Düker GmbH

Ductile Cast Iron Hydrants

Hydrants are an important part of the public water supply system, with a wide area of application, such as:

  • drawing water for fire fighting and emergency conditions
  • setting up of temporary network connections in case of an emergency
  • aeration and venting of pipe sections
  • temporary water supply during events or on construction sites

All Düker hydrants are made of ductile cast iron - a material with outstanding properties, such as a long service life, leak tightness, good corrosion resistance, cost effectiveness and full recyclability.


The Düker hydrants are reliable and ideally suited to meet the requirements of their application fields. 


In order to ensure even better and permanent protection against corrosion and encrustation, our hydrants are fully enamelled, according to the requirements of the DEV guidelines and EN ISO 11177.
