PTFE / PVDF / EPDM diaphragm

  • Description
  • Features
  • Technical specifications

The GEMÜ diaphragm code 71 is a three-piece diaphragm that has been developed for use in industrial applications. The diaphragm is made up of a PTFE face, a PVDF intermediate layer and an EPDM backing. The diaphragm is based on the tried and tested design and dimensions of the code 5M diaphragm with regard to the PTFE face. The diaphragm shows excellent permeation properties against gases.. The diaphragm is extremely resistant to wet chlorine in particular due to the PVDF intermediate layer and the titanium mounting pin.

  • The diaphragm shows excellent permeation properties, as tested and certified by TÜV SÜD
  • Excellent resistance to wet chlorine is tested and confirmed by TÜV SÜD
  • Resistant against virtually all chemicals, such as volatile acids, oxidizing agents and salts
  • Mounting pin made of grade 7 titanium offers tried and tested corrosion resistance against chlorine, bromine and their derivatives
  • Mechanical stop integrated into the diaphragm face mounting pin in order to ensure correct installation
  • The diaphragm has no leakage holes in the EPDM backing in order to improve the permeation properties
  • The design of the diaphragm face is based on the tried and tested contour of the code 5M diaphragm
  • Media temperature:-20 to 100 °C
  • Diaphragm material:PTFE/PVDF/EPDM
  • Diaphragm sizes:10 | 25 | 40 | 50 | 80 | 100
  • Vacuum:up to 70 mbar (absolute)
