Piston accumulator for high performance applications - AP Series - (Europe) AP250EM060H2K

Piston Accumulators up to 300 Litres volume, 360mm Bore, 250 Bar & 350 Bar.Parker AP piston accumulators offer quality design and premium technical features which guarantee optimum performance life.

Parker’s AP piston accumulators are a premium specification product designed for use in high performance applications such as industrial press, die casting and plastic injection moulding, where large volumes of fluid have to be displaced at high speed (250 & 350 bar).

A wide range of bore/stroke combinations enables the piston accumulator with the required volume to be selected in a size that will optimise the use of available space, while metric mountings and a choice of port styles simplify connection. Parker offers a full range of clamps to provide secure mounting.

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:
• Special multi-element sealing systems have been developed to combine good servo application and load holding properties with the wear characteristics required to withstand continuous use at piston speeds of up to 8m/s.
• For unique applications and hostile environments, different designs, materials and coatings can be supplied. Please contact us to discuss custom solutions to individual application requirements.
• 180mm and 250mm bore accumulators feature threaded caps to minimize downtime and simplify maintenance of the accumulator, permitting quick and easy installation of seals. 360mm bore units use a screwed ring to retain the gas and oil caps, reducing the mass of parts handled during maintenance and providing additional protection for the gas valve.
• Carbon steel body and Aluminium piston design.
• High burst test safety factor.

Applications:
• Die casting
• Plastic injection moulding
• Presses
• Machine tools
• Renewable energy

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.
We have included a small selection of part numbers, please download the AP piston accumulator brochure for more information or contact us.
