Mechanical Seals

AS  are single helical coil spring, bi-directional seals developed for dirty media and clogging type applications. Torque transmission from drive collar to spring holder and seal rings is done through sturdy drive lugs. The PTFE double V-packings are spring energised to give perfect dynamic sealing. As all parts are interchangeable, one can convert series AS by changing only secondary seal. This concept is ideal for stock rationalisation.
