Products / Parker / Cylinders and Actuators / Diaphragm Accumulators - ELM Series
Diaphragm accumulators are inexpensive, compact and lightweight and are ideally suited where weight and space is an important consideration. Ideally suited to Mobile -Agricultural and Construction markets (140 to 350 bar/ 0.075 to 3.5L).
The ELM diaphragm accumulator offers a reliable and efficient
solution for storing energy under pressure and 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)
ELM 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).
ELM 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), 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.

Function:
Hydraulic accumulators are an essential component for the optimum
operation of a hydraulic circuit. The accumulator enables:
• Energy Storage: Saves energy without loss and redistributes when
required therefore reducing installed power.
• Hydraulic Spring/Shock Absorber: A membrane accumulator can act as
a gas spring suppressing shocks and vibrations in hydraulic systems
of lifting vehicles (e.g. Forklift trucks) and maintains real
suspension of the load on a gas spring.
• Emergency Energy Storage: In case of failure of the main energy
source, these accumulators can provide sufficient energy to complete
an operation or to realize a full hydraulic cycle (example-brake or
steering system) .
• Pressure Compensation: Absorbs pressure spikes from pumps or other
components to control pressure and flow rates in the hydraulic
circuit.
• Volume Control: Absorbs fluid volume variations induced by
temperature changes in a closed hydraulic circuit and maintains a
rated pressure.
