Diaphragm Accumulators

A diaphragm accumulator performs the same function as a bladder accumulator, however, it operates like a membrane. A poppet is molded into the bottom of the diaphragm to prevent its extrusion through the fluid port.

Diaphragm accumulators are frequently used where small volumes are required, weight is important, a higher pressure ratio is required (up to 10:1) or low cost is a prime factor.

Applications with corrosive environments may require a coating or be manufactured from stainless steel.
