Accumulators are storage vessels that hold fluid under pressure and are commonly used in fluid power systems to store fluid as energy to be released on demand. When used in hydraulic circuits and machinery, they are sometimes referred to as hydraulic accumulators or hydropneumatic accumulators. Accumulators are also used to eliminate pulsations for a smooth fluid flow and protect systems from hydraulic shock. The most popular design has an internal bladder that acts as a separator between the stored fluid and a compressed gas charge.

BENEFITS:

Accumulators are used in a variety of applications across multiple industries to increase system productivity and lower operating costs.

• Store pressurized fluid as energy
• Temporarily increase/supplement pump flow
• Auxiliary power for equipment cycling, valve closure and emergency shutdown
• Maintain system pressurized
• Makeup fluid for system leakage or bleed down
• Compensate for thermal expansion
• Dampen pulsations and vibrations
• Absorb hydraulic shock/water hammer
