The pumps satisfy a new EU directive 94/9/EC (ATEX 100a) which is now also mandatory for non-electrical equipment. The diaphragm pumps are operated by compressed air and are produced from conductive plastic material or metal. By using compressed air instead of electricity, the potential to be a source of ignition is eliminated.
The new range is produced from conductive plastic material or metal and can be used for the transport of solvents, alcohols and chemicals which can form explosive gas compounds.
The diaphragm pumps can handle most types of liquids, and can function by direct running which is recommended in the case of viscous liquids or self-priming or submerged in the liquid, according to Tapflo.
The new EU directive means that all equipment covered by the new directive must be updated with ATEX-certified equipment no later than 1 July 2006. Workplaces brought into operation on 30 June 2003 or later must be equipped with ATEX-certified equipment from start of operation.
Börje Johansson, managing director of Tapflo, said: "We can see in this area major and important potential for sales of our diaphragm pumps in harsh working environments."
