Pistons for power plant- and marine diesel engines

The development and production of pistons for 4-stroke engines, up to 500 mm in diameter, has a long-standing tradition in our company.

Already since the 1960s, SECO accompanied several engine manufacturers with the development of new piston design for continuously increasing engine outputs.
Today, we are able to produce more than 120 different pistons for various engine types and brands. To extend the lifetime of e.g. our piston crowns significantly and, as a consequence, to reduce our customer´s operating costs considerably, we have developed innovative technologies. Nowadays, over 80% of our pistons or piston crowns are supplied in our WearResist® -quality to our customers. In addition we supply piston crowns with a HOCOREL®-coating to prevent hot- or even high-temperature corrosion at engine operation under full load and unfavorable boundry conditions.

Even though the designs and versions of pistons manufactured by SECO are manifold -they all have one thing in common: Prior to shipment, each single piston will be inspected by 100% in regard to the material properties and dimensions.
