ATEX IDENTIFICATION
For a pumping unit (pump, seal, coupling, motor and pump
accessories) to be certified for use in an ATEX classified
environment, the proper ATEX identification must be
present.
The ATEX tag would be secured to the pump or the
baseplate on which it is mounted. A typical tag would look
like this:
The CE and the Ex designate the ATEX compliance. The
code directly below these symbols reads as follows:
II = Group 2
2 = Category 2
G/D = Gas and Dust present
T4 = Temperature class, can be T1 to T6
(see Table 1)
