Product description

Mictrotem’s MTM1000 TBSS (Thrust Bulkhead Seal System) stands as a groundbreaking innovation, being the world’s first comprehensive bulkhead device integrating a fully watertight and fireproof double mechanical seal system. Moreover, MT1000 TBSS is a hydrodynamic bearing supporting the propulsion shaft, and an automatic lubrication system with alarm management. The term “Thrust Bulkhead Seal System” (TBSS) refers to the bulkhead device used in marine engineering and propulsion systems, designed to provide a seal at the point where the propulsion shaft penetrates the bulkhead of a vessel.

Crafted by Microtem with the scope of reducing onboard components, optimize space requirements, and installation costs, the MTM1000 TBSS adopts a cartridge construction design inspired by the industrial sector, providing users with a single pre-assembled product ready for immediate use.

The double seal system, featuring Microtem’s MTM400 propeller shaft seal, ensures exceptional resistance to shocks and vibrations. Within MTM1000 TBSS, a hydrodynamic plastic bearing is situated above a liner, serving to support the propulsion shaft while replacing traditional oil bearings. The Thrust Bulkhead Seal System of the MTM1000 is seamlessly connected to a closed lubrication system, wherein a pump circulates the fluid contained within a barrel towards the bulkhead seal before returning it. Also, the system provided by MTM1000 TBSS can be further enhanced with additional accessories, including an air or water heat exchanger, one or more temperature sensors with 4-20mA signal output, as well as pressure and flow sensors, available in both analog and digital formats. Offering a preload and self-centering system, MTM1000 TBSS facilitates onboard installation and is fully customizable in terms of size and configuration, ensuring compatibility with diverse vessel requirements and specifications.
