2 Important safety information
2.1 Mechanical hazards
WARNING: BLOCKED EXHAUST
Risk of injury or damage to the equipment. If exhaust gases are collected or
contained, the exhaust line may get pressurised. Make sure that the gas ow from
the exhaust port is not blocked or restricted in any way.
The pressure in the oil box must not exceed 0.5 bar(g). An exhaust line too small in
diameter or which is blocked can result in overpressure within the pump. The pump
may get damaged or burst if the pump is opened. So the exhaust line must be
checked from time to time to make sure that there are no obstructions.
Design the exhaust line so that the pressure does not reach above 1.15 bar absolute
(0.15 bar relative). The pressure regulation device must be installed by the end-user.
We recommend to treat the gases from the pump exhaust in function of their nature.
▪Do not expose any part of the human body to the vacuum as this can
cause injury.
▪Do not step on the pump.
▪Do not operate the pump without connecting the intake line or without
tting a blank ange.
▪Do not open vacuum connections, oil lling plug and oil draining valve
during operation of the pump as there is a risk of serious injury.
▪The location at which the pump (including its accessories) is being
operated must not have an angle more than 10 degrees from the
vertical. Check that the inclination of the pump is less than 10 degrees
from the vertical. Select the operating place so that all controls are
easily accessible.
▪Move the pump lled with oil only in its vertical position. Spilt oil
involves the risk of falling.
▪Take adequate safety precautions before you open the intake or
exhaust port.
▪Do not connect the intake line of the pump to a device with over
atmospheric pressure.
▪Operating the pump without oil or operating with incorrect direction of
rotation can damage the pump.
▪Do not use discarded seals. Always assemble using new seals.
▪Follow the instructions concerning environmental protection to discard
used oil.
▪Touch the inner sections of the pumps only while wearing clean gloves
and use clean tools, do the necessary work in clean and dry rooms.
▪Do not allow the ingestion of any objects for example-screws, welding
beads, nuts, washers, pieces of wire, ttings etc. through the intake
port of the pump. Objects falling into the pump can cause severe
damage.
▪To move the pump always use suitable transport means.

Tagout) the equipment. Observe the national regulations for example - EN 50110-1
for Europe.
WARNING: AUTOMATIC RESTART
Risk of injury or damage to the equipment. After a mains power failure, the pump will
operate automatically again. This also applies in the case of an emergency shut-
down. To prevent the pump from operating automatically, the pump must be
integrated with a control arrangement such that it can only be switched on manually
after the mains power has returned.
▪Always operate the pump with a properly connected protective earth
conductor and make sure that the motor terminal box is closed.
▪Lay electric feed lines so that there is no risk of tripping.
▪Lay the connecting lines so that the connecting lines do not get
damaged. Protect the lines against humidity and contact with uids.
Avoid thermally stressing the lines by unfavourable laying. Provide
strain relief for the connecting lines so that the plugs and the line
connectors are not subjected to excessively high mechanical stresses.
▪Take appropriate precautions to make sure that the pump does not
start while laying electric feed lines.
2.3 Thermal hazards
WARNING: HOT SURFACE
Risk of burn. During normal operation, the pump surface temperature can reach
above 70 °C (158 °F). There is a risk of getting burns. Note the symbols on the pump
indicating the hazards. If the pump is hot, wear the required protective clothing. All
the work must be done using protection gloves if the pump is still warm.
▪Handle the pump only after venting and after it cools down.
▪Do not remove the oil-ll or oil-drain plugs while the pump is operating.
There is a risk of suffering burns. Always wear protective gloves and
protective goggles for protection against the oil.
▪Note the warning information on the housing surface. If these warning
notices have been removed, covered or obstructed, include
corresponding additional warning information.
2.4 Hazards caused by materials and substances

Important safety information

WARNING: CONTAMINATION HAZARD
Risk of toxic exposure. Contaminated parts can be detrimental to health and the
environment. Before beginning with any work, nd out whether any parts are
contaminated. Adhere to the relevant regulations and take the necessary precautions
when handling contaminated parts.
▪Liquid and solid particles or dust must not enter the pump. Install the
adequate lters, separators and/or condensers. In case of doubt
consult us.
▪The pump must be packaged in such a way that it will not be
damaged during shipping so that no harmful substances can escape
from the package.
▪The vacuum and exhaust lines must be leak tight. Hazardous process
gases may escape or the pumped gases can react with air or
atmospheric humidity. After installation of the pump and after servicing
work on the vacuum system, leak detection is necessary.
When pumping hazardous gases we recommend to do leak detection
regularly. Leaks in the pump cannot be ruled out under all
circumstances. When pumping hazardous gases, the operator must
make sure that leaks at the pump and in the vacuum system will not
be a hazard.
▪Since all application related hazards for vacuum systems cannot be
described in detail in these operating instructions, we have a separate
document (safety booklet) available in which the hazards and general
safety concepts for design, operation and maintenance of vacuum
systems are explained.
When planning to pump hazardous substances with this pump, read
the related chapters in the safety booklet and these operating
instructions rst. You can download the safety booklet from our
homepage.
▪The pump is not suitable for oxygen pumping operation.
▪Before commissioning the pump, make sure that the media which are
to be pumped are compatible with each other to avoid hazardous
situations. All relevant safety standards and regulations must be
observed.
▪If the pump has previously handled hazardous gases, implement the
proper precautionary measures before opening the intake or exhaust
connection. Before opening the pump, purge it for a longer period with
an inert gas. If necessary, use gloves, a respirator and/or protective
clothing and work under an exhaust hood. Firmly seal off the pump.
When shipping the contaminated pump for servicing, also state the
type of hazard. Refer to Service on page 49 for more details.
▪When cleaning a system in which a pump has been integrated, all
parts in contact with the medium need to be compatible with the
cleaning agent to prevent a chemical reaction. Residues of the
cleaning agent within the pump must be avoided.
▪The pump is not suitable for operation in the explosion hazard areas.

