The evacuation of suction pipes and centrifugal pumps in Ex-areas in accordance to the ATEX guidelines is possible. By using our new compressed air ejector type EL35-55-ExA nearly all gases and liquids can be evacuated. In tank stations or other Ex-areas either pressure controlled or level controlled fully automatic priming systems can be used. All different types of our ejectors are available with such an ATEX certificate. There are only a few slightly changes of the design necessary. Inside Zone 0, outside Zone 1 is permitted.
