Products / Parker / Cylinders and Actuators / Bladder Accumulator - High Pressure (EHV)
Designed for high pressure hydraulic systems the EHV bladder accumulator is available in carbon & stainless steel, (70 to 690 bar, 0.2 to 57 Litres). Options with a flanged SAE fluid port and for high flow rates are also available.
The EHV bladder accumulator offers a reliable
and efficient solution for storing energy under pressure. Utilizing
comprehensive tools and resources including an applications
database, CAD/CAM, finite element analysis, reliability studies and
simulation we have optimized the design and performance of the
accumulator. Parker Olaer bladder accumulators are suitable for use
in more than 35 countries (all hydraulic accumulators for Europe are
CE marked) and they can meet an extensive range of international and
industry approvals.
The EHV Series bladder accumulator comes with an O-ring seal fluid
port and 7/8" UNF gas connection as standard however other options
are available.
Rigorous product testing and continuous product development help to
ensure our hydraulic accumulators operate at optimum efficiency and
can perform in the most demanding environments. Parker accumulator
accessories such as Safety Blocks, Burst Discs and Permanent
Charging Sets, can aid the safe installation and operation of the
accumulators in any hydraulic system.
In addition to our standard and low temperature elastomer options
Parker has developed the new Xtra Lifetime (XL) rubber mix which
offers a permeation rate 50% lower that the standard mix and an
operational lifetime twice as long as any other bladder available on
the market for the same application. The XL bladder mix features
high mechanical resistance and offers greater reliability therefore
making it ideal for high performance applications. The XL bladder’s
unique design can increase your systems operational uptime and
reduce unscheduled maintenance saving you time and money.
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.
• 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.
• 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.
• Hydraulic Spring/Shock Absorber: A bladder 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.
