MTM711

Limiti d'impiego

Product description

MTM700 are the series of double cartridge mechanical seals for general and medium-heavy applications, interchangeable with all other cartridge solutions on the market. In particular, the MTM711 belongs to the line of the most performing solutions of the series of double cartridge seals, able to work in contact with highly viscous fluids or in the presence of solid parts without suffering any damage. It is balanced and independent of the direction of rotation. It is easy to install thanks to its compact design, it is replaceable to the most famous cartridge solutions on the market without having to make any changes to the machines in which it is installed. It does not cause damage to the shaft and is not damaged due to dirt during assembly. It is provided in materials such as Hastelloy, Iconel and Duplex.
