The NIROSTAR ATEX is the first flexible impeller pump in the world with ATEX approval. The pump unit and electronic controls are mounted together on a sturdy trolley with large solid rubber tires (electrically 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 advantages of a high quality flexible impeller pump including dry self-priming, suitability for abrasive and corrosive liquids, 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 explosive atmosphere of gas and vapor per Gas Group IIB and Temperature Class T2 can occur.
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.

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.
Impeller Materials
The ZUWA Flexible Impeller Pumps are equipped standard with NBR (Perbunan®, Buna-N®). Five different elastomer type impellers can be equipped for ATEX applications!
