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 must be installed.
1.1 Principle of operation
The SOGEVAC®SV40 B – SV65 B – SV 100 B – SV120 B ATEX Cat 2 are
single- stage, oil-sealed rotary vane pumps. The anti-suckback valve, gas
ballast valve, 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 thru 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 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 is maintained by the pressure difference existing between the oil
casing (pressure above or equal atmospheric pressure) and the intake port
(pressure below atmospheric pressure). On part of the oil is taken from the oil
casing and flows via the oil filter bypass 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 bypass.
A fan running on the motor shaft generates the necessary cooling air. The oil
is also fed, thru a cooling coil, or in case of water cooled pumps, flows
through a water oil heat exchanger controlled by a thermostatic valve.
All SOGEVAC®SV40 B – SV65 B – SV 100 B - SV120 B ATEX Cat 2 pumps
are fitted with:
•PT100 temperature sensor
•Oil level switch
•Oil casing pressure transmitter
Pumps depending of their P/N are equipped with a gas ballast device. If
opened, 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 vapour tolerance specified in the Technical Data) when pumping
condensable gases or vapours. There are different types of gas ballast :
- standard manual gas ballast,
- large gas ballast (10 %), available upon request,
- permanent, available upon request, allowing temperature class T4 inside.
The pump temperature class may vary depending of the GB type. Please
check the pump marking !

130001815_002_C0 SV 40 B – 65 B – 100 B – 120 B ATEX Cat 2 11/2016 6 / 74
Unintentional venting of the vacuum chamber as well as oil suck back when
shutting down the pump are prevented by the integrated anti suck back valve.
This valve is not a safety device and its correct operation & tightness can only
be assured if the valve plate & sealing zone are kept clean and in good
condition.
If all returns are to be avoided by all means, it is required to install a vacuum
safety valve on the pump suction flange. Please consult us.
Inside the pump (process gas)
The inside (process gas side) of this vacuum pump is so designed and
constructed so as not to present an ignition source in cases of expected
malfunction. It is therefore suitable for use in situations in which explosive
atmospheres caused by gases, vapours, mists may occur occasionally in
normal operation (i.e. Zone 1).
The pump and its accessories are not designed for pumping dust, liquids, or
reactive, aggressive or corrosive gases and vapours, explosive or instable
substances, pyrophoric gases, oxidising agents or oxygen enriched
atmospheres (where the concentration of oxygen is greater than 21 vol. %).
Warning
Outside the pump
The outside of this vacuum pump is also so designed and constructed so as
not to present an ignition source in cases of expected malfunction. It is
therefore suitable for use in situations in which explosive atmospheres caused
by gases, vapours, mists may occur occasionally in normal operation (i.e.
Zone 1).
Additionally, the outside of this vacuum pump is so designed and constructed
as to prevent foreseeable ignition sources which can occur during normal
operation and are capable of igniting potentially explosive dust clouds. As
such, when operated within the parameters specified within this instruction
manual, the pump will provide a normal level of protection against the ignition
of potentially explosive dust clouds. It is therefore also suitable for use in
situations in which explosive atmospheres caused by or dust in air are
unlikely to occur or, if they do occur, are likely to do so only infrequently and
for a short period only (i.e. Zone 22).
Places where explosive atmospheres in air may occur are classified in terms
of three zones on the basis of the frequency and duration of the occurrence of
an explosive atmosphere. These are designated Zone 0, 1, 2 where gases,
vapours or mists and Zone 20, 21, 22 where the explosive atmosphere is
caused by dusts. The definitions for these Zones are given in Annex I of the
"ATEX-Directive for users" i.e. Directive 99/92/EC on minimum requirements
for improving the safety and health protection of workers potentially at risk
from explosive atmospheres.
Guidance on how to classify a hazardous area is provided in Directive
99/92/EC and its accompanying Guide (COM (2003)515) together with the
European Standard EN 60079-10 (EN 60079-10 Electrical apparatus for
explosive gas atmospheres Part 10 Classification of hazardous areas). In
addition the Directive 99/92/EC and its Guide provide further information on
explosion prevention and protection. They can be downloaded from the EU
web site: www.europa.eu.int under:

