What is ATEX?
Obligation of Safe Equipment in Explosive Atmosphere
The ATEX (ATmosphères EXplosibles) directive is an EU directive (2014/34/EU) for equipment and protection systems used in areas containing explosive atmospheres. The use of ATEX-approved equipment is mandatory in environments where explosive gases or dust may be present, such as chemical, petrochemical, paint, solvent and grain plants.
Since air diaphragm pumps do not use electric motors, they eliminate the risk of basic electrical ignition. However, antistatic material and grounding connection is mandatory for the risk of static electricity discharge.
- Zone 0/1/2 (gas) and Zone 20/21/22 (dust) classification
- AODD pump: no electricity = no risk of electrical ignition
- Antistatic housing and ground wire requirement
- Pumpport PA series models with ATEX certification
- CE marking + ATEX certification = directive compliance
Zone Classes
ATEX Zone Classification
Zone 1 / Zone 21
In normal operation an explosive atmosphere is occasionally generated. Category 2 equipment (AODD typical area of use).
Zone 2 / Zone 22
Rare explosive atmosphere in abnormal conditions. Category 3 or 2 equipment may be used.
Certification
The Ex certificate and CE marking issued by the notified body prove compliance with the directive.

Questions
-
No, absolutely not allowed. Only Category 2 or Category 1 approved ATEX equipment may be used in Zone 1 areas. The use of inappropriate equipment carries serious legal and safety sanctions.
-
No, it does not. Not requiring electricity does not imply ATEX compliance. Antistatic material to prevent the build-up of static electricity, an earthing connection and an official ATEX certificate are required.
