Düker is a privately owned manufacturer with a century-old background in Bavaria/Germany. In two foundries, Düker produces various types of cast iron piping material.
The Laufach works offer ductile iron fittings as per EN 545 for pressure pipelines in water supply and sewage systems. A large range of products combined with various coatings and connection systems makes Düker the top address for water suppliers and pipeline constructors with special requirements. A comprehensive range of gate and butterfly valves, tapping valves and hydrants completes the offer.
The Karlstadt factory manufactures cast iron drainage pipe systems for water evacuation from buildings as per EN 877. Cast iron sewage pipes distinguish themselves by high sound insulation and non-combustibility.
The specialty of both factories is the surface protection with high-quality enamel. Unlike standard coatings, enamel forms a compound material with cast iron and therefore represents the best corrosion protection.
Düker is the specialist in ductile iron fittings as per EN 545 with a very wide product range: numerous types of standard and special fittings, TYTON®, Novo, bolted-gland and various other socket types as well as flanges; epoxy powder coating, enamel and various other coatings as per customer requirements; and a range of nominal dimensions from DN 40 up to DN 1600. Even custom-made fittings are part of the manufacturing programme.
For the socket connections, Düker also offers various thrust-resisting joint systems such as TYTON SIT PLUS® or NOVO-SIT® for operating pressures up to 32 or even 40 bars.
In addition, Düker manufactures a range of shut-off valves such as resilient-seated gate valves, butterfly valves up to DN 1200 as well as hydrants and service connection valves.
One of the Düker specialties is the surface protection with high-quality enamel. Unlike standard coatings, enamel forms a compound material with cast iron and therefore represents the best corrosion protection.
