Hydraulic accumulators

HYDAC Technology GmbH can look back on over 50 years′ experience in hydraulic accumulators – in their research & development, design and manufacture.
This covers all hydropneumatic accumulators, from bladder and piston accumulators, right through to diaphragm accumulators and more recently metal bellows accumulators, encompassing new fields of application.
Continual expansion of the individual accumulator types over the years has produced the optimal accumulator product range, which is also supplemented by accumulator protection equipment on the gas and fluid side, such as temperature fuses, bursting discs, gas safety valves and other accessories.

 

HYDRAULIC ACCUMULATORS – ROBUST AND VERSATILE

Accumulators from HYDAC are in widespread use in most sectors of hydraulics.
They are versatile, improve the comfort of your machine, protect your hydraulic system and are used to increase the energy efficiency of hydraulic systems amongst many other functions.

Metal bellows accumulators

 

… are hydropneumatic accumulators with a metal bellows as a separation element between the compressible gas cushion and the operating fluid. The separation element is designed as either a bellow or as a welded diaphragm bellows.

HYDAC metal bellows accumulators are versatile in their application. For example, they are used for pulsation damping on heavy diesel engines or in the chemical industry. In the aeroplane industry, this type of accumulator design is usually used as energy accumulators or for volume compensation, respectively.

 

Essential specifications are:

Nominal volume: up to 6 l,
Permitted operating pressure: up to 210 bar
The following advantages set HYDAC metal bellows accumulators apart:

gas-tight,
maintenance-free,
media-resistant over a wide temperature ranges.
To protect your hydraulic accumulators against
non-permitted temperature increase and/or excessive pressure,
we recommend our safety devices.

Valves

Valves monitor the pressure, flow rate or flow direction of hydraulic fluids. Thanks to a variant-rich programme, HYDAC valves offers almost all of the possibilities for structuring hydraulic systems – whether stationary or mobile. In this area, HYDAC offers cartridge, slip-in, plate mounted, subplates and inline connection valves up to nominal size 63. The performance ranges up to: Qmax = 6000 l/min Pmax = 630 bar

Shut-off valves

 

Shut-off valves from HYDAC are poppet and spool valves for the controlled opening or closing of lines and other hydraulic components. They control inlet, dischrage or outlet of hydraulic fluids.

The flow valve programme encompasses practically all of the functions for influencing the flow rate which are required in hydraulics. Flow valves influence the flow rate in a system by means of mechanical or hydraulic modification of throttle cross-sections. HYDAC offers both manually and hydraulically controlled valves in this area.

Low-noise SC series

 

The low-noise oil-air coolers of the SC series with radial fan are used for cooling small and medium-sized hydraulic systems. The versions with built-in pump (SCA) and filter (SCAF) represent a highly efficient bypass flow cooling and filtration.

 

SC product features:

 

Noise level < 70dB(A) (L version at 1 m distance)
Compact, efficient and high-performance
Simple dismantling of pump, motor and filter
SCA and SCAF series for bypass flow cooling
When the version with pump (SCA) is used, the oil temperature can also be kept constant, independent of the cycle times of the hydraulic system. The SCAF series with integrated HYDAC filter provides additional filtration of the oil.

 

 

OSCA and OSCAF – the optimised series

 

Further development and optimisation of the SCA / SCAF series
More performance with lower noise emissions in a more compact design
Temperature sensors

For recording and evaluating temperatures, HYDAC offers temperature transmitters and temperature switches for installation in pressure lines or for tank mounting.

Temperature measurement transducers record the temperature and convert it into a proportional output signal.

Electronic temperature switches record the temperature, process it and output a switching signal in accordance with the presetting.

Displacement sensors

Electronic path sensors are used for recording cylinder positions in fluid technology systems. Functionality and form of execution are determined by the respective utilisation conditions. In order to fulfil these requirements, HYDAC offers a comprehensive program, from simple attachment sensor to customer-specific, fully integrated sensor.
