Product description

The MTM907 propeller shaft seal is engineered to revolutionize the market for medium to large boats, offering unparalleled value for money in its category globally. With its innovative design, MTM907 stands as the world’s most dynamic compact safety barrier split shaft seal, setting new standards for efficiency and safety.

The MTM907 propeller seal features a dynamic compact safety barrier design, ensuring optimal safety without compromising on space efficiency.  The stationary flange, made from premium 316 Stainless Steel, is customizable to accommodate up to 6 radial holes (optional) for additional functionalities such as flushing, temperature sensing, vibration monitoring (triaxial), pressure sensing, or vent line integration. Flange specifications including size, number, spacing, and pitch center distance can be tailored to meet specific requirements. As fot the stationary ring of MTM907, it is available in Silicon Carbide (S1) or Tungsten Carbide (T1), inserted in a 316 stainless steel case, ensuring durability and reliability in diverse operating conditions.

The rotating case provided in 316 stainless steel with insert in Graphite Resin (G2), Graphite Antimony (G3), Silicon Carbide (S1) or Tungsten Carbide (T1), ensuring compatibility and performance in various environments.. Thanks to SpliTEM® technology used by MTM907, the sliding rings (stationary and rotating), made in two halves, allow maintenance to be carried out directly in the water and / or with the propulsion axis in position, with a clear saving of time and money.  The Watershield® pneumatic dynamic barrier ring, making Microtem’s MTM907 the most technologically advanced product in the propeller shaft seal market.

The integrated preload system of MTM907 guarantees an extremely simple installation that does not require any particular specialization. From enhanced safety features to streamlined maintenance and installation, the MTM907 propeller shaft seal delivers unmatched performance and reliability, making it the top choice for marine applications worldwide.
