Bladder accumulators are essential components for maintaining stability, efficiency, and safety in hydraulic systems. Their main function is to store energy in the form of pressurized fluid, releasing it when required to help dampen pressure fluctuations, absorb shocks, and compensate for volume changes or losses.

This type uses a flexible internal bladder (typically made of nitrile rubber or similar elastomer) housed in a high-strength metal shell pre-charged with gas. When fluid enters the accumulator, it compresses the gas via bladder deformation, effectively storing hydraulic energy. The discharge is immediate, making bladder accumulators extremely responsive in dynamic conditions.

At fluid-hub, we offer high-quality bladder accumulators built to deliver durability, low maintenance, and excellent performance in demanding environments. Our products are compatible with standard hydraulic fluids and suited for continuous operation.

Other available accumulator types:

• Diaphragm accumulators: ideal for compact, fast-response applications using an elastomer diaphragm to separate fluid and gas.

• Welded diaphragm accumulators: maintenance-free sealed version, suited for permanent or safety-critical installations.

• Accumulator accessories: charging kits, safety valves, brackets, and all necessary parts for safe and reliable integration.

For monitoring precharge and operating pressure, we recommend pairing the accumulator with dedicated pressure switches. In circuits requiring overpressure protection, it is also essential to install on-off pressure regulating valves upstream of the accumulator.
