1 Introduction
1.1 Intended use
Sample gas pumps are intended for installation in gas analysis 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 explos-
ive 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 temperature and the pump’s temperature class. Flammable mediums 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 informa-
tion on specific intended use, existing material combinations, as well as pressure and temperature limits in the data sheets.
When installed outdoors, ensure adequate protection from the weather, see chapter Requirements for the set-up location [>
