Hydraulic Accumulators: What are They & How Do They Work?

Accumulators regulate the performance of a hydraulic system by providing an additional volume of system fluid, pressurized by an external gas supply. For industrial applications, there are three types of hydro-pneumatic accumulators: piston, bladder and diaphragm. Each type has particular advantages and limitations, which should be considered when selecting an accumulator for a specific application. We’ll help you understand each type so you can choose the best solution for your system.
