Bellows Accumulators for 8000 PSI Hydraulic Systems 851914

A Bellows Hydraulic Accumulator offers superior performance and design advantages when compared with accumulators which use elastomeric seals. By using a metal bellows as the dynamic separator between the gas precharge and the hydraulic fluid, a factory precharged, maintenance free accumulator is achieved. The superior performance of the bellows accumulator is due to the heat transfer characteristic of the bellows. Testing has proved that a specially designed bellows can operate in the environment required by 8000 psi hydraulic systems.
