API 682 (American Petroluem Institute) is the set of rules that sanction how mechanical seals should be made when they come into contact with hazardous, flammable or toxic substances, through the use of centrifugal or rotary pumps in the petroleum, chemical or natural gas sector.
The legislation regulates the mechanical seals for axles from 20 to 110 mm by establishing precisely which are the categories, type and configurations with which engineers can easily choose the best product for their needs.
The series of mechanical seals MTM500 fits all these positions starting from the simplest solutions such as category 1, including the 1CW-FX (MTM501/502/503) and the type with a floating bearing, 1CW-FL (MTM504).
Moreover, If you search for a solution in categories 2 and 3 there are different configurations: the MTM510 (2CWCW) and the MTM520 (3CW-FB), the MTM521 (3CW-BB) and the MTM522 (3CW-FF). The available materials are various. Furthermore, the wide range of accessories related to the seals are suitable for assembling in presence of the PLAN 02, 11, 13, 21, 23, 31, 32, 52, 53A, 53B, 53C, 54, 62, 65.