2.5 Danger of ignition
WARNING: IGNITION HAZARD
Risk of injury or damage to the equipment. The pumps including the accessories are
not suitable for pumping combustible and explosive gases or vapours.
2.6 Hazards caused by noise
CAUTION: NOISE HAZARD
Risk of injury. The noise level produced by the pump is less than or equal to 60 dB(A).
Suitable hearing protection measures must be used while working.
2.7 Risk of damage to the pump
▪Before starting up for the rst time, the motor circuit must be equipped
with a suitable protective motor switch. Take note of the information in
these operating instructions and on the electric motor (wiring diagram).
▪Do not allow the ingestion of small objects (screws, nuts, washers,
pieces of wire, etc.) through the inlet port. So always use the inlet
screen which is supplied as standard.
▪Do not use the pump for applications that produce abrasive or
adhesive powders or condensable vapours that can leave adhesive or
high viscosity deposits. When planning to pump vapours other than
water vapour, contact our sales or service department for advice.
▪This pump is suitable for pumping water vapour within the specied
water vapour tolerance limits.
▪Avoid vapours that can condense into liquids when being compressed
inside the pump, if these substances exceed the vapour tolerance of
the pump.
▪Before pumping vapours the pump must attain its operating
temperature. It takes approximately 30 minutes for the pump to attain
its operating temperature after the pump is started. During this
warming up phase, the pump must be separated from the process, for
example, by a blocking valve in the intake line.
▪In the case of wet processes, we recommend the installation of liquid
separators upstream and downstream of the pump as well as the use
of the gas ballast.
▪The exhaust line must be laid so that it slopes down and away from
the pump to prevent condensate from backstreaming into the pump.
▪The entry of particles and uids must be avoided under all
circumstances.
▪Reactive or aggressive substances in the pump chamber may impair
the operating oil or modify it. In addition, such substances may be
incompatible with the materials of the pump (viton, grey cast iron,
aluminium, steel, resins, glass etc.).
▪Corrosion, deposits and cracking of oil within the pump are not
allowed.

3 Description
WARNING: EXPLOSION HAZARD
Risk of injury and damage to the equipment. The pump must not be installed and
operated within explosion hazard areas.
The TRIVAC L pumps are two-stage, oil sealed, sliding-vane vacuum
pumps.
The pump is designed for pumping inert gases in the range of medium
vacuum, between atmospheric pressure and the ultimate pressure of the
pump. When removing condensable vapours, a gas ballast valve must be
opened.
TRIVAC L pumps are capable of pumping gases, vapours and evacuating
vessels or vacuum systems down into the medium vacuum range. The
standard version of the pump is not suitable for pumping oxygen exceeding
25% and for pumping hazardous substances or aggressive or corrosive
gases.
Through an intermediate ange, a four-pole three-phase motor is mounted
to the coupling housing. The pump and motor shafts are directly connected
by a exible coupling. The oil-level glass, drain valve and nameplate are
arranged on the same side. All vacuum connections are default on the top of
the pump.
3.1 Principle of operation
The pump is an oil-sealed rotary vane pump. The anti-suck back valve, gas
ballast valve and oil return circuit are integrated functional elements. The
pump is driven by a directly anged motor.
The rotor, mounted eccentrically in the pump housing, has two radially
sliding vanes which divide the pump chamber into several compartments.
The volume of each compartment changes periodically with the rotation of
the rotor.
As a result, gas is sucked in at the intake port. The gas passes through a
dirt trap sieve and open the anti-suck back valve, then enters the pump
chamber. In the pump chamber, the gas is passed on and compressed after
the inlet aperture is closed by the vane.
The oil injected into the pump chamber is used for sealing and lubricating.
The slap noise of the oil in the pump which usually occurs when attaining
the ultimate pressure is prevented by admitting a very small amount of air
into the pump chamber.
The compressed gas in the pump chamber is ejected through the exhaust
valve. The oil entrained in the gas is coarsely separated by the exhaust
cover. There the oil is also freed of mechanical impurities. The gas leaves the
pump through the exhaust port.
During compression, a controlled amount of air – the so-called gas ballast –
can be allowed to enter the pump chamber by opening the gas ballast
valve. The gas ballast stops the condensation of vapours in the pump
chamber up to the limit of the water vapour tolerance as specied in the
technical data for the pump.
The gas ballast valve is opened (position I and position II) and closed
(position 0) by turning the gas ballast knob on the front.
