For safe and efficient handling of fluids in chemical and pharmaceutical applications Since 2003 it has been mandatory for all new equipment used in explosive atmospheres to comply with the EU directive 94/9/EC otherwise known as the ATEX Directive.

Traditionally Acetal was the only groundable plastic that was commercially viable. This did not provide the range of applications and uses of the more common Polypropylene models, but with the latter being an insulator rather than a conductor, polypropylene was not safe for use in hazardous areas.

These new models provide the safety of groundable Acetal with the chemical compatibility of Polypropylene. This new material will safely prevent the pumps electro-static build-up by conducting away any charge through a groundable earthing connection. This controlled feature makes the transfer and supply of potentially flammable products such as solvents, inks, lacquers and a wide range of chemicals, safe from the hazards of static sparking.

Tests have been carried out by a Notified Body to determine the suitability of the material. These test showed the conductivity to be well in excess of the stated requirements, these included surface resistance tests and also mechanical strength tests conducted at both minimum and maximum temperatures of use for the material.

Available in groundable versions of the three main polypropylene models, B15, B25 & B50.
