ATEX rating is a crucial certification that ensures safety in environments containing flammable materials. In this blog, we’ll explore the fundamentals of ATEX rating, its zones, and the ATEX-rated pumps offered by Tapflo UK. Discover the significance, types and advantages of ATEX-certified Industrial Pumps.
What is ATEX
ATEX, which is an abbreviation for ‘Explosive Atmospheres,’ is a certification mandated by law to enhance safety in environments prone to explosive conditions. These environments commonly contain a mixture of gas, vapour and dust which can ignite in certain conditions. This certification encompasses both electrical and mechanical products, categorised based on their risk assessment results.
These electrical and mechanical products are split under the ATEX Directive. Electrical products are required to undergo tests as part of their ATEX certification, whereas non-electrical products can be self-certified.
ATEX Zones
Understanding ATEX zones is vital for selecting the appropriate equipment.
- ATEX Zone 0: Presence of flammable material for extended periods
- ATEX Zone 1: Flammable material likely during normal operation
- ATEX Zone 2: Unlikely presence during normal operation, if it occurs, for a short time
The zone number is followed by G (Gas) and/or D (Dust), indicating the type of explosive material.
Explosive Material Classification
ATEX classifies explosive materials into groups (I, II, III) and assigns a letter for the substance. Temperature classes like T4 or T135° are determined through assessments.
Equipment Level Protection (EPL)
EPL denotes the product’s suitability for specific atmospheres, categorised as:
- EPL_c: Basic requirement for normal operation
- EPL_b: Fine under normal operation, expecting standard malfunctions
- EPL_a: Necessary for high-risk atmospheres, considering various failures
Why ATEX Certification Applies to the Industrial Pump Industry
ATEX certification of a product is required within the Industrial Pump Industry when the product is used in a potentially explosive environment. It is mandatory for products sold in the EU to undergo ATEX certification when used in these conditions. Hazardous areas, such as chemical processing and the paint and varnish industry, are likely to utilise an industrial pump in their factories and will, therefore, need an ATEX-rated pump as there is likely to be a mixture of flammable materials in the atmosphere of these factories.
ATEX Pumps Supplied by Tapflo UK
TX ATEX Diaphragm Pumps
The centre section of our ATEX rated Diaphragm Pump is fitted with carbon-filled Polypropylene, Aluminium or Cast Iron depending on the application/material required. The carbon-filled centre sections are a different colour due to conductive pigments inside the material, which reduces the surface resistance of the pump and ensures that electrostatic doesn’t build up inside the pump.
Our TX range of Diaphragm Pumps and our Guardian System is both ATEX rated to Zone 2. It is crucial that all products within a system hold the same ATEX certification to ensure the environment can be classified as ATEX. Our Diaphragm Pumps are available in Metal, HDPE and PTFE materials and we also offer our Sanitary and Aseptic Diaphragm Pumps as ATEX rated.
Tapflo now also manufacture a Diaphragm Pump suitable for ATEX Zone 0. The TZ Pump is available across the full Tapflo Diaphragm Pump range, ask the team about this pump using our live chat or call Tapflo UK HQ.

ATEX-Rated Centrifugal Pumps
We have several ranges of Centrifugal Pumps that carry ATEX certification:
- Industrial Centrifugal Pump (CTI)
- Hygienic Centrifugal Pump (CTH)
- Industrial Self-Priming Centrifugal Pump (CTS-I)
- Hygienic Self-Priming Centrifugal Pump (CTS-H)
Tapflo also supplies Salvatore Robuschi Pumps and a Pomac Sanitary Self-Priming Centrifugal Pump which can also be provided with an ATEX rating.
Additional ATEX-Rated Pumps
Verification of ATEX Certification
Proving your pump’s ATEX certification is crucial. Request the ATEX certificate from Tapflo’s Sales Team, ensuring the visible ATEX rating on the pump matches operating conditions. Additionally, all products, including our ATEX Pumps and Guardian System, have to have the ATEX rating visible on the pump. This allows users to see the conditions and protection level applicable to the product.
This visible protection level will also include operating conditions such as the ambient temperature or the medium surface temperature. The protection level will also state the conditions of the atmosphere, for example, whether the flammable material is gas or dust.
