MA 25 - EPDM - SED Diaphragm


Reinforced EPDM SED Diaphragm

EPDM used for SED Diaphragms is a specifically developed compound reinforced with vulcanized woven fabric inlay.

In addition, the woven fabric inlay is vulcanized over the embedded compressor stud in order to strengthen the elastomer-metal connection. This construction gives it higher stability at elevated temperatures and pressures, such as in critical aseptic applications with SIP steam sterilizing cycles and processes. But it is also ideal for vacuum applications.
All EPDM Diaphragms of SED are always manufactured in the molded open position.


  • Woven fabric reinforcement between two elastomer layers
  • Increased lifetime expectancy under steam
  • Ideal for vacuum applications
  • One piece, molded open
  • Diaphragm is interchangeable with all SED diaphragm valves
  • Batch traceable by a set of unique codes molded into the diaphragm dvary
