DUAP- Quality is based on History

The history of DUAP is a story of continuity on the one hand and flexibility on the other. Since its establishment in 1943 DUAP has manufactured injection nozzles. The first customer was the leading tractor manufacturer in Switzerland.

Since 1963 DUAP have made co-operation agreements with some of the most important engine builders, for example Sulzer brothers, S.E.M.T. Pielstick and Wärtsilä for whom DUAP has developed and produced modern injection systems for their engines.

During this time injection systems for Diesel engines of all power ranges have been delivered throughout the world covering the complete scope of applications, Marine, Traction, Stationary, Automotive, and Aeronautical. Based on its extensive experience DUAP is pushing forward with its own research and development into new areas of material processing.

It is important for our customers to know what sort of a company we are and how we approach our responsibilities in business.

Man stands at the centre of our philosophy. To identify correctly his wishes and complex problems and to offer solutions for these, is in the interests of both parties. We have to listen! «Give and Take» is an intrinsic part of all partnerships and from this stems the AVSP (added value sharing partnership) Philosophy.
