• Accumulator type: Bladder
• Volume: 1 L
• Connection: G3/4 (ISO 228)

These values come from the manufacturer's published data. The full list is in the specifications tab.

Applications

• Energy storage
• Absorbing shocks and pulses
• Peak flow supply
• Emergency reserve

How it works

A bladder accumulator stores energy in nitrogen gas. When circuit pressure rises, oil enters the shell and compresses the gas in the bladder; when pressure falls, the gas expands and pushes the oil back. This absorbs pressure peaks and provides peak flow or an emergency reserve.

About the brand

HYDAC is a German maker of accumulators, filters and hydraulic equipment.

Selection and maintenance

Pre-charge pressure is the key setting of an accumulator and must be checked regularly, using nitrogen only. Never use air or oxygen. Discharge the oil pressure of the accumulator before any work on the circuit. Select volume and pressure from a circuit calculation, and check that the bladder material suits the fluid.
