MTM54

Operative limits

Product description

Microtem MTM54 is a bidirectional unbalanced mechanical seal with a single cylindrical spring and an elastomeric bellows. Suitable for machinery in common service at low and medium pressures, MTM54 complies with UNI EN 12756 standards (formerly DIN 24960) and is available in various material combinations, featuring both stationary rings with a collar and O-rings. Its ease of installation makes it one of the most widely used seals in industrial applications. MTM54 exhibits a high capability to compensate for axial misalignments, which enhances its reliability as a mechanical seal, making it one of the most utilized in the industry. Also, Microtem MTM54 is suitable for some domestic applications given its ease of installation.

Microtem MTM54 is recommended for various types of applications, including containment of white and gray water, across industries such as process, chemical, and energy sectors. It is also used in centrifugal pumps, marine and fuel oil pumps, lubrication and screw pumps, gear and motor pumps, household and garden pumps, pool and dishwasher pumps, lubricated compressors, oils, glycols, and special rotating machinery.
