1 Introduction
This quick guide will assist you in starting up the unit. Follow
the safety notices or injury to health or property damage may
occur. Carefully read the original operating instructions in-
cluding information on maintenance and troubleshooting
prior to startup. These are located on the included CD and on-
line at

manufacturer reserves the right to change performance-, spe-
cification- or technical data without prior notice. Please keep
these instructions for future reference.
1.1 Intended use
P2.x AMEX sample gas pumps are intended for installation in
gas analysis systems for industrial applications to transport
gaseous media only. They are not suitable for liquids. The
sample gas pumps are not designed to be used outdoors
without protection from weather effects.
The AMEX versions are suitable for use in Class I, Div. 2,
Groups B, C, D, temperature classes T3/T3C; they are not suit-
able for use in dusty areas.
The complete designation of the P2.x AMEX sample gas pump
is:
NI / I / 2 / BCD / T3, T3C
CL.I Div.2 Gr BCD T3, T3C
DANGER! Explosion hazard when used in explosive areas
The sample gas pumps must not be used in dusty areas or in
areas other than the designated explosive area.
If the specifications in these operating instructions are ob-
served, in particular the temperature parameters in the tech-
nical data, the P2.x AMEX sample gas pumps can convey non-
flammable and also flammable gaseous media, which can oc-
casionally be explosive in normal operation.
The delivery of highly particle-laden, explosive gas mixtures
can lead to a dangerous electrostatic charge in the bellows/
pump body. Install particle filtration with the appropriate
fineness upstream from the pump gas input. For the
P2.x AMEX-O2 versions in particular, we recommend a filter
fineness of <10 µm.
The maximum surface temperature varies according to the
medium and ambient temperatures. Please refer to the tech-
nical data in the Appendices to see the correlation between
media temperature, ambient temperature and the pump's
temperature class.
The pump head and the drive motor on the P2.4 AMEX/
P2.84 AMEX sample gas pump are isolated for use in hot ap-
plications. The sample gas pump has a split adapter which
can be mounted with one half inside a heated cabinet while
10 Bühler Technologies GmbH
the other half mounted on the outside supports the drive mo-
tor. In doing so, wall thicknesses of up to 30 mm can be
bridged without additional modifications.
Applications where sample gas is still moist can result in con-
densation in the lines and the pump body. In these cases, the
pump head must be suspended (see item Alteration of
hanging pump bodies).
Sample gas pumps P2.x AMEX-O2 (item no.: 42.............-O2) are
optimised especially for use with increased oxygen concentra-
tions with regard to the parts in contact with the medium.
Only BAM (Federal Institute for Materials Research) tested ma-
terials are used. Special cleaning of the components to minim-
ise organic and inorganic contamination is mandatory. Manu-
facturing the products under controlled cleanliness condi-
tions ensures compliance with the limit values in accordance
with EIGA Doc 33/18.
Sample gas pumps P2.x AMEX-H2 (item no.: 42.............-H2) are
specially refined using advanced manufacturing measures, in
particular to prevent hydrogen-induced component damage.
In addition, the parts in contact with the media are subjected
to an additional visual inspection to remove any residual
metallic contamination, such as chips and particles. Finally, a
leak test is carried out as standard.
Please note the information in the Appendices to this manual
on the specific intended use, existing material combinations,
as well as pressure and temperature limits of the various
models. In addition, please also note the specifications and
markings on the nameplates.
1.2 Specific conditions of use
It is the responsibility of the installer to ensure that the com-
bination of ambient temperature and process heating does
not exceed the maximum specified ambient temperature rat-
ing of 40 °C at the motor.
