Parker Hannifin has added two models to its range of piston accumulators. The latest versions in the A Series are available as 125 and 200mm diameter units and form part of a product family for use in industrial and mobile applications, such as suspension systems and pressure maintenance circuits. The accumulators have standard volumes up to 76ltr, with maximum flow rates up to 5700ltr/min and a maximum working pressure of 250bar. They incorporate a compact steel shell and end caps, to allow heat to dissipate efficiently, while the bore of the accumulators is micro-finished to ensure a long seal life. The aluminium pistons have a dished profile allowing extra gas capacity, while maintaining stability in the bore, and permitting a greater volume of fluid to be held. They are supplied with a range of options such as seal compounds, metric and inch mounting styles, gas valves, safety fuses and high flow gas ports for use with remote gas storage bottles.
