Hydraulic accumulators

Hydraulic accumulators

HYDAC Technology GmbH has over 50 years’ experience in the research & development, design and production of hydraulic accumulators.
This includes all hydropneumatic accumulators, from bladder accumulators and piston accumulators to diaphragm accumulators and now also metal bellows accumulators for advanced fields of application.
With the individual types constantly expanded on, over the course of the years an optimum range of accumulators has come into being that is also complemented by gas- and fluid-side accumulator protection, such as temperature fuses, bursting discs, gas safety valves and other accessories.

Hydraulic accumulators – robust and versatile
Wherever hydraulic tasks need to be performed, hydraulic accumulators from HYDAC can help. They are flexible in use, increase the comfort of your machine, protect your hydraulic system and are used to raise the energy efficiency of hydraulic systems and for many other tasks.
Example applications include:

energy storage,
emergency functions and safety functions,
damping of vibrations, pulsations (pulsation dampers), shocks (shock absorbers) and noise (silencers),
suction flow stabilisation,
chassis suspension,
volume compensation and leakage compensation,
weight equalisation,
energy recovery, recuperation and also
media separation.

Bladder accumulators

Robust, autonomous, for high discharge speeds: select the right bladder accumulator for your hydraulic application.
To product overview

Piston accumulators

HYDAC piston accumulators can be customised with a chosen diameter and nominal volume. More details can be found here.
To product overview

Diaphragm accumulators

HYDAC diaphragm accumulators are designed as modules and thus provide the right pressure stages for your application: optimum dimensioning also reduces environmental impact.
To product overview

Hydraulic dampers

Hydraulic dampers reduce, in particular, pulsations, pressure spikes and noise. A small selection of our dampers and silencers is presented here.
