MTM190

Operative limits

Product description

Single mechanical seal, balanced, external, independent of the direction of rotation with multi-spring configuration. The MTM190 Series represents the mechanical seal with the most reduced axial dimensions. Thanks to the possibility to be configured with all the stationary rings, it is interchangeable with all the most famous mechanical seal on the market today.Source of proud, it has been defined by the industry as “Universal Seal”. Made according to UNI EN 12756 ex DIN 24960 it is available in different materials including plastics such as PEEK and DIFLON. Thanks to its design it is able to resist up to 64 bar of pression.
