What Are Hydraulic Accumulators and Why Do They Matter?
Hydraulic Accumulators store hydraulic energy and release it when your system needs instant power. They absorb shocks, damp pulsations, and act as emergency fluid reserves - leading to fewer shutdowns, lower maintenance costs, and longer equipment life.
Designed for heavy - duty hydraulic systems, our accumulators help cut downtime, protect critical components, and ensure consistent performance in demanding industrial operations.

Accumulators are vital components of hydraulic systems that store energy by holding liquid under pressure. They typically use compressed gas (such as nitrogen) separated from hydraulic fluid by a bladder, piston, or diaphragm. When system pressure rises, fluid enters the accumulator and compresses the gas. When pressure drops, the stored energy is released, providing immediate power, stability, and efficiency to the system.
- Bladder Accumulators: Ideal for applications requiring high flow and fast response times.
- Piston Accumulators: Suitable for high-pressure systems that need large fluid volumes.
- Diaphragm Accumulators: Perfect for compact applications with moderate pressure requirements.
- Energy storage for peak demand and reduced pump size
- Shock and pulsation dampening for smoother operation
- Emergency backup power in case of system failure
- Improved efficiency and faster response times
- Compensation for leakage and thermal expansion
- Enhanced system stability and overall performance
