MTM913
Limiti d'impiego
Product description
The MTM913 is a frontal mechanical seal for propeller shaft specially designed for installation on oil bath propulsion lines.
Thanks to its compact design together with the split technology of the sliding faces, it becomes the most valid alternative to traditional seals with radial rubber rings.
Connectable to the propeller hub, it does not require a liner as it has no radial parts in contact with the propulsion shaft.
Precisely thanks to this important advantage, on-site maintenance is always possible.
Available from 70 to 600 mm in diameter, it can be made in different dimensional and material variations, making it suitable for navigation even in particularly sandy seas.
