MTM20

Operative limits

Product description

Microtem MTM20 is an unbalanced mechanical component seal with a conical spring, dependent on the direction of rotation, suitable for common machinery services operating at low and medium pressures. Microtem’s MTM20 is manufactured according to UNI EN 12756 standards (formerly DIN 24960) and is available in various material combinations. The MTM20 component seal configuration includes different types of stationary rings to make it suitable for any application, as shown in the dedicated diagram.

Microtem’s MTM20 is a mechanical component seal that adapts to various fields of use, particularly for different types of pumps including lubrication pumps, gear pumps, centrifugal pumps, dishwasher pumps, garden pumps, and pool pump seals. Additionally, the use of MTM20 seals extends to the food and pharmaceutical industries, the energy sector, the process industry, as well as applications that deal with preventing and avoiding the leakage of white and gray water. The application area of the MTM20 seals also includes fuel oil and machinery that need to contain liquids or substances with low solid content.
