Product description

The propeller shaft seal MTM907 was created to attack the market of medium / large boats and represents the product with the best value for money, available on the world market, in its category. Thanks to its design, it is the world’s most dynamic compact safety barrier split shaft seal. The stationary flange, foreseen 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 spacing and the pitch center distance can be customized according to the needs. The stationary ring can be supplied in Silicon carbide (S / S1) (S1) or in Tungsten carbide (T) (T1) and is foreseen inserted in a 316 stainless steel case. the rotating case provided in 316 stainless steel with insert in Graphite Resin (G2), Graphite Antimony (G3), Silicon carbide (S / S1) (S1) or Tungsten carbide (T) (T1). Thanks to the full-split configuration, it is possible to carry out maintenance directly in the water and/or with the propulsion shaft in place, saving time and money. The Watershield® pneumatic integrated barrier ring makes the MTM907 the most technologically advanced product in the propeller shaft seal market. The integrated preload system guarantEs an extremely simple installation that does not require any particular specialization.
