COMPONENTS & SOLUTIONS FOR FLUID HANDLING

DESCRIPTION

The MTM900 was made with the aim to attack the market of small boats and it represents the direct competitor of the known bellows mechanical seal for propeller shaft. We have anyway chosen to lead innovation in this product which, thanks to some tricks, ensures the achievement of high performance. Its design makes it the most compact seal for propeller shaft in the world. The structure of the stationary part, which is provided for cases, is normally manufactured through the use of techno industrial polymers, which guarantee not to run into problems such as ageing , or even the possibility of drilling or fire to which the rubber is subjected. The version MTM901 provided for those who use flanged cases is generally produced in Duplex. It is available from diameter 20 up to 185 mm and it ensures a wide choice of configurations including those with Watershield, the hydraulic system barrier, called MTM902 and MTM903 , where the slip rings are in two halves.
On these last two seals you can use the “repair kit” in two halves, making the operations of maintenance with the boat in the water and without having to uncouple the transmission axis from the joint. The size of the interface are always customized to the needs of the ship owner.
