Figure 1 shows the VP, VPK, VPB, series of ATEX progressive
metering devices with their inlet volumetric flow data.
3.2 ATEX marking according to Directive
2014/34/EU (ATEX)
The ignition hazard analysis conducted in
accordance with EN 80079-36 / -37 found
that SKF basic metering devices of series VP,
VPK, and VPB without electrical attachments
do not constitute own potential sources of
ignition. They consequently do not fall under
the scope of Directive 2014/34/EU and thus
do not bear explosion protection marking.
To better incorporate the basic metering de-
vices into the operator's explosion protection
concept, these metering devices have also
been equipped with an equipotential bond-
ing terminal and added to this manual as
ATEX metering devices.
The combination of the metering devices
described here with the explosion-proof
electrical components specified in this
manual does not create an additional source
of ignition. The explosion protecting marking
on these metering devices is based solely
on the attached explosion-proof electrical
component(s).
