MA25 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.


  • 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
