Diaphragm Accumulators

Diaphragm accumulators operate in a similar way to bladder accumulators, however they are supplied assembled as a welded vessel with a pre-installed rubber diaphragm. In comparison to bladder accumulators, diaphragm accumulators are normally manufactured to a lower design pressure. The benefits of STAUFF’s diaphragm accumulators are based on the considerable difference in compressibility between a gas and a liquid, enabling a large quantity of energy to be stored in an extremely compact form. Operating pressures of up to 350 bar (5,000 PSI) enables a liquid under pressure to be accumulated, stored and recovered at any time.
