  • Made of seawater resistant bronze, all shaft and bearing surfaces are CNC machined to 2/1000mm accuracy
  • Its hydrodynamic shape ensures low water resistance and thus less cavitation
  • Heavy-duty seal designed for separation of two media, combining excellent contamination protection and supreme sealing performance
  • Crucial vibration damping capacity of the seal which reduces harmful propeller-generated vibrations
  • Easy to replace anti-electrolysis aluminium anode
  • Hardened spiro-conical gears, developed for us by leading German manufacturers. The precise elemental geometry leads to a quieter running of the gear sets and longer lifetime
  • As a result of considerable development work and numerous tests, we invented and now produce our unique skewback six-blade propeller. It is made of DuPont™ Delrin® acetal resin, a highly versatile engineering polymer
  • Our skewback six-blade propellers generate less cavitation, which, in addition to the carefully chosen hydroacoustic design, results in great noise reductions
  • With blade tips swept back against the direction of rotation, while bending rearward in reference to the longitudinal axis, our propellers generate “ahead” thrust which almost coincides with “reverse” thrust, i.e. the thruster system is reliable for maneuvering in both directions
