Today, Tumedei is one of the world leading manufacturers of fabric reinforced diaphragms for a range of applications and industries.

  • Fabric reinforced diaphragms
  • Rolling diaphragms
  • Rubber diaphragms
  • Convoluted diaphragms
  • Deep convoluted diaphragms
  • Rubber polymers ranging from NBR, EPDM, CR, ECO, FKM, VMQ Silicone and other.
  • Material from 40 to 80 Shore A.
  • Materials with international drinking water approvals available, please refer to our material section.
  • Hardness can be maintained under certain production conditions within +/-3 shore A. However normal hardness tolerance is usually +/-5 IRHD.
  • Dimensional tolerances can be maintained under certain production conditions below class M1 (ISO3302).
  • The ability to produce diaphragms bonded with either plastic and/or metal plates or inserts.

Rolling diaphragms are typically tall reinforced diaphragms, the ratio height / diameter can make it a challenging product to produce.
