thermal switch are integrated functional elements of the
SV630 B. The pump is driven by a foot-mounted motor via four V-belts.
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 a result of enlargement of the pump chamber that is open in the direction
of the intake port, gas is sucked in. The gas passes through the dirt trap
and the open antisuckback 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 valves.
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 bottom
part of the oil casing. Then fine filtering occurs in the 8 integrated exhaust
filter elements.
The oil trapped in the exhaust filters is returned to the stator via an oil return
line. 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 of the SOGEVAC® SV630 B is maintained by the pressure
difference existing between the oil casing (pressure above atmospheric
pressure) and the intake port (pressure below atmospheric pressure).
Unintentional venting of the vacuum chamber as well as oil suckback when
switching off the pump are prevented by the built-in anti-suckback valve.
Nevertheless, the anti-suckback valve does not guarantee the same safety as
one valve.
As an additional failsafe device a thermal switch is incorporated ; it measures
the temperature in the main oil cycle before the oil is injected into the pump
chamber.

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.
The SV630 B, SV750 B, have the GS77 (He-200) mineral oil 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.
Make sure that these have been installed safety. Use suitable lifting
equipment. Make sure that all safety regulations are observed..
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) 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. Drain the water from the cooling circuit (See § 3.2). 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 Oerlikon Leybold Vacuum.