Ignition temperatures of gases / vapours that may be present:
The pump is only suitable for use in situations in which potentially explosive
gas or vapour atmospheres have an ignition temperature greater than 200°C.
Ignition temperatures of gases and vapours can be obtained from the MSDS
(Material Safety Data Sheet).
Ignition temperatures of dusts that may be present:
Dusts that may be present outside the pump must have a cloud ignition
temperature greater than 202,5°C and a layer ignition temperature (5 mm
thick) greater than 210°C The pump shall not be used in areas where
deposits of dusts can be formed. Cloud and layer ignition temperatures of
dusts can be obtained from the MSDS (Material Safety Data Sheet).
Potential Ignition Sources
An Ignition hazard assessment has been carried out according to the
European Standard EN 13463-1. (EN 13463-1 Non-electrical equipment for
potentially explosive atmospheres — Part 1: Basic method and requirements)
This has identified that the following ignition sources may occur during
operation of the pump:
Potential Ignition Sources

Protective measures
Hot surfaces
The compression of gas which occurs during normal operation of a vacuum
pump results in heating and hot surfaces. The SOGEVAC ATEX Cat.2 vacuum
pump has been specially modified and tests have shown that when operated
under the conditions specified in this manual, the internal parts of the pump
which could come into contact with a potentially explosive atmosphere could
reach a maximum temperature of 130°C. The maximum temperature is reached
after continuously operating the pump with an inlet pressure of between
300 mbar and 400 mbar. The actual temperature reached depends on the inlet
pressure. Similarly the outside of the pump could reach a maximum surface
temperature of 130°C (These temperatures include the safety allowances
specified in EN13463-1).
The SOGEVAC ATEX Cat.2 vacuum pumps are fitted with a thermal sensor
(PT100) at the pump stator. This must be connected so that the pump is
automatically switched off if the temperature rises above 115°C which can
happen under mal-operations, e.g. due to blocked oil filters. This should activate
before the pump reaches this maximum temperature and if installed correctly will
automatically stop the pump. The control system should be configured such that
the pump does not automatically restart as the temperature decreases but
should require a manual restart.
NOTE: Higher maximum surface temperatures will occur if the pump is filled and
used with oils other than Leybold type LVO 210. This is caused by the poorer
lubricating and cooling characteristics of other oils in particular PFPE oils.
Hot gases
Hot gases are produced inside the pump due to compression of the gas in
normal operation and are released at the exhaust. These should be ducted to a
safe place.
Mechanical sparks
Mechanical sparks will not occur in normal operation as the internal pump
surfaces are covered with oil. The external cooling fan is designed and
constructed with sufficient clearance to prevent contact and frictional rubbing.
NOTE: Ingress of particles into the pump must be avoided to prevent formation
of hot spots due to rubbing or friction, where necessary a suitable ATEX filter
should be used.
Electrical sparks
The motor and accessories supplied with this pump are certified to the same
classification as the outside of the pump. These should be installed and used in
accordance with the manufacturer's instructions attached to this manual.

Description

130001815_002_C0 SV 40 B – 65 B – 100 B – 120 B ATEX Cat 2 11/2016 9 / 74
Static electricity
The pump should be adequately earthed to prevent the accumulation of static
electricity. This will be achieved if the electrical earth cable to the motor is
properly connected. No hazardous charge generation will occur on the plastic
cooling fan and cowl or on the plastic coupling sleeve in normal operation. (For
further information on hazards from static electricity see CENELEC report
CLC/TR 50404:2003 Electrostatics - Code of practice for the avoidance of
hazards due to static electricity.)
NOTE: Only original Leybold replacement exhaust gas filter cartridges and gas
inlet filter cartridges should be used as these have a special construction to
ensure earthing.
Chemical reactions
The pump should not be used with reactive gases that could produce a
exothermic chemical reaction.
