Rubber Diaphragms


Rubber Diaphragms

A diaphragm seal is a flexible membrane that seals and isolates an enclosure. The flexible nature of this seal allows pressure effects to cross the barrier but not the material being contained. Diaphragms are also used to protect a process fluid from the pressure sensor.

The reinforced membrane transfers energy and separates two medium.

  • Works under two different pressures / liquids / gases.
  • Transfers pressure from one side to another.


Selection Parameters :

  • Contact Medium
  • Working Atmosphere
  • Frequency of Deflection
  • Engineering Design


Rubber Diaphrams are also manufactured from over 15 polymers including:  Nitrile / Buna-N (NBR), Fluorocarbon (Viton®, Fluorocarbon (FKM), Silicone (VMQ), Fluorosilicone (FVMQ), Polyurethane (AU/EU), Natural Rubber (NR), Ethylene Propylene (EPDM), Hydrogenated Nitrile Rubber (HNBR), Styrene Butadiene Rubber (SBR), Chloroprene (Neoprene®), etc.
