Drinking Water

For more than 30 years AVK GUMMI has manufactured components for use in drinking water supplies. Our experience in this field derives from many years of close co-operation with leading manufacturers of fittings, valves and pumps. The R&D department of AVK GUMMI uses this knowledge to develop rubber compounds with continuously improved properties.

    


The following factors are of decisive importance for a rubber sealing when used in connection with drinking water: 

  • Fulfilment of approvals and regulations 
  • Minimum permanent deformation, which ensures leaktight gaskets
  • Resistance to chemical processes used for water treatment, such as ozonation, chlorination and chloramination
  • Taste and smell neutrality
  • Change of volume of rubber in water
  • Wear resistance, friction etc.

 

                          

AVK GUMMI also serves other water related industries such as

  • District heating
  • Sewage
  • Waste water treatment

AVK GUMMI co-operates with leading manufacturers of valves and fittings for district heating supplies. Here, there are different demands, but especially reliable sealings, optimum function, a long lifetime and temperature resistance are important factors. Resistance to inhibitors and friction lowering chemicals that are added to district heating water is needed.
