MA 10 - EPDM - SED Diaphragm


Reinforced EPDM SED Diaphragm

EPDM used in SED Diaphragms is a specifically developed compound reinforced with vulcanized woven fabric inlay. This diaphragm construction achieves higher stability for the diaphragm at elevated temperatures and pressures, such as in critical aseptic applications with SIP steam sterilizing cycles and processes.

In addition, the woven fabric inlay is vulcanized over the embedded compressor stud in order to strengthen the elastomer-metal connection. Thus, the EPDM diaphragm is ideaal for vacuum applications.
All EPDM diaphrgams 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

MA10 is suitable for SED Diaphragm Valves: KMD 289, KMA 295, Steripur 397, KMD 188, KMA 195, Steripur 317
