Diaphragms By Rock International

These are flexible, airtight diaphragms that divide two chambers with variable volume and pressure. A feature of the diaphragm is that it can normally bend at the flanging level in both directions. The axial motion is enabled by the differential pressure existing between the two separation chambers or by mechanical controls such as rockers, springs or levers.

CHARACTERISTICS AND ADVANTAGES OF DIAPHRAGMS :
a c Perfect airtight seal
a c Simple assembly
a c Modest production tolerances and surface finishing
a c No sliding and static friction
a c Minimal hysteresis and high degree of sensitivity
a c No need for lubrication
