SECO GmbH is Germany's largest, independently working manufacturer of pistons and cylinder liners for 4-stroke diesel engines with diameters ranging up to 500 mm.
Our products are used in stationary operated power generating engines in more than 40 countries worldwide. The shipping sector is appreciating the quality and reliability of our goods by using them in main and auxiliary engines.

Founded over 140 years ago and traditionally committed to our customers' quality requirements, SECO has been manufacturing its products at its new premises since 2011.

Here, in the geographical center of Germany, close to the Harz Mountains and the UNESCO World Cultural Heritage town of Quedlinburg, SECO has established a modern facility.

So, for all our existing and future customers, there are at least two good reasons for visiting our site!
