ATEX Pumps & Motors

Flux manufactures a range of drum and barrel pumps for use in ATEX zoned areas (to ATEX Directive 2014/34/EU). These products are notified by the red Ex symbol.  Detailed information can be found by clicking the product tabs below.

All Flux ATEX pumps are constructed from 316 Stainless Steel, with conductive ETFE impellers (or PTFE stator in the case of the 550 GSX). Pumps for low viscosity applications include the FP424, F430S and F425 Series. F430S FOOD is also approved for sanitary use (EC 1935/2004 standard) and is particularly well suited to pumping alcohols. The F550 GSX Series is designed for use with high viscosity fluids (max viscosity 30,000 cP). ATEX certified drive motors include electric commutator motor F460, brushless motor FBM 4000 and compressed air motors F416 and FPM.

The ATEX Directive 2014/34/EU

The ATEX Directive requires equipment intended for use in explosive atmospheres to be designed and manufactured to minimize the occurrence and severity of accidental explosions. It applies to new equipment intended for use in explosive atmospheres such as electrical components and machinery.

An ‘explosive atmosphere’ is a mixture of flammable substances (gases, vapours, mists or dusts) with air, under atmospheric conditions capable of causing a hazardous explosion if ignited. ‘Equipment’ is equipment capable of igniting the explosive atmosphere under normal or fault conditions (in this case the pump and motor, which are placed into the explosive atmosphere).

Standard 2014/34/EU defines technical measures for assessment and reduction of explosion risks. Articles and other annexes within the Standard define the certification procedures that manufacturers have to apply. Equipment that complies with the ATEX Directive can bear the CE and red Ex markings. Further markings form a code defining the suitability of the equipment for different types of explosive atmospheres.
