Aluminium
Stainless Steel AISI 316L
Europe’s Largest Diaphragm Pump Manufacturer
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, the special conductive TX model features plastic components constructed from conductive (carbon-filled) materials, which is available and ideal for use in ATEX Zone 1.
Typical applications for our ATEX Metal Diaphragm Pump:
| Data | Pump Size TX25 – TX820 |
|---|---|
| Max Capacity* (l/min) | 820 |
| Volume Per Stroke (ml) | 3,452 |
| Max Discharge Pressure (Bar) | 8 |
| Max Suction Lift Dry (m) | 5 |
| Max Suction Lift Wet (m) | 8 |
| Max Solids Size (ø in mm) | 14 |
| Max Temp EPDM/NBR (°C) | 80 |
| Max Temp PTFE (°C) | 110 |
Our ATEX Diaphragm Pumps are certified for use in hazardous and potentially explosive environments, complying with EU ATEX requirements for Category 2 (Zone 1) and Category 3 (Zone 2) applications.
Manufactured from conductive, carbon-filled HDPE or PTFE, these pumps prevent the build-up of electrostatic charges while maintaining excellent chemical resistance. Conductive PTFE or EPDM diaphragms and an integrated earth connection provide additional safety in explosive atmospheres.
Available across the full Tapflo pump range, the ATEX variant also offers optional pneumatic and electric valve draining for enhanced operational flexibility.
Designed with an additional set of diaphragms to reduce the risks of hazardous products being leaked into the air distribution system.
A pump station that can be mounted directly to the filter press, designed specifically for filter press feeding and straightforward pressing of slurries.
Easily inserted/removed from barrels, drums and IBCs. A mobile solution designed for emptying drums and containers, fitted with a drum tube up to 2m long.
Manufactured from Stainless Steel, offering portability and versatility for various applications within the Hygienic and Industrial sectors
A compact solution for installations with limited space, reducing discharge pressure variations and eliminating flow pulsation by up to 98%.

The pump body is manufactured from carbon-filled conductive HDPE or PTFE, which safely dissipates static electricity, making this pump certified for Equipment Group IIG (gas), Category 2, Zone 1.
This variant uses conductive-grade plastics which prevents static charge build-up, ensures compliance with ATEX zone 1 safety regulations, and includes grounding points for secure installation
Yes. Both conductive HDPE and PTFE offer broad chemical resistance, with HDPE being suited to abrasive slurries and PTFE being ideal for aggressive acids and ultra-pure media
Yes! Like all Tapflo UK Diaphragm Pumps, the ATEX Metal Diaphragm Pump can run dry without damage, and can self-prime, up to 5m from a dry suction pipe and 8m from a wetted pipe.
Connection sizes available for our ATEX Metal Diaphragm Pumps range from 1/4″ (on the TXR09 model) up to 3″ (on the T800 model), with flows ranging from 11 l/min up to 820 l/min.
Yes. For safe operation in Zone 1, you need to ensure the pump is properly grounded using designated lugs, while making use of static-safe connections and hoses.
