Piston Accumulator

HBOETH's piston accumulators consist of a cylinder with a finely processed interior, with screwed-in cover on the gas and fluid side and a piston with special sealing systems. The free-moving piston is a separation element between a compressible gas cushion and the operating fluid.

Highlem's piston accumulators cover 0.25~200 liters, nomial pressure 35MPa and max flow rate up to 5400 liter per minites. Working pressure of the high pressure pistom accumulators is up to140 MPa.

Accumulator shell materials are available with carbon steel, alloy steel, SS, lightweight materials.

Bladder Accumulators
Bladder accumulators consist of a welded or forged pressure vessel, the bladder and the fittings for the gas- and media-side connection.

For special designs or particular applications are possible, for example for very high discharge speeds and high pressures, please contact us directly to learn more.
