Our ATEX Metal Diaphragm Pump, with its simple and innovative design that allows for easy maintenance and repairs, is manufactured from either Aluminium, Cast Iron or Stainless Steel AISI 316L. Our Aluminium and Cast Iron Pumps are ATEX-rated as standard and approved for use in ATEX Zone 1. While the Stainless Steel Pumps as standard are not permitted for use in hazardous environments, special conductive TX and TZ models, featuring plastic components constructed from conductive (carbon-filled) materials, are available and ideal for use in ATEX Zones 1 and 0.
Typical applications for our ATEX Metal Diaphragm Pump:

The ATEX directive (also known as ATEX 100a) applies to products used in hazardous areas such as those subject to explosions like our ATEX Diaphragm Pumps. This directive also covers non-electrical products, like our Diaphragm Pumps. Since July 2003, it is now mandatory within the EU to have an ATEX certificate on products intended for use in EX-zones. There are three main categories (zones) in the ATEX directive:
Tapflo ATEX Metal Diaphragm Pump constructed from conductive (carbon filled) plastics HDPE or PTFE, can be supplied for use within Equipment group IIG (gas), Cat 2 (Zone 1). The conductive material ensures that no electrostatic loads will accumulate within the pump. The conductive pigments in the material reduce the surface resistance to less than 105 W. The pigments, causing the black colour do not affect the chemical resistance of the thermoplastics that the pump is made from. The ATEX Metal Diaphragm Pump has diaphragms in PTFE (with conductive back) or EPDM (conductive). An earth connection is mounted on the pump for earthing of electrostatic loads. The TX variant can be supplied across all sizes of Tapflo pumps.
Tapflo’s AOD ATEX range is now available for ATEX Zone 0 as the TZ ATEX Pump. This excludes the Aluminium Metal Diaphragm Pump series.
This pump also offers pneumatic and electric valve draining; speak to a team member to discuss this option.
