Bladder accumulators consist of a pressure-resistant container in which an elastic bladder reliably separates the gas cushion from the hydraulic medium. Thanks to this design, bladder accumulators react very quickly to pressure changes and are particularly suitable for dynamic applications. They are characterised by high cycle stability and are often used to dampen pressure peaks or provide energy for short periods. Due to their robust behaviour, bladder accumulators are used both in mobile hydraulics and in industrial applications with changing loads.
Hydraulic accumulators from STAUFF
Only available in selected markets
Hydraulic accumulators at STAUFF
Hydraulic accumulators - internationally known as accumulators - are essential components of hydraulic systems. They are used to store energy, stabilise pressure and increase efficiency and operational safety.
Hydraulic accumulators are not part of the global STAUFF standard product range. They are currently sold exclusively by selected STAUFF companies:
In other regions - including Europe, the USA and Canada - hydraulic accumulators are not available from STAUFF.
Note: It is not possible to purchase hydraulic accumulators directly via the central website stauff.com.
What are hydraulic accumulators?
Hydraulic accumulators store hydraulic energy under pressure and make it available again when required. Typical areas of application are
- Storage of energy and pressure maintenance
- Safeguarding emergency and safety functions
- Reduction of pressure peaks and hydraulic shocks
- Damping of noise and vibrations
- Equalisation of pulsations and load fluctuations
Depending on the application and system requirements, different designs, materials, connection variants and pressure levels are used.
Types of hydraulic accumulators
Hydraulic accumulators can be divided into different categories depending on their design principle. The most important types include bladder accumulators, diaphragm accumulators and piston accumulators. We have summarised further information on the first two types of hydraulic accumulator. As piston accumulators are not currently included in our range, we will not go into more detail about these.
Bladder accumulators
Diaphragm accumulator
Bladder accumulators
Diaphragm accumulator
In diaphragm accumulators, the separation of gas and hydraulic medium takes place via a flexible diaphragm. This design is comparatively compact and low-maintenance and is often used where only limited installation space is available. Diaphragm accumulators are particularly suitable for smaller volumes and applications with moderate pressure requirements. Typical applications include pressure maintenance, damping pulsations and supporting functions in hydraulic control and regulation circuits

Frequently asked questions about hydraulic accumulators
Does STAUFF offer hydraulic accumulators worldwide?
No. Hydraulic accumulators are not part of the worldwide STAUFF standard range and are currently only available from selected STAUFF companies.
In which countries are STAUFF hydraulic accumulators available?
Hydraulic accumulators are currently available from STAUFF Australia and STAUFF China.
Can I order hydraulic accumulators via stauff.com?
No. The stauff.com website is for information purposes only. The direct sale of hydraulic accumulators via this platform is not intended.
Does STAUFF also support applications with existing hydraulic accumulators?
Yes, with STAUFF Diagtronics, STAUFF offers manufacturer-independent solutions for monitoring and analysing hydraulic systems - also in conjunction with existing hydraulic accumulators.
What is the difference between hydraulic accumulators and accumulators?
They are different names for the same component. Hydraulic accumulator is the common German term, accumulator is the internationally used term.
