Hydraulic accumulators are used in many systems to store pressurized fluid and release it when needed. Here are the main applications:

Common applications

• Energy storage — Store hydraulic energy so a smaller pump can be used, or to supply extra flow during peak demand.

• Shock and pulsation dampening — Absorb pressure spikes and reduce vibration/noise in hydraulic systems (e.g., from pumps or sudden valve closures).

• Emergency power — Provide backup hydraulic power if the main pump fails (critical in safety systems).

• Leakage compensation — Maintain system pressure by making up for small internal leaks.

• Thermal expansion compensation — Absorb volume changes in fluid caused by temperature variations.

Specific industry examples

• Oil & Gas / Drilling — Koomey units (BOP accumulators) for emergency closing of Blowout Preventers.

• Automotive —

• Automatic transmission shift control

• Active suspension systems (e.g., Mercedes ABC)

• Brake systems and start-stop systems

• Mobile equipment — Construction, agricultural, and mining machines for smoother operation and energy recovery.

• Industrial machinery — Presses, injection molding machines, and machine tools for consistent pressure and faster cycle times.

• Aerospace & marine — Landing gear, flight controls, and steering systems.

In short: accumulators improve efficiency, safety, smoothness, and reliability in almost any hydraulic system that experiences varying flow or pressure demands.
