Parker DA series diaphragm / membrane accumulators are inexpensive, compact, lightweight, low maintenance and ideally suited where weight and space is an important consideration. They were formerly known as ‘ELM’ diaphragm accumulators. They offer a reliable and efficient solution for storing energy under pressure and work as a hydraulic ‘spring’.
Parker DA accumulators are gas-loaded with separation between the liquid and gas sides achieved by a flexible diaphragm. They are available in 2 elastomer mixes: Nitrile and Hydrin (for low temperature working conditions) with a maximum pressure of 350 bar (up to 2.8 litres) and volume of 3.5 litres (up to 250 bar).
Parker DA accumulators come with a bonded seal (BS) fluid port with female or male and female fluid connection and M28 x 1.5 gas connection.
