Accumulators for Offshore Hydraulic
applications with special coatings or stainless steel up to 690bar.

HYDAC has also acquired QHP Hydraulics in the

HYDAC Accumulator Technology can reflect on
over 45 years experience in research & development, design and production
of Hydac accumulators. Bladder, piston, diaphragm and metal bellows
accumulators from HYDAC together form an unbeatable range and as components
or units, support hydraulic systems in almost all sectors.

The main applications of our accumulators are:

Energy storage

Emergency and safety functions

Damping of vibrations, fluctuations,
pulsations (pulsation damper), shocks (shock absorber) and noise (silencer)

Suction flow stabilisation

Media separation

Volume and leakage oil adjustment

Weight equalization

Energy recovery

Using accumulators improves the performance of
the whole system and specifically this has the following benefits:

Improvement in the functions, Increase in
service life, Reduction in operating and maintenance costs, Reduction in
pulsations and noise.

Basic criteria, such as:

Design pressure

Design temperature

Fluid displacement volume

Discharge/ Charging velocity


Acceptance specifications

Mounting options are important parameters
required for sizing the correct accumulator.

In addition, the knowledge developed by our
accumulator specialists will help to select the right type of accumulator. The
comprehensive range of HYDAC accessories simplifies installation and
maintenance according to the specification.
