Newman Diaphragms LLC. (NDI) NewFlo™ Replacement Diaphragm Fact Sheet

Precision fit for ITT®, Saunders® and Gemü™ valves, the NewFlo™ Replacement Diaphragm is specifically designed as a functional equivalent replacement diaphragm for weir-style valves.

Diaphragm facings use the best modified fluoropolymer, TFM™, which has been shown to have superior steam resistance and outstanding flex life. Elastomer diaphragms and backings use Newman’s high-performance, polymer-rich 2107 compound, the same material used in NSG gaskets, O-rings and OEM parts.

  • Product Differentiators Quality: Newman controls all materials and parts, the best grades from the best manufacturers – and its own proprietary elastomer formulations.
  • Reliability: Rigorous testing by third-party industry experts demonstrates long-term durability through 500 steam cycles and more than 100,000 valve cycles.
  • Maintenance: Less retorquing, plus increased diaphragm longevity equals less maintenance and less plant down-time.
  • Traceability: NewFlo™ Diaphragms are fully batch traceable at the part level – an exclusive in the industry (patent pending).
  • Cleanability: Smoother surface finishes provide better cleanability and sanitization.

Technical Specifications

  • USP Class VI compliant
  • FDA compliant
  • Made from TFM™ from 3M® and Newman’s premium, proprietary elastomer formulation
  • Available in single-piece and two-piece varieties

You may already use validated Newman’s NewFloTM Diaphragm compounds!

Validation of Newman’s diaphragms in your system may not require the rigorous procedures and high cost you may be facing with other replacement diaphragms.

Specifically created to be substituted in your valves as functional equivalents, Newman diaphragms are precision designed and manufactured from the highest quality conforming materials already validated in the industry. We have chosen to use the best modified fluoropolymer, TFM™ (genuine Dyneon™ Hostaflon® TFM™ from 3M®), which has been shown to have superior steam resistance and outstanding flex life.

The EPDM backing is made from Newman’s premium, polymer rich 2107 compound: the same EPDM used in our gaskets, O-rings and OEM parts. You have no doubt validated at least one of our 2107 EPDM products already in use in your processing areas. Newman’s EPDM has demonstrated exceptional chemical and steam resistance and provides enhanced sealing properties. Under testing, Newman’s diaphragms have successfully performed at the lowest bonnet torque values and have not required retorqueing. This benefits service life and reduces maintenance. Newman’s EPDM has shown superior dynamic strength that translates into more cycles before changeout is needed.
