Cartridge mechanical seal API 682 | MTM 250

for compressors

The MTM250 series of cartridge mechanical seals has been specially designed to be installed on rotary machines as fast as compressors and turbines. It can be realized in different materials, both for the sliding faces and structural materials and it is able to withstand speeds up to 32 m / s. It is available from diameter 40 up to 200mm and it is today mainly used on screw compressors in presence of lubrication. Its design has been optimized thanks to the testing done directly on the field with one of the major manufacturers in the industry, following out the API 619 norm. Today it is used for pumping gas, such as propane, methane, butane and major hydrocarbons. The structure of the MTM250 cartridge mechanical seal is a double type structure with an external safety sealing, SafetyMTM, which becomes the third seal in case of failure of the two main seals.
