MTM908evo

Limiti d'impiego

Product description

The propeller shaft seal MTM908 EVO has always been appreciated for its unique features, being the first mechanical seal with an integrated pneumatic barrier for tube connections on the market. As the evolution of MTM908, the propeller shaft seal MTM908 EVO now incorporates semi-split technology as a standard on the stationary ring. This unique feature of the MTM908 EVO propeller shaft seal allows for maintenance to be carried out directly with the vessel in the water and the propulsion shaft in position, resulting in significant time and cost savings.

The applications of the new Microtem MTM908 EVO propeller shaft seal are all within the nautical sector. Here are just a few examples: machinery and applications on small to medium-sized yachts and boats, workboats, patrol boats, tugboats, passenger transport, water-lubricated lines, oil-lubricated lines, and waterjets.
