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 documentation in the notified body mentioned in the
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: 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).
T4: indicates the temperature class for group II. In this case, the class is
T4 (<= 135ºC), which takes into account the maximun temperature
that pump´s surface could reach when oil's one is 70ºC (maximum
allowable value stated by this manual) and several hours of dry running
overheating occurs.
ZONES OF USE OF ATEX PUMPS
Zones defined by group II (gas): suitable for zone 1.
•
Zone 1: areas in which explosive atmospheres caused by mixtures
of air and gases, vapours or mists are likely to occur in
normal operation.

Standard part
UNE-EN ISO 80079-36:2017
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: 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:
-20ºC≤Tamb≤50ºC
•
Maximum surface temperature of the pump is dependent on the
temperature of the oil 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.
