WHAT ARE TX EXPLOSION PROOF PUMPS
The ATEX directive (also known as ATEX 100a) is applicable on products used in hazardous areas such as those subject to explosions like our TX Explosion Proof 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 which are intended for use in EX-zones.
There are three main categories (zones) in the ATEX directive:
- CAT 1 (zone 0), flammable material present continuously or for long periods
- CAT 2 (zone 1), flammable material present occasionally in normal operation
- CAT 3 (zone 2), flammable material present in abnormal conditions for short periods
Tapflo TX Explosion Proof Metal Pump constructed from conductive (carbon filled) plastics PE 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 TX Explosion Proof Metal 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.
