MTM120

Operative limits

Product description

Microtem MTM120 is a single, unbalanced mechanical seal, independent of the direction of rotation, with a single wave spring. MTM120 is manufactured according to UNI EN 12756 standards (formerly DIN 24960), which defines the main dimensions for the internal installation of single and multiple mechanical sealing devices. Its versatility in material configurations and the design of the wave spring allow it to be widely used not only in machinery for heavy-duty services at medium pressures, but also in the presence of highly viscous liquids.

The MTM120 component mechanical seal from Microtem is available in various configurations, making it ideal for many different applications. The MTM120 has high torsional resistance and a reduced axial footprint, making it universally applicable, and it is also available in a multi-spring configuration.
