Full Product Description

The EHP Piston Accumulators are manufactured in Carbon and Stainless Steel and are available with a wide selection of bore sizes and approvals. Ideally suited for Industrial applications (150 & 350 bar/ 80 to 540mm range of bore sizes, as standard).

A more bespoke range of EHP piston accumulators is available offering higher pressures 250 bar to 3,000 bar and any volume capacity up to 1350 litres.

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.

Key Markets:
• Industrial
• Mobile
• Renewable Energy
• Power Generation
• Oil & Gas
• Marine

Features/Benefits:
• Standard temperatures range from -15°C to 100°C, piston accumulators can also be manufactured to operate in temperatures of -40°C to 150°C. Temperatures outside this range can be met to suit specific applications.
• A wide range of international approvals and materials are available to ensure your piston accumulator is suitable for even the harshest environments and powerful applications. Our purpose built production area incorporates; Ultrasonic cleaning of components; tube washing bath with capability of up to 4 metres long x 750mm diameter.
• Parker piston accumulators can be designed and built to your specified criteria and can therefore meet any space limitations you may have. For unique applications and hostile environments, different designs, materials and coatings can be supplied. An extensive selection of connection ports can be incorporated to suit your requirements.
• A dedicated technical team uses the latest 3D SolidWorks and Autodesk Inventor software driven by calculation programs (linked to EN14359, ASME VIII, Selo, NR13, CUTR, DNV GL, ABS and PD5500) to reduce design times and provide technical customer support.

Applications:
• Industrial Machine Tools
• Mining
• Die casting & Press
• Renewable Energy
• Wind power

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 actuators, pumps, external forces or other components to control shock, pressure and flow rates in the hydraulic circuit.
• Volume Control: Compensation of fluid volume variations induced by temperature or altitude 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, ensure safety or to realize a full hydraulic cycle.
• Hydraulic Cushioning: A piston accumulator can act as a gas-spring suppressing shocks, noise and vibrations in hydraulic systems.
We have included a small selection of part numbers, please download the EHP piston accumulator brochure for more information or contact your local Parker sales company.

Parker offer a full range of accumulator accessories and maintenance equipment including safety blocks, charging sets, brackets & clamps, adaptors & seals and piston position indicators, burst disc, fuse.
