We achieve customer-specific solutions including special weight and space-saving accumulators, build with more than six decades of experience with accumulator technology.

Hydraulic Accumulators

A hydraulic accumulator is a pressure vessel that performs many tasks in a hydraulic system. They are used to maintain pressure, store and recapture energy, reduce pressure peaks, power chassis suspensions, and dampen shock, vibration and pulsations.

Under gas pressure, accumulators store a volume of fluid that can be re-fed into the hydraulic system when it is needed. With a rise in pressure within the hydraulic system, the hydraulic accumulator collects the pressure fluid. The result: The gas is compressed. If the pressure falls, the compressed gas expands again and forces the stored fluid into the hydraulic circuit.

Accumulator Applications

Hydraulic components are often subjects to very stiff requirements: High temperatures, extreme pressures, long power-on phases and extended services. Our accumulators demonstrate outstanding characteristics for every area of application. They are the ideal solution to cover peak needs, maintain pressure, store and recapture energy, reduce pressure peaks, power chassis suspensions, and dampen shock, vibration and pulsations.

As a leading technology specialist, Freudenberg Sealing Technologies is in the best position to develop accumulators which meet the requirements of a wide range of specific applications.
