ATEX INFORMATION

CAREFULLY READ THE INSTRUCTIONS AND WARNINGS BEFORE STARTING TO OPERATE THE EQUIPMENT
This pump can be operated in potentially explosive atmospheres (ATEX).
Directive 2014/34/EU of the European parliament establishes essential
health and safety requirements for the use of devices and protective
systems in these atmospheres and allows the technical expression of the
requirements contained therein to fall within the harmonized European
norms. Samoa Industrial S.A has followed a procedure whereby it
demonstrates the conformity of the product that accompanies this
manual with these requirements. This process has consisted of the
preparation and subsequent deposit of the required technical
ATEX MARKING
In the pump that accompanies this manual you should locate a label
with the following information included (do not use it in ATEX if you do
not incorporate it):
Directive part
2014/34/EU
Ex: indicates that it is possible to use this pump in a potentially explosive
atmosphere.
h: indicates that it refers to the standard 80079-36.
IIB/IIIB: indicates the group of the equipment, in this case destined to
be used in explosive atmospheres of gas, except mines or when the
typical gas is hydrogen (in the directive, cat. 2G zone 1); and in dusty
atmospheres, except mines or with conductive dust (in the directive, cat.
2D zone 21).
T6...T5: indicates the temperature class for group II. In this case, the
class is variable from T6 (<= 85ºC) to T5 (<= 100ºC) because the
maximum surface Tª of the pump will depend on that of the grease to
be pumped, which by technical specifications is fixed at 70ºC maximum,
and the maximum heating by friction of the pump (+ 25ºC).
T70ºC...T95ºC: indicates the maximum surface temperature of the
pump for group III. In this case, it is variable from 70ºC to 95ºC because
it will depend on the T of the grease to be pumped, which by technical
specifications is set at 70ºC maximum, and the maximum friction
heating of the pump (+ 25ºC).
ZONES OF USE OF ATEX PUMPS
Zones defined by group II (gas) and III (dust): suitable for zones 1, 21, 2
and 22.
•
Zones 1 and 21: areas in which explosive atmospheres caused by
mixtures of air and gases, vapours, mists or air/dust mixtures are
likely to occur.

Standard part
UNE-EN ISO 80079-36:2017
documentation in the notified body mentioned in the declaration of
conformity together with an internal control of the production.
The devices intended for use in this type of atmosphere must have a
specific marking that is an essential tool for the end user for the correct
location and use of the pump. Next, the content of the marking
incorporated by these pumps suitable for ATEX will be explained.
Remember that you should never use a pump that is not marked with
this label in potentially explosive atmospheres.
Gb/Db: indicates the EPL of the pump.
In addition, the marking includes the reference number of the technical
documentation that has been deposited with the notified body (see
declaration of conformity), followed by the letter "X".
X: indicates that there are special conditions of safe use that are
transmitted through this instruction manual to the end user, which in
this case are:
•
Ambient temperature for which the pump is intended:
-10ºC≤Tamb≤50ºC
•
Maximum surface temperature of the pump is dependent on the
temperature of the grease to be pumped, which should never
exceed 70ºC, or the ambient one (whichever is greater).
•
A grounding cable with a clamp is included, which must be placed
firmly and stably and protected on a conductive element of the
installation, foreign to the pump and connected to the ground.
•
Zones 2 and 22: areas in which explosive atmospheres caused by
mixtures of air and gases, vapours, mists or air/dust mixtures are
unlikely to occur and if they do occur, do so infrequently and for a
short period of time only.
