MA40 EPDM SED Diaphragm


Reinforced EPDM SED Diaphragm

EPDM in SED Diaphragms is a specifically developed compound reinforced with a 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

Suitable for SED Diaphragm Valves: : KMD 982, KMA 905, Steripur 907, KMD 402, KMA 395, Steripur 417
