Metal bellows accumulators

HYDAC metal bellows accumulators are the high-end solution when it comes to hydraulic accumulator technology. Unlike conventional accumulators, these accumulators use metallic bellows as the separation element between nitrogen and hydraulic fluid. This design guarantees zero gas leakage and makes the accumulator maintenance-free across its entire service life. They are the first choice when elastomers (diaphragms or bladders) reach their physical limits because of extreme temperatures or chemically aggressive media.
