MTM121

Operative limits

Product description

Microtem MTM121 is a single, balanced mechanical seal, independent of the direction of rotation, with a single wave spring. MTM121 is manufactured according to UNI EN 12756 (formerly DIN 24960), the standard that defines the main dimensions for the internal installation of mechanical sealing devices.

The versatility in material configurations and the design of the wave spring of the MTM121 seal allow it to be widely used not only in heavy-duty machinery but also in the presence of highly viscous liquids. Thanks to its balanced design, the MTM121 mechanical seal can withstand high operating pressures and is available in various configurations, including multi-spring. Additionally, the MTM121 mechanical seal features high torsional resistance and a reduced axial footprint, making it universally applicable. This is a feature that allowes to mainatin costs under control in a great deal of diferent projects.
