What are the available sizes and capacities of diaphragm/piston accumulators?

Small-Scale Accumulators: These compact accumulators cater to mobile hydraulic setups and boast capacities ranging from just a few liters (gallons) to approximately 20 liters (5 gallons) or less.
Medium-Sized Accumulators: Suited for both industrial and mobile hydraulic systems, medium-sized accumulators come in capacities spanning from 20 liters (5 gallons) to about 100 liters (26 gallons).
Large Accumulators: Designed to withstand the rigors of heavy-duty industrial applications like hydraulic presses and marine systems, large accumulators can store vast quantities of hydraulic fluid. Capacities here can surpass 100 liters (26 gallons) and extend into the several-thousand-liter range.
Custom and High-Capacity Variants: In specialized scenarios, customized accumulators find their place, tailoring their capacities precisely to the system's unique demands. High-capacity accumulators, common in heavy industries, can hold substantial hydraulic fluid volumes.
Ultra-High Pressure Accumulators: Certain applications, such as waterjet cutting systems and specialized hydraulic test equipment, necessitate accumulators specially built to handle extremely elevated pressures. These accumulators are engineered to endure pressures that can exceed 10,000 psi (690 bar) or more.
Miniature Accumulators: In niche applications, miniature accumulators with minimal capacities carve out their role. You'll find these in devices like medical equipment or precision machinery.
Bear in mind that choosing the right accumulator entails matching its size and capacity precisely to the hydraulic system's requirements. This ensures that the accumulator effectively stores and releases hydraulic energy as needed, preserving the system's stability and performance.
Selecting the proper accumulator size takes into account variables such as system pressure, flow rates, cycle frequency, and installation space availability. Collaborating with a qualified hydraulic engineer or specialist can aid in determining the most fitting accumulator for a specific application. Hydraulic accumulator manufacturers offer comprehensive specifications and recommendations to assist in this selection process.
