New guidelines on explosion protection have been stipulated in order to unify European standards. The guidelines have become established under the name ATEX (Atmosphères Explosible).
Directive 94/9/EC defines minimum requirements for explosion-protected devices and for the first time also includes non-electrical devices into explosion protection.
The supplementary Directive 1999/92/EC regulates the protective measures for employees working in potentially explosive atmospheres and defines the use of the device category in the different hazard zones. The zones result from the probability of a potentially explosive atmosphere developing.
seepex reacted with a number of measures designed to satisfy the requirements of Directive 94/9/EC. Depending on the conditions of use and the respective device group, zone and temperature class, a pump optimised for the customer is implemented. seepex is in a position to supply pumps from all type series in the ATEX version. In general, device groups IIG and IID with the zones 1, 21, 2 and 22 and the temperature classes T3 and T4 are offered. Other versions are tested if required. A variation for device group I is obtainable for the type series BN.
