Failure to observe the following precautions could result in dama-
ge 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 spe-
cified water vapour tolerance limits.
■
Avoid vapours that can condense into liquids upon compres-
sion inside the pump, if these substances exceed the vapour
tolerance of the pump.
■
Before pumping vapours, the TRIVAC BCS (PFPE) should have
attained its operating temperature, and the gas ballast should
be set to position I (position 0 = closed, position I = max. water
vapour tolerance, 25 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 downstream 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 condensate from back-
streaming into the pump.
■
The entry of particles and fluids must be avoided under all cir-
cumstances.
■
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.
■
Normal amounts of humidity within the range of the pump’s
vapour tolerance will not significantly affect pump performan-
ce when the gas ballast is active.
In the case of custom pumps (with a Part No. deviating from
the Part No. stated in the EC Declaration of Conformity)
please note the information provided on a separate sheet.
