1. HYDAC ACCUMULATOR TECHNOLOGY
FLUID ENGINEERING EFFICIENCY VIA ENERGY MANAGEMENT.
HYDAC Accumulator Technology has over
50 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:
z Energy storage,
z Emergency and safety functions,
z Damping of vibrations, fluctuations,
pulsations (pulsation damper), shocks
(shock absorber) and noise (silencer),
z Suction flow stabilisation,
z Media separation,
z Volume and leakage oil adjustment,
z Weight equalization,
z Energy recovery.
Using accumulators improves the
performance of the whole system and in
detail this has the following benefits:
z Improvement in the functions
z Increase in service life
z Reduction in operating and maintenance
costs
z Reduction in pulsations and noise
On the one hand, this means greater
safety and comfort for operator and
machine.
On the other hand, HYDAC accumulators
enable efficient working in all applications.
