Product Description
Use
The vacuum pump is intended for
−
the suction
of
−
mixtures of dry, non-aggressive and non-toxic gases and/or
dust according to the identification on the nameplate of the
vacuum pump (explanation see below).
Conveying media with a lower or higher density than air leads to an
increased thermal and/or mechanical load on the vacuum pump and
is permissible only after prior consultation with Busch.
Max. allowed temperature of the inlet gas: 40 °C
According to the directive
2014/34/EU
(“ATEX
2014
”) the
vacuum pump is made for the intended use in potentially
explosive areas according to the data given on the nameplate
of the vacuum pump and on the data given on the nameplate of
the drive motor.
This requires a separate consideration of the conveyed gas/air or
dust/air mixtures on the one side and the environment of the vacuum
pump on the other. On the nameplate of the vacuum pump the
classification with regard to the conveyed gas/air or dust/air mixtures
is marked with an “inside”, while the classification with regard to the
environment is marked with an “outside”. The classification of the
motor always refers to the environment.
In case Busch delivered the vacuum pump/ compressor without
drive motor or a replacement motor is to be mounted or for
economic reasons the vacuum pump was equipped with a simpler
motor, the following must be observed:
In case the classifications of the vacuum pump and of the drive
motor are different the inferior classification is relevant. This
means also that the vacuum pump is suitable for the placement
in a potentially explosive environment only if both the vacuum
pump, the coupling and the drive motor are approved to the
required extent for use in potentially explosive areas.
Depending on the version the approval is valid only together
with certain standard or optional components, or is limited by
the use of certain optional components, as described below
and in the chapter Operational Options / Use of Optionally
Available Equipment (

page 4).
The classification on the vacuum pump is to be read as follows
(interpretations of equipment categories and zones for information
only; the relevant laws, directives and standards are literally binding;

inside = in this line classification for explosive atmosphere
inside the vacuum pump
II 2G IIB3 TX = in the process gas explosive atmosphere
consisting of a mixture with air of flammable substances in the form
of gas likely to occur in normal operation occasionally;
if the process gas contains dust, also if the dust is not combustible,
the use of a special ATEX-inlet air filter (with equipotential bonding)
is required; temperature monitoring is required (resistance
thermometer and temperature-transmitter in standard scope of
delivery);
II 3G IIB3 TX = in the process gas explosive atmosphere consisting
of a mixture with air of flammable substances in the form of gas not
likely to occur in normal operation but, if it does occur, will persist for
a short period only;
