Conditions of use for FLUDEX couplings in potentially explosive areas
The coupling with fusible safety plug with indication
is suited for the service conditions specified in
Directive 2014/34/EU:
•
Equipment group II (use above ground) temperature class T3 of category 2 and 3 for areas where there
are explosible gas, vapour, mist, air mixtures as well as for areas where dust can form explosible
atmospheres.
•
Equipment group I (underground applications) of the category M2
If it is to be used below ground in potentially explosive areas, the coupling, which is
made of aluminium, must be provided with a robust casing to preclude the risk of
ignition from e.g. friction, impact or friction sparks.
The depositing of heavy metal oxides (rust) on the coupling housing must be
precluded by the casing or other suitable precautions.
The FLUDEX coupling can be delivered with attached brake disk or Vbelt pulley.
The supplier of the subassembly is responsible for the construction of the belt drive
or brake disk in conformity to the guidelines. To be noted are, amongst other things,
hazards from electrostatic charging and hot surfaces.
The use of Vbelts in conjunction with IIC gases is not permitted.
