1.1 Intended use

Sample gas pumps are intended for installation in gas ana-
lysis systems for industrial applications.
DANGER
Danger of explosion if used in a potentially explosive
atmosphere
Sample gas pumps of types P2.3C and P2.4C are not suitable
for use in potentially explosive atmospheres and must not be
placed in them.
The complete designation of the P2.3C and P2.4C sample gas
pumps is:
II 3G/- c IIB T4 X
The P2.3 C and P2.4C sample gas pumps may only be used to
convey explosion class IIA and IIB flammable gaseous media
which are not explosive during normal operation, as well as
non-flammable gaseous media.
The maximum surface temperature varies by the medium
and ambient temperatures. Please refer to the data sheets for
the correlation between media temperature, ambient tem-
perature and the pump's temperature class. Flammable medi-
ums must not be heated beyond these values. Please note,
flammable gas must only be heated up to 80 % of its ignition
temperature. The lower of the two values is the maximum
medium temperature.
Gas sampling is generally prohibited if the gas flow results in
a dangerous electrostatic charge in the bellow / pump body
(also see chapter "Operation and Control").
The sample gas pumps are only intended to convey gaseous
media. They are not suitable for liquids.
Please note the additional information in chapter "Product
Description" and "Operation and Control" along with the in-
formation on specific intended use, existing material combin-
ations, as well as pressure and temperature limits in the data
sheets.

Product documentation
2 Safety regulations
Installation into a complete system can pose new hazards on
which the manufacturer of this sample gas pump has no
bearing. If necessary, perform a risk assessment of the com-
plete system this product will be installed into.
When configuring and building the complete system the rel-
evant national safety regulations for the installation site and
the generally applicable state of the art must be observed.
These can be determined through applicable harmonised
standards, among other things, e.g. IEC 60079-14. Additional
national regulations pertaining to initial operation, opera-
tion, maintenance, repairs and disposal must be observed.
When conveying flammable gasses, avoid potential exo-
thermic reactions in your system, do not use materials with a
catalytic effect in the conveyor lines. Dangerous rises in tem-
perature could result. Sample gas pump materials in contact
with media are listed in this operating manual to facilitate
the safety assessment.
Adiabatic compression is part of the physical operating prin-
ciple of bellows pumps. Dangerous rises in temperature can-
not be ruled out with improper exceeding of the operating
parameters. Conveying flammable gasses then pose an explo-
sion hazard.
Avoid these dangerous circumstances. If necessary, the com-
plete system should be secured against flashback. Follow
these notices and the applicable national regulations, prevent
malfunctions to avoid personal injury and property damage.
The operator of the system must ensure:
• The equipment is only installed by a professional familiar
with the safety requirements and risks,
• Safety notices and operating instructions are available
and observed,
• The permissible data and operating conditions are ob-
served,
• Protective devices are used and mandatory maintenance
is performed,
• Legal regulations are observed during disposal.
