General legal conditions


Observance of the new directive is obligatory as of July 1, 2003.

Accordingly, machines that do not fulfill the requirements of the 94/9/EC directive may no longer be operated in potentially explosive environments.


According to the previous legislation, when a pump unit was operated in a potentially explosive environment, only the e-motor was required to comply with the applicable directive 76/117/ EWC. However, the new legislation now specifies that a system''s (such as a pump''s) mechanical element must also be constructed in accordance with the 94/9/EC directive. ALLWEILER confirms compliance by means of a declaration of conformity.


Important note:

Our pumps were already used in potentially explosive environments before appearance of the directive. Therefore, it is important to note that older units do not require "recertification." The directive applies only to devices that are recently placed into circulation, specifically on or after July 1, 2003.

Since the directive addresses both the date on which the device was placed into circulation and also the date of commissioning (start-up), it is directed at both manufacturers and importers of devices and protective systems. Secondly, however, the directive also affects system operators because they use these devices and are responsible for proper operation.
