Safety Warning

Item Information

Premium quality design and technical features guarantee optimum performance and service life from every model, while differing wall thicknesses to suit 250 or 350 bar working pressures allow the designer to specify precisely the right performance envelope for the application.

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.

Markets:
• Industrial
• Oil & Gas
• Energy

Features/Benefits:
• Effective heat dissipation is vital for long seal life. Compact, rugged steel shell and end caps allow heat to dissipate efficiently, while the bore of the accumulator is micro-finished to maximise seal life.
• Rapid response in high cycling applications is assured by Parker’s lightweight piston design. The dished profile of the aluminium piston gives extra gas capacity while maintaining stability in the bore, and permits a greater usable volume of fluid. Piston position sensors, available as an optional feature, enable the condition of the accumulator’s precharge to be monitored.
• Long service intervals are made possible by total separation of oil and gas, even under the most severe operating conditions. Downtime is minimised by the use of threaded caps to simplify maintenance of the accumulator, permitting quick and easy installation of seals.
• Parker’s A series piston accumulators feature a wide piston seal assembly comprising a unique five-bladed V-profile O-ring with back-up washers, which eliminates seal roll-over even in high speed applications. The V-O-ring holds full pressure throughout long idle periods between cycles, providing dependable, full pressure storage of hydraulic energy.
• Enhanced nitrogen gas retention.
• High cycle rates and high flow rates.
• Designed for long life – non sudden failure.

Applications:
• Die casting
• Industrial Hydraulic Power Units
• Machine Tools
• Automotive
• Marine & Offshore
• Wind Energy
• Transport Rail & Truck
• Mobile Construction & Agriculture
• Construction Equipment

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 piston 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.
