The pump unit and electronic con- trols are mounted together on a sturdy trolley with large solid rubber tires (elec- trically conductive). The trolley includes a height-adjustable telescopic handle to ensure easy mobility in and around the worksite. Due to the compact design of the NIROSTAR ATEX, it is transportable in most passenger cars. The NIROSTAR ATEX brings all the ad- vantages of a high quality flexible im- peller pump including dry self-priming, suitability for abrasive and corrosive li- quids, and pulsation-free flow. This flexible impeller pump meets the strict requirements of Category 2G of Directive 2014/34/EU. It is designed to convey flammable liquids per Gas Group IIB and Temperature class T2. The unit can be used in areas where an explosi- ve atmosphere of gas and vapor per Gas Group IIB and Temperature Class T2 can occur. 05/2024 WHAT IS ATEX? ATEX is an abbreviation for „ATmosphere EXplosible“. At the same time, ATEX is the abbreviated name of the European Directive 2014/34/EU concerning the placing on the market of explosion-proof electrical and mechanical equipment, components and protective systems. It came into effect on 1 July 2003, and all new equipment and protective systems have been subject to it since. APPROVAL FOR USE IN POTENTIALLY EXPLOSIVE ATMOSPHERES The ATEX-NIROSTAR series has a type examination by a notified body in accordance with Annex III of Directive 2014/34/ EU, including the essential health and safety requirements in accordance with Annex II of Directive 2014/34/EU as a category 2 non-electrical device.
