Hydraulic accumulators are essential components in fluid power systems. They store energy in the form of pressurized fluid and release it when needed. Their key roles include compensating pressure variations, ensuring flow continuity in case of pump failure, absorbing shocks or pulsations, and enhancing system efficiency.

On fluid-hub, you’ll find a comprehensive range of accumulators designed to ensure safety, reliability, and consistent performance, even under the most demanding operating conditions. All models comply with industry safety standards and are suitable for both static and dynamic applications.

Our range includes four main subcategories:

• Bladder accumulators: ideal for applications with frequent charge/discharge cycles. The elastomer bladder separates fluid and gas, ensuring long service life and easy maintenance.

• Diaphragm accumulators: compact and responsive, they are well-suited for systems with limited volume or where fast reactions are required. The elastic diaphragm provides dynamic and reliable operation.

• Welded diaphragm accumulators: maintenance-free and compact, they are designed for applications where diaphragm replacement is not needed. Their welded body minimizes the risk of leakage.

• Accumulator accessories: charging valves, fittings, brackets, safety kits, and pressure indicators to complete installation and ensure optimal system operation.

By absorbing pressure and volume fluctuations, accumulators contribute significantly to the system’s energy balance, improving operational stability and reducing wear on components. They are widely used in industrial plants, mobile machinery, marine applications, and precision hydraulics.

Accumulators work in synergy with the other components of the hydraulic circuit. At fluid-hub you can also find the hydraulic pumps whose pulsations are dampened by the accumulator, the hydraulic valves that regulate flow in the circuit, and the fittings needed to connect the accumulator to the system.
