Achilles JQS

CYLINDER PROVIDER WITH A GLOBAL REACH

NURMI CYLINDERS OYMARINE AND OFFSHORE

Nurmi has delivered seaworthy hydraulic cylinders for the marine environment for over 30 years. We provide global marine sector customers with tailor-made solutions based on our own cylinder engineering expertise and best quality materials globally available. Nurmi special cylinders are designed for demanding offshore and underwater applications in extreme temperatures as well as humid and acidic environments. We employ the most advanced painting and coating techniques to ensure superior corrosion resistance and cylinder performance in the often unforgiving marine environment.

Our range of sensor-outfitted cylinders includes marine, offshore, dam and linkspan cylinders. In marine applica-tions, acid proof cylinders are also used in underwater solutions. These cylinders work underwater with no risk of paint delamination or lifting.

Nurmi cylinders brave the waves

The meticulous documentation of all cylinder design and manufacturing phases gives our customers assurance of quality and reliability. In addition to continuous R&D, we are also a forerunner in applying 3D to cylinder engineering.
