ROV THRUSTERS

BY SUBMARINE ENGINEERING

We have been involved in the design and construction of underwater systems for forty years. Over the past twenty years, we have developed a new range of underwater electric thrusters and motors.

Our thrusters/motors can be used on the following underwater systems.

  • ROV
  • WCROV
  • AUV
  • SUBMARINES
  • EXCAVATION TRHUSTERS
  • MOTOR FOR SUMMERSIBLE PUMPS
  • SPECIAL MOTORS ON CUSTOMER REQUEST

Some salient features of the construction of

our thrusters

100% safety under pressure. No mechanical seal or gasket is present on the propeller shaft. The traction of the propeller shaft, takes place with a permanent magnet joint. Maintenance is reduced by 90% (compared to a mechanical shaft seal)

For standard depths, no oil pressure compensator is present. It is not necessary to check the dielectric oil level, before and after each dive.

The use of full ceramic bearings, ensures a long operating life on the  rotating parts exposed to water.

Operation depth standard: -900 -1500. Optional - 3000 mt.

100% compatible with all thrusters of the same category.
