PFEA vane and PVPCA piston pumps are certified for application in potentially explosive atmospheres according to ATEX 94/9/CE, protection mode Ex II 2/2 GD cbk IIC T6/T5/T4 (group II for surface plants with gas, vapours and dust environment, category 2, zone 1, 2, 21 and 22).

The external surface temperature of the pump is in accordance with the certified class, to avoid the self ignition of the explosive mixture present in the environment.
