CE Marking & PED 97/23/EC

For selling to and within EU countries, it has become increasingly important to have CE certification and marking. For our industry of metering pump accessories, Pressure Equipment Directive (PED) 97/23/EC is applicable.

The majority of our products are classified as SEP (Sound Engineering Practice). This classification means that our products do not require CE marking or certification in order to be used within the EU.
