Diaphragms are flexible barriers that are commonly used to provide a seal and to isolate an enclosure between a moving and stationary part. One example of an application where a diaphragm is used is with a piston working within a cylinder.

Static Diaphragms separate two fluids with little motion or pressure.

Dynamic Diaphragms form a seal between stationary and moving parts,and transmit pressure.

Common Uses:

Diaphragms are used in many different applications, including:

Regulators,Shock absorbers,Pumps,Air compressors,Pressure sensors,gas compressors,Actuators,Flow control valves,Measuring gauges and controls,Turbochargers,Switches,Accumulators
