Integrative notes to the operating manual for magnetic coupling centrifugal pumps conforming to the ATEX 94/9/CE directive TCK... - TBK... – TBAK…
5
The pump must be used only for the applications specified in the Confirmation of order
for which POMPETRAVAINI has provided
the pump.
T
he materials used for manufacturing and
the test runs, make the pump
suitable for
the requirements. Therefore, the pump MUST
NOT be utilised for different applications. In any other case, please contact POMPETRAVAINI,
who declines any responsibility for any use different from the foreseen one, when the
respective approval has not been given.
The specifications of conformity are shown on the identification plate of the pump
(Fig. 2)
, which can be easily identified
on the pump
(Fig. 1)
and on the Service Card shown on the EC Declaration of conformity included in the central part of
the Operator’s Manual
(Fig. 3)
.
The information shown in this booklet is an integral part of it and makes fully
compliant with
the safety requirements
needed for an equipment certified according to the ATEX 94/9/EC Directive as belonging to Group II, Category 2,
or Group II, Category 3. The information therefore must be fully accepted and applied in all its parts.
The purpose of this booklet and of the Operator’s Manual is to give all information acquired by POMPETRAVAINI for a
safe and long-lasting use of their equipment. We are sure that it will satisfy the user’s need for information. If there is
any matter requiring more details, please contact POMPETRAVAINI for further explanations.

1.1 - ATEX 94/9/EC DIRECTIVE
The ATEX 94/9/EC Directive defines that all equipment intended for use in ambient of potentially explosive atmospheres
must be classified into Groups and Categories according to the safety requirements of use which this equipment is able
to achieve. The subdivision into Zones of the working ambient involved must be carried out by the user according to the
ATEX 1999/92/EC Directive. It is the user’s duty to select an equipment which ensures a safety level equal or higher
than the one prescribed for the Zone in which the pump must be used. An indication on the assignment between
Groups/Categories for the equipment and Zones of ambient is given in the following table
(Tab.1)
.
The responsibility for identifying the Zones existing in the place of utilisation of the pump and the
responsibility for the selection of the equipment having the necessary grade of protections is at the account of
the end-user.
The equipment of Group II has also been subdivided into temperature classes after a test carried out for establishing the
maximum surface temperature developed during the operation in normal conditions (ambient temperature between -
20°C and +40°C according to EN 13463-1)
(Tab. 2)
. The selection of an equipment belonging to the correct temperature
class is in relation to the ignition temperature of the gases or the dusts present in the ambient where it will be used.
