Diaphragms:
Achieve a reliable seal with flexible response

Diaphragms consists of elastomeric materials and are used for separating two component spaces with a tight yet flexible partition while allowing changes in volume between the two separated spaces.

Diaphragms fulfill three primary tasks:

• A regulating and switching function
  The pressure applied to the diaphragm is converted into a rod force which actuates a switching, regulating or display device.
• A pumping function
  In this case, diaphragms have the opposite function and convert rod force into feed/discharge pressure.
• A separating function
  Spaces having nearly the same level of pressure are separated by a flexible partition diaphragm. This type of separating diaphragm allows changes in volume to take place.
