Parker A Series Industrial Piston Accumulators
At Hydraulics Online, we provide a wide range of Parker accumulators, including the Parker A series industrial piston accumulators…
Piston Accumulators up to 80 Litres volume, 200mm Bore, 250 Bar & 350 Bar. Parker A series industrial piston accumulators offer quality design and premium technical features which guarantee optimum performance life.
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.
Features of the Parker A series industrial piston accumulators include:
- 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.
