Positive displacement hydraulic accumulators serve as self-contained sources of hydraulic pressure. Our gas-charged piston-based accumulators allow hydraulic systems to quickly respond to changes in pressure demand and can also smooth out pulsation from pumps and other cycling devices up and downstream. Using accumulators often allows for the use of smaller pumps, providing for a lower system weight and footprint. Our innovative design features a hydraulic reservoir made with proprietary composite fiber wrapping over a thin metal sleeve. This provides for pressure ratings to 3000 PSIG, while saving up to 40% of the weight found in competitive products. Dual piston seals provide for positive separation of the charging gas from the process media.
Our positive displacement hydraulic accumulators are used in hydraulic application where attenuating pulsations in line pressure is needed and can also be used as backup hydraulic power for thrust vector control (TVC) actuators.
