1 - GENERAL SPECIFICATIONS
The purpose of these notes is to be a reference for the safety on use, installation, maintenance, start-up and stopping of
the magnetic coupling centrifugal pumps of the TCK, TBK, TBAK series as equipment conforming to Group II, Category
2 G c T4 and Group II, Category 3 G c T4 according to the ATEX 94/9/EC Directive in force from 1 July 2003. For further
information, see Chapter 1.1 of this booklet. This feature permits the use of these pumps in ambients of potentially
explosive atmospheres classified as Zone 1 and Zone 2 according to the ATEX 1999/92/EC Directive.
P
umps
conforming to Group II, Category 1, which
means
zones classified as Zone 0 or Zone 20, cannot be supplied.
The pumps conforming to Group II, Category 2 are safe during the normal operation and in case of any foreseeable
malfunction of one of their components. A foreseeable malfunction refers to events which may cause a fault on the
pump, the leakage of liquid or other faults, which - according to the evaluation of risks carried out by POMPETRAVAINI -
may occur during the correct and conscientious use of the pump for the kind of application and in the operating
conditions specified in the Confirmation of order. For example, the use of the pump at a rotary speed being different
from the design is considered as a foreseeable malfunction.
They may not be safe in case of any malfunction considered rare or due to any wrong use by the customer, for example,
the use of a wrong liquid.
The pumps conforming to Group II, Category 3 are safe during the normal operation, i.e. when used in a correct and
conscientious mode for the kind of application and in the operating conditions specified in the Confirmation of order.
They may be not safe in case of any malfunction, even foreseeable ones.
ATTENTION!
:
The pumps series TCK, TBK, TBAK, generate a strong magnetic field:
The maximum caution and care must be taken by the possible risk personnel (
for example
carrier of
pace-maker) in charge of use and maintenance of the pumps and/or use of possible equipments that
could have a malfunction or be damaged: keep to the following minimum distances.
-
With the magnetic coupling components disassembled:
Pace-maker
carrier
=
2
metres
Floppy disk, magnetic cards, et.
= 1 metre
-
With the magnetic coupling components assembled to the pump:
Pace-maker
carrier
=
1
metres
Floppy disk, magnetic cards, et.
= 0, 5 metre
Before reading these integrative Notes, the Operator’s Manual supplied together with the pump and any documents
about the accessories or instruments supplied together with the pump must be read and carefully understood.
These notes do not replace what is shown in the Operator’s Manual, but comple
ment
it as to the safety
requirements prescribed by the ATEX 94/9/EC Directive. This Manual must be carefully preserved and kept available to
the skilled and qualified persons in charge with operation and maintenance of the pumps.

The persons involved are responsible for the operations carried out and therefore must
carefully
read this booklet and
fill in the form of chapter 9, before doing any operation. (Skilled and qualified personnel refers to those persons who - by
their experience, training and knowledge also of the respective accident prevention rules - have been authorized by the
safety manager to act for any necessary reason and are able to solve all specific problems efficiently. Also the
certification
of these persons for first aid is required).
