Piston Accumulators

Piston accumulators are a versatile component of hydraulic systems, capable of performing several critically important functions:

• Energy Storage – store hydraulic energy under pressure and release it during peak demand, reducing pump operation frequency and increasing system energy efficiency.
• Pressure Stabilization – compensate for pulsations, hydraulic shocks, and pressure fluctuations, ensuring smooth and safe equipment operation.
• Pressure Maintenance – maintain the required pressure even during short pump shutdowns or system changes.
• Emergency Backup – provide the ability to perform critical operations in case of power loss or emergency situations (e.g., load lowering, braking).
• Compensation for Fluid Losses – offset minor leaks without additional load on the pump. 

Freudenberg piston accumulators are designed for operating pressures up to 350 bar, delivering exceptional reliability, durability, and safety even under the most extreme conditions. 
From volumes of 0.2 L to 6 L — the piston hydraulic accumulator can meet any requirements in hydraulic systems thanks to standard or customized designs, a wide selection of connections, materials, seal types, and configurations.
