• Before operating the TRIVAC E with atmospheric gas ballast (optional) check first compatibility with the
pumped media so as to avoid hazardous conditions during operation right from the start.
• Before commissioning the TRIVAC E, make sure that the media which are to be pumped are compa-
tible with each other so as to avoid hazardous situations.
All relevant safety standards and regulations must be observed.
• It is recommended to always operate the TRIVAC E with a suitable exhaust line which is properly
connected. It must slope down and away from the pump.
• When moving the TRIVAC E always use the allowed means.
A lifting eye is provided as standard on the pump.
Failure to observe the following precautions could result in damage to the pump:
• Do not allow the ingestion of small objects (screws, nuts, washers, pieces of wire, etc.)
through the inlet port. Always use the screen which is supplied with every pump.
• Do not use the pump for applications that produce abrasive or adhesive powders or
condensable vapours that can leave adhesive or high viscosity deposits. Please contact Leybold Sales
or Service to select a suitable separator. Also pease contact Leybold Sales or Service when planning
to pump vapours other than water vapour.
• This pump is suited for pumping water vapour within the specified water vapour tolerance limits.
• Avoid vapours that can condense into liquids upon compression inside the pump, if these substances
exceed the vapour tolerance of the pump.
• Before pumping vapours, the TRIVAC E should have attained its operating temperature, and the gas
ballast should be set to position I - III (position 0 = closed, position 3 = max. water vapour tolerance,
30 mbar).
The pump will have attained its operating temperature about 30 minutes after starting the pump. During
this time the pump should be separated from the process, by a valve in the intake line, for example.
• In the case of wet processes we recommend the installation of liquid separators upstream and down-
stream of the pump as well as the use of the gas ballast.
• The exhaust line should be laid so that it slopes down and away from the pump so as to prevent con-
densate from backstreaming into the pump.
• The entry of particles and fluids 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.
This information will help the operator to obtain the best performance from the equipment:
• Normal amounts of humidity within the range of the pump’s vapour tolerance will not significantly affect
pump performance when the gas ballast is active. Preferably use the exhaust flange located on the side
of the motor.
