Thrusters

Some significant particularities of our thrusters.

  • 100% Security.
  • 90% Reduction on Maintenance.
  • Operation Depth – 1500-3000 mt. (option 6000mt.)
  • Electromagnetic Compatibility Directive 89/336/EEC

No mechanical seal or gasket is present on the propeller axis. The traction of the propeller axis, takes place with a high efficiency permanent magnet coupling.

  • 100% safety to water penetration.
  • Maintenance is reduced by 90%. (compared to mechanical seals)

Absence of the pressure compensator.

  • No oil expansion problem, due to high temperature.
  • No oil leakage.
  • No adjustment or checking of the oil level, must be performed.
  • Reduced timing of pre dive and post dive check.
  • Zero maintenance. (compared to compensator systems)

The use of fully ceramic bearings, guarantee a long working life on rotating parts exposed to water.

Our thrusters, are interchangeable with most of the thrusters on the world market. (example but not limiting: Seaeye-Subatlantic-Technadyne)
