NOTICE
Restriction for ATEX pumps
The P2.x Atex pumps can pump non-flammable gaseous me-
dia and flammable gaseous media that could occasionally be
explosive in normal operation (Sampling zone 1). Sampling
gas from zone 1 is generally forbidden if the gas flow leads to
a dangerous electro-static charge in the bellow / pump body
(also see the "Operation" section).
The Atex versions are suitable for use in Equipment Group II,
Equipment Category 2G, Explosion Group IIC, Temperature
Classes T3 and T3/T4 and must not be used in dusty areas.
When installed outdoors, ensure adequate protection from
the weather, see chapter Requirements to the installation site
[} 10].
2 Safety regulations
This product has no dangerous ignition sources when ob-
serving regulations and operating parameters in these oper-
ating instructions. Installation into a complete system can
pose new hazards the manufacturer of this sample gas pump
has no control over. If necessary, perform a risk assessment of
the complete system this product will be installed into.
Observe the relevant national safety regulations for the in-
stallation site and the generally applicable state of the art
when configuring and building the complete system. These
can be determined through applicable harmonised standards,
e.g. EN 60079-14 among others. Additional national regula-
tions pertaining to initial operation, operation, maintenance,
repairs, and disposal must be observed.
Avoid any exothermic reactions in your system, do not use
materials with a catalytic effect in the conveyor lines. Danger-
ous rises in temperature may otherwise occur. Sample gas
pump materials in contact with mediums are specified 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 when exceeding the operating parameters.
Avoid these dangerous conditions. If necessary, protect the en-
tire system against flashback. Follow these notes and the ap-
plicable national regulations and prevent malfunctions to
avoid personal injury and property damage.
The operator of the system must ensure:
• The equipment is installed by a professional familiar with
the safety requirements and risks,
• Safety notes and operating instructions are available and
observed,
• The permissible data and operating conditions are ob-
served,
• Protective devices are used and the required maintenance
is performed,
• The unit is disposed according to the law.
