General information

Pumps bearing an ATEX label and accompanied by a declaration of conformity in
accordance with 2014/34/EU are designated for use in potentially explosive areas.
They belong to equipment group II, equipment category 2G, explosion group IIB,
safety by design.
With the -FS option (flame arrestor at the outlet of the bleed chamber), a poten-
tially explosive atmosphere is also permitted in the bleed chamber. It corre-
sponds to equipment group II, equipment category 2G, explosion group IIB,
flame-proof enclosure.
Potentially explosive atmospheres are not permitted in the drive unit and high
pressure unit.
Refer to the figure 10-2 "Diagram of ATEX zones" for the permissible zones.
The designation is indicated on the rating plate and on the general drawing.
