Quality standards and directives
The ATEX directive (also known as ATEX 100a) is applicable on products used in explosion hazardous zones. This directive also covers non electrical products, like our diaphragm pumps. From July 2003, it is mandatory within the EU to have 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
We are proud to introduce our product range, adapted to conform with the directive. Our ATEX certified pumps have the code TX... and the pulsation dampeners PDX...
The following models are now certified for Equipment group IIG (gas):
| Pump model | ATEX category |
| Conductive PE & PTFE pumps | CAT 2 |
| Cast iron pumps | CAT 2 |
| Stainless steel pumps with conductive centre unit | CAT 2 |
| Aluminium pumps | CAT 2 |
| Corresponding pulsation dampeners | CAT 2 |
The Tapflo manufacture process is certified according to ISO 9001:2000.
All pumps and pulsation dampeners are CE marked and fulfill the demands of the EC machinery directive 89/393/EEC with amendments.
