Düker GmbH

Portrait of Düker

Düker GmbH is a medium-sized company with a tradition of a smeltery and hammer mill. Today there are three divisions: fittings and valves, drainage technology and jobbing foundry. The former division glasslining technology has spun off to a separate company, the Düker Email Technologie GmbH.


With cast iron products, Düker is one of the leading manufacturers of valves and pressure fittings for the drinking water and gas supply as well as of pipes and fittings for the drainage systems.



In the Lower Franconian locations Karlstadt and Laufach there are around

500 employees with an apprenticeship rate of approximately 8%. So Düker is one of the biggest German iron foundries.
