10.11 ATEX characteristics of the pumping installation
A pumping installation can be composed of materials (motor, reducer, sensors…) from which ATEX characteristics are different
from those of the pump.
In this case, the group will have ATEX characteristics corresponding to characteristics ATEX of the component with the lowest
level of protection.
10.12 Pumping vat of retention
At a constant arrival of liquid in a vat of retention in an ATEX zone, the uninterrupted start-up can generate a classification in zone 0.
The case can only arise when the pump is used in the starting position. It is then imperative that the suction pipe always has liquid
present so as not to create explosive conditions in the presence of fuel and combustive agents. Thus, the adjustment of the low
point of the tank will have to be higher than the opening of the suction pipe.
That will always result in the presence of liquid and not of gas and liquid.
10.13 Marking of the pump
The marking of the Albin pumps is of type:
Albin .............................................
TYPE ALH… or ALHS…...............
II 2 G T4 or II 3 G T4.........
N° series………………..................
Year………………..………………..
The marking of the Albin groups is of type:
Albin………………..……………….
Group ALH or ALHS....................
II 2 G T4 or II 3 G T4.........
N° series………………..................
Year………………..………………..
In the case of a pumping group, ATEX certified materials will retain their original markings.
