For us, this trade fair is the most important platform to present our low-maintenance and highly reliable sealing systems to the decision-makers of the world’s largest fleet.
Greek shipowners control a vast share of strategically important vessels:

These ocean-going vessels require technology you can rely on. Our axial shaft seals and rudder stock seals from ProfiSeal have been developed specifically for these extreme demands. Whether for new builds or fleet modernization – we provide solutions that minimize downtime and increase operational safety.
