Products / Parker / Cylinders and Actuators / Piston Accumulator - EHP Series
The EHP piston accumulators are manufactured in Carbon & Stainless Steel and are available with a wide range of bore sizes to PED 2014/68/EU. Suitable for Industrial, Marine, Oil, Gas & Energy applications (250 & 350 bar/ up to 540mm bore as standard).
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.
