Hydraulic accumulator is a pressure storage device to which an external source of mechanical energy is applied to an incompressible hydraulic fluid held in the reservoir.  The Hydraulic accumulator gives the hydraulic system the ability to cope with demand extremities and smooths out fluctuations in operational demand. The most common type of Hydraulic Accumulators are hydro-pneumatic accumulators also known as compressed gas accumulators. Many options of Hydraulic accumulators are available, and we can help you select the right model for your application.
