Piston accumulators are hydraulic devices that utilize a free-floating piston to separate a hydraulic fluid from a pressurized gas like nitrogen. The gas is pre-charged, enabling the accumulator to store energy and release it as needed, helping to maintain pressure stability in hydraulic systems. DURAfilter offers high-quality hydraulic piston accumulators that can handle high flow rates and higher gas compression ratios per second. We provide hydraulic piston accumulators from leading brands, such as Bolenz & Schäfer (BSD) and Eppensteiner (EPE). These devices are designed for use in industrial applications requiring precise pressure control.
Features of Piston Accumulators
- Our piston-type accumulators ensure efficient energy storage, pulsation dumping, and pressure surge control.
- Many piston accumulators meet DIN/ISO 9001 standards and are certified to European Pressure Equipment Directive (PED) 97/23/EC.
- Equipped with durable carbon-steel housings for normal environments and stainless-steel options for corrosive environments.
- Hydraulic piston accumulators are available in a full range of capacities with custom sizing options.
- They deliver compact performance ideal for tight spaces, extreme climates, and continuous operation.
- Each unit is equipped with the necessary safety and control components, including valves, sensors, and fittings, ensuring reliable monitoring and secure operation in hydraulic systems.
- Designed for long-term use in 24/7 operations, these accumulators require minimal upkeep while delivering consistent performance with low energy loss.
- We offer full accumulator stations, including multiple piston units and auxiliary pressure vessels plus mobile expertise, sizing tools, and system simulation tailored to meet each installation’s exact performance needs.
