Product description

The MTM1000 TBSS (Thrust Bulkhead Seal System) is the world’s first “all-in-one” bulkhead device that encloses a fully watertight and fireproof double mechanical seal system, a hydrodynamic bearing that supports the propulsion shaft and an automatic lubrication system and alarm management. Created to allow the reduction of on-board components, space and installation costs, the MTM1000 TBSS has derived the cartridge construction design from the industrial sector, which allows the user to receive a single product, already assembled and ready for use. The double system constituted by the MTM400 ensures resistance to shocks and vibrations. Inside, a hydrodynamic plastic bearing is positioned above a liner which has the purpose of supporting the propulsion shaft by replacing the traditional oil bearings. The TBSS is connected to a closed lubrication system in which a pump circulates the fluid contained within a barrel towards the bulkhead seal and then returns it. The system can be expanded with additional accessories such as: an air or water heat exchanger, one or more temperature sensors with 4-20mA signal, one or more pressure and flow sensors, both analog and digital. The MTM1000 TBSS is a preload and self-centering system that facilitates on-board installation and is fully customizable in size and configuration.
