The DA diaphragm accumulator offers a reliable and efficient solution for storing energy under pressure and works as an hydraulic spring. Utilizing comprehensive tools and resources including an applications database, CAD/CAM we offer an optimized design and performance membrane accumulator. (all hydraulic accumulators are compliant to 2014/68/EU regulation)
Formerly branded as ELM diaphragm accumulators
Parker diaphragm accumulators (also referred to as membrane accumulators) are gas-loaded accumulators in which separation between the liquid and gas sides is achieved by a flexible diaphragm. They have a compact and lightweight design are available in 2 elastomer mixes; Nitrile and Hydrin (for low temperature working conditions) with a maximum pressure of 350bar (up to 2,8 liters) and volume of 3.5 Litres (up to 250 Bar).
DA accumulator range comes with a bonded seal (BS) fluid port with female or male and female fluid connection and M28x1,5 gas connection.
Accumulator accessories such as Safety Blocks, Clamps, Lock nut, Charging Sets (VGU/SC-VGU), can aid the safe installation and operation of the accumulators in any hydraulic system.
Parker Olaer have developed very sophisticated simulation software to optimize sizing recommendations for hydraulic accumulators. You can download the accumulator sizing software from the Product Support tab.
Hydraulic accumulators are an essential component for the optimum operation of a hydraulic circuit. The accumulator enables:
Volume Control: Absorbs fluid volume variations induced by temperature changes in a closed hydraulic circuit and maintains a rated pressure.

IMPORTANT NOTE: NEVER PRECHARGE THE ACCUMULATOR (ON THE NITROGEN SIDE) AT A PRESSURE EXCEEDING 130 BAR (EXCEPT DA-2,0L-100BAR . Maximal pre-charge value is 100 bar)
