2.7 Safety information for ATEX designs
This chapter lists all safety information for ATEX designs. Safety informa‐
tion is listed again at the relevant points in these operating instructions.
This safety information is supplementary to or replaces the safety informa‐
tion for non-ATEX designs. If the safety information for ATEX designs con‐
tradicts the other safety information, then the safety information in this
chapter applies to ATEX designs.
2.7.1 Intended use
n
Only operate an ATEX design of pump in premises at risk from explo‐
sion in accordance with the applicable guidelines.
n
Pumps with the identity code option "Multi-layer safety diaphragm with
rupture signalling (contact)" are only approved for use with flammable
feed chemicals with electrically conductive dosing heads, at back
pressures of over 2 bar and only if the operator takes appropriate
safety measures. Rupture signalling must switch off the pump immedi‐
ately.
n
Do not expose the ATEX design to any sources of ionising radiation or
electromagnetic high frequency radiation in the range 10
4
... 3x10
15
Hz
or laser radiation or ultrasound or lightning without putting in place
measures in line with EN 80079-38.
n
Do not allow the ATEX design to meter media, which tends to produce
exothermic reactions or self-ignite (examples of exothermic reactions:
pyrophoric substances with air, alkali metal with water, decomposition
of organic peroxides, polymerisation reactions), without taking effec‐
tive measures in accordance with EN 80079-38.
