Product description

Mirotem’s MTM901 propeller shaft seal was created and engineered to dominate the nautical market for medium to large boats, offering unparalleled value for money globally. Its innovative design positions it as the most compact propeller shaft seal available worldwide, setting a new standard for efficiency and performance.

MTM901 has a lot of key features, that make this seal unique: thanks to its design, MTM901 is one of the most compact propeller shaft seal in the world. The stationary flange, provided for those who use flanged stern tube, is by standard in 316 Stainless Steel and can accommodate up to 6 radial holes (optional) in which it is possible to connect: an additional flushing, a temperature sensor, a vibration sensor (triaxial), a pressure sensor or a dedicated vent line. The size of the flange, the number, the center distance and the size of the anchor pins can be customized according to need. The stationary ring of Microtem’s MTM901 propeller shaft seal can be supplied in graphite resin (G) or in antimony graphite (G1) and is provided monolithic or inserted in a 316 stainless steel case. The rotating ring is fixed to the propulsion shaft with a series of grains (up to diameter 100) or with a clamp (over diameter 100) and is available in 316 stainless steel, Duplex or Super Duplex. Thanks to its integrated preload system, the installation is extremely simple and does not require any particular specialization. The MTM901 selected with the dynamic inflatable barrier Watershield, it guarantees the maximum safety onboard.

Whether navigating tranquil waters or challenging seas, the MTM901 propeller shaft seal guarantees exceptional performance, reliability, and safety, making it the preferred choice for discerning boat owners and marine professionals worldwide. MTM901 is suitable for all kind of vessels, from medium to large.
