• The use and application of Ptfe Bellow Mechanical
  Seal are many. If you see operational usage in
  various industries, such as aerospace, defense,
  electrical and electronics industries, mechanical
  and instrumentation, building and construction,
  pharma, medical industries, smelting and
  metallurgy, food and beverage industries,
  textile, and many others.
• PTFE bellow seal adopts the multi-spring
  structure. It is the most widely used mechanical
  seal in the corrosion-resistant pump. The
  operating parameters of these seals differ, based
  on their use and application. Its operating
  temperature range is between -10 to 100 degrees
  Celsius. Their specification ranges between 35 to
  65 mm and operating pressure is less than 0.5MPa,
  their Axial channeling is 0.5mm and their line
  speed is 15m/s.
• Suitable mediums for Ptfe Bellow Mechanical Seal
  is strong acid, strong oxidizing agent, and other
  strong corrosive media in the application.

What are the benefits of PTFE Mechanical Seal

• PTFE bellow seal can be applied to several
  fields.
• PTFE bellow seals for pumps function in
  physiological inertia, sterilization, and
  disinfection.
• PTFE bellow seal design has less friction
  resistance, high pressure, no adhesion, and
  creeping effect
• PTFE bellow seal is easy to install and complete
  in size. It has good resistance to deformation
  and resistance to extrusion.
• PTFE bellow seal has an elastic inner core
  because it has good elasticity, which greatly
  improves the sealing effect of PTFE mechanical
  seal.

Performance of the Welded PTFE Bellow Seals

• PTFE bellows for pumps are very less affected by
  the temperature, its temperature range is wide,
  and the operating temperature is between -190
  degrees Celsius to 260 degrees Celsius.
• PTFE bellows for pumps are very less affected by
  low temperature. Due to its mechanical toughness,
  even at a temperature below -196 C, a PTFE seal
  can maintain 5 elongation.
• Ptfe Bellow Mechanical Seal remains unaffected by
  the environment and frequency. Their volume
  resistance can reach 1018 ohms/cm. The dielectric
  loss of these seals is small, and the breakdown
  voltage of these seals is high.

• Since the blank value of metal elements is very
  low, the content of lead is less than 10-11 g/ml.
• The surface and performance of the PTFE seal
  remain unchanged even after a long exposure.
• PTFE bellow seal is not easily get corroded by
  any chemical reagent except for molten alkali
  metals.
• Their performance and weight are not affected by
  concentrated sulfuric acid, nitric acid, or
  hydrochloric acid, even in the aqua boil. PTFE
  material has a very low coefficient of friction
  with regard to most of the counter-facing
  materials. It means the transition from
  standstill to motion will happen in a smooth
  manner. It will be without a lurch and there is
  hardly ever a stick-slip effect. The qualities of
  PTFE seals are many. Therefore, these seals are
  very widely used in a variety of applications.
