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 SV200 and SV300 BR2 are single-stage oil-sealed
rotary vane vacuum 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 (7/88), mounted eccentrically in the pump cylinder (7/83), 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 thru the intake port. The gas passes through the dirt trap and the
open anti-suckback valve (7/54) 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 (6/28).
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
(6/27) by deflection. Then fine filtering occurs in the exhaust filter elements
(6/29). The proportion of oil in the exhaust gas is thus reduced below the
visibility threshold (over 99.9 % entrapment rate).
Oil trapped in the exhaust filters is returned to the inlet chamber via an oil
return line (6/11).
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 egual atmospheric pressure) and the intake port
(pressure below atmospheric pressure). One part of the oil is taken from the
oil reservoir (6/27) and flows via the oil filter (6/25) to the bearing points of
the rotor and to the pump chamber. The other part of oil injected in the pump
does not run through the oil filter. So, if the oil filter is accidently completely
clogged, lubrification will be assured through the second circuit with enough
quantity of oil to guarantee the good mechanical running of the pump.

6GAET02307_002_10 - 06/2008 - © Œrlikon Leybold Vacuum
Description
However, in that case, the pump will not reach anymore its specific end
pressure. That will often indicate that oil is polluted and/or oil filter is clogged.
A fan running on the motor shaft generates the necessary cooling air.
The oil is also fed, thru a cooling coil.
Upon request, water cooled with heat exchanger and thermostatic valve can
be delivered. Those pumps are delivered with a dedicated instruction manual
adder.
Pump can be ordered with gas ballast device, on request (6/14). 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 vapours.
There are different types of gas ballast:
- standard gas ballast < 7 Nm3/h,
- large gas ballast 18 Nm3/h,
- gas ballast with electromagnetical valve 24 VDC, 18W, 7 Nm3/h.
The operational limits of gas ballast are defined in § 4.1.
On pumps supplied without gas ballast valve, the valve can be retrofitted
(see § 1.4 and 4.4).
Unintentional venting of the vacuum chamber as well as oil suckback when
shutting down the pump are prevented by the integrated antisuckback valve
(7/54), see also § 4.2.

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-adhe-
sives. Take these caps or self-adhesives away before turning on the pump.
For SV200 and SV300, the pump is supplied with drive motor in ready to use
condition ; it is supplied with GS77 (on equivalent) oil.
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.
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.
2.3 Storing
If the pump is to be shut down for an extended period or if the pump has to
be stored, proceed as follows :
When pumping harmful substances, take adequate safety precautions.
Drain the oil (see § 5.4-C).
Pour in clean oil up to the bottom edge of the oil-level glass (see § 5.4-C)
and let the pump run for a few minutes.
Then drain the oil and pour in clean oil up to the top edge of the oil-level
glass (see § 5.4-C).
Seal the connection ports. Special preservation or slushing oils are not
necessary.

3 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 standard pump is not suitable for installation in explosion hazard areas
ATEX. Please contact us, if 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.
Observe all safety regulations.
3.1 Setting up
The pump 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 risk to run
dry and oil level switch may not react correctly.
The Sogevac®pump can pump gases and vapours, provided that the gas
ballast valve is installed and open and the pump has reached its operating
temperature.
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.
Observethesafetyregulations.
Inlet connection
See safety instructions page 3.
The pump has an internally-threaded intake flange. Using suitable connecting
elements (see § 1.3), 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 when 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.
■The inlet pipe should be installed with a rising slope towards the pump to
avoid condensates flowing into the pump.
If the process gas contains dust, it is absolutely essential to install a dust
filter in addition to the dust trap supplied (see § 1.3).

Warning
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 particles fall
into the intake port.
When pumping vapours, we recommend installing condensate traps on the
intake and exhaust sides (see § 1.3).
By pumping of dangerous gases, inlet line must be tight.
No particles or liquids may enter in the pump.
Exhaust Side
The Sogevac®pumps 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 open and the filters are
bypassed. As a result, the proportion of oil in the exhaust gas as well as the
pump oil consumption rise.
This situation must be resolved by changing the exhaust filters. It is under
user’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 process gas, we recommend connecting an exhaust line; this is always
necessary when the exhaust gases are dangerous.
Observe the safety precautions that apply to your application and process
gases. The pump’s exhaust port also has an internal thread . A hose can be
connected via a suitable screwing nipple (see § 1.3).
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.
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 § 1.3). 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 open and that the exhaust line is not obstructed.
By pumping of 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 pump.
Should a fored ventilation extraction be installed, the pressure in the exhaust
pipe shall not be lower than atm.pressure minus 50 mbar.

3.2 Electrical Connections
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.
After connecting the motor and after every time you alter the wiring, check
the direction of rotation. Observe the direction arrow on the motor hood.
When checking, 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
shutdown, it reserves its direction.
Briefly switch ON the pump, check if you can feel suction at the inlet port,
and immediately turn off the pump. When the pump is rotating correctly, you
should feel suction at the inlet port.
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
indicator.
