Compact Seal CX/DX

The well known and high reliable COMPACT SEAL (CX TYPE, DX TYPE)

Structure

the compact seal (cx type, dx type) is composed of three types of metal rings (flange ring, intermediate ring and cover ring), assembeled by bolts. these metal rings form a casing, and the seal rings are tightly fixed between metal rings. the metal rings are in contact with each other, which assures that the compression of the seal rings is always aintained to the proper gegree, preventing the risk of cracks occurring by excessive pressure on seal rings. these noe seal rings are all identical in design, and normally an aft seal is equipped with these seal rings and forward seal with two seal rigns. the dx type is equipped with one more seal ring, which works as a spare oil seal for emergency use.

  • Aft Seal/Forward Seal

Features

  • Normal condition
  • When the #3 sealing ring fails
  • ●Best seal ring design through highly advanced technologies
    The COMPACT SEAL gives excellent sealing performance, easy handling and stable quality over a long period of time, by utilizing the latest design technology and specially developed seal ring shape and material.
  • ●A seal ring material with superb durability
    The seal rings come in two kinds of materials - VITON (fluoric rubber) and NBR (nitrile-butadiene rubber) – for selection depending on the operating conditions of stern tube seal. The VITON seal ring fitted on the COMPACT SEAL has superb heat resistance, with a special fabric vulcanized on its surface to assure high strength and durability. With its superior structure, the VITON seal ring features the important property of being free from the danger of crack generation under heavily loaded conditions.
  • ●A chrome steel liner with superior abrasion and corrosion-resistance
    A special grade of high-chromium stainless steel is used for this liner.
    This new chrome steel liner is far superior to conventional chrome liners in its abrasion and corrosion resistance, and is highly effective when used as the aft liner where pitting corrosion is liable to occur.
  • ●Repeatedly machinable liner
    Our chrome steel liners are provided with a sufficient machining allowance, so that the worn-out liner can be repeatedly reused machining.
  • ●Double Security SEAL DX Type
    In case of any oil leakage from the #3 seal ring, the #3S seal ring is put into operation by closing two valves on the oil line between the #3 and #3S chamber. The #3S seal ring is safety serviceable for a long period thereafter.
