Fluiten: Naval Mechanical seals, safety in movement

Reliability and safety are paramount in the maritime industry, where mechanical components play a vital role. Fluiten has been at the forefront of delivering innovative mechanical seals tailored to meet the unique challenges of maritime operations since 1962. Our seals are indispensable for pleasure boats, work boats and even military vessels, where stringent technical demands and harsh operating conditions prevail. Moreover, Fluiten distinguishes itself through a strong commitment to environmental responsibility. For instance, our seals are designed to be flushed directly with seawater, eliminating the requirement for auxiliary lubricants and mitigating the risk of sea contamination.

The distinctive characteristics of the maritime industry

Maritime operations pose distinct challenges that demand technically advanced solutions:

Prevention of catastrophic leaks: The integrity of the sealing component between the rotating axle shaft and the hull is critical; any failure could lead to tragic consequences.
Resistance to mechanical stresses: Seals installed on propeller shafts must withstand the axial and angular movements caused by the engine and inverter, as well as various navigation conditions.
Resistance to corrosion and abrasion: Component design and selection of construction materials must account for the corrosive marine environment, presence of sand in shallow waters, and the risk of galvanic currents.

The mechanical seals Fluiten specifically designs and tests for propeller shafts possess unique characteristics:

NO catastrophic failure: Unlike seals with elastic or plastic elements prone to rupture, Fluiten seals ensure no catastrophic failure, even under high temperature or mechanical stress, totally preventing the loss of bilge water.

High axial deviation tolerance: Fluiten seals ensure complete reliability even when there are significant axial and angular shaft deviations.

Wear-resistant sealing surfaces: the materials used resist the abrasive action of any solid particles in the water.

Corrosion resistance: Fluiten propeller shaft seals are made from stainless steel and marine bronze.

Maritime operations pose unique challenges that require technically advanced solutions:

Fluiten mechanical seals are designed to withstand harsh conditions, including high speeds, rough seas and propeller shaft displacement, ensuring optimal performance and safety in all situations:

Adaptability: Fluiten provides seals tailored for various motor-inverter units and shaft sizes, thereby catering to the diverse needs of vessels.

Stringent certification: All our products adhere to international standards and have Lloyd’s Register certification and approval.

Fluiten seals

Propeller axle seals: These seals are designed specifically for the maritime industry, and ensure utmost strength and reliability, mitigating the risk of catastrophic failure and ensuring the safety of sea travellers.
