The Parker EHV bladder accumulators are available from 207 to 250 bar in Carbon Steel. Also available is the EHVF series with Flanged SAE Fluid Port.

Gas loaded 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.

Market Sectors:
• Industrial (metal forming, plastic press, heavy industry, tooling machine, hydraulic power units, test bench...)
• Energy (Oil & Gas, Wind Power, Nuclear Power, Renewable Energy)
• Marine (ship equipment, cranes)
Formerly branded as Olaer.
• Mobile (handling construction, mining...)

We have included a small selection of part numbers for this series. Please download the EHV bladder accumulator brochure for more information or contact your local Parker sales company for more information.

The EHV series comprises a forged steel shell, a rubber bladder and an O Ring fluid port assembly.

Parker offer a full range of accumulator accessories and maintenance equipment including safety blocks, charging sets, brackets & clamps, adaptors and seals.

Parker has developed very sophisticated simulation software to optimize sizing recommendations for hydraulic accumulators. You can download the sizing software from the Product Support tab above.

CAD files can be downloaded from the Support tab at the top of the page.
