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

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)
