ATEX HDPE/PTFE Diaphragm Pump

Our TX ATEX Diaphragm Pump is constructed from conductive (carbon filled) plastic, HDPE or PTFE and 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 cause the black colouring but do not affect the chemical resistance of the thermoplastics that the pump is made from.

The TX ATEX 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’s AOD Pumps.

Our TZ ATEX Pump covers ATEX Zone 0. This is available across the full Tapflo ATEX AOD range for use in continuously high-risk environments.

• 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

• Flows up to 820 l/min
• Pressures up to 160m
• Self-priming
• Solids handling up to 100mm
• Viscosity up to 200 cSt
• Can be supplied with a built-on dampener
• Solid block design, reducing the risk of leakages
• Clean-face, no-nut diaphragms
• ATEX Zones 0, 1 and 2
• Earth connection mounted onto the pump, ensuring the earthing of electrostatic loads
• ATEX-variant can be supplied across all AODD pump sizes

The TK Series Pulsation Dampeners are designed for seamless integration with all our Plastic and Aluminium Air Operated Diaphragm Pumps.

• Available for all Tapflo plastic AODD Pumps and their ATEX-rated variants
• Available for all Tapflo Aluminium AODD Pumps
• As the dampener block is constructed from solid aluminium, the TK series for Aluminium Diaphragm Pumps is ATEX-rated as standard
