When it comes to keeping your hydraulic systems running smoothly, accumulators are a key piece of the puzzle. Whether you’re in mining, offshore, or heavy industrial work, downtime isn’t just annoying — it’s expensive. That’s why we recommend HYDAC accumulators: built tough, backed by over 45 years of engineering expertise, and designed to handle Australia’s harshest working conditions.
At Gerrard Hydraulics, we supply and support the full range of HYDAC bladder, diaphragm, and piston accumulators — trusted by professionals across WA and beyond.
Why Every Hydraulic System Needs a Good Accumulator
Accumulators help keep your hydraulic systems running efficiently by storing energy, dampening pressure spikes, and providing backup power during shutdowns or emergencies. The right accumulator doesn’t just protect your equipment — it boosts performance and reduces maintenance headaches.
Explore the HYDAC Range
HYDAC offers a full line-up of hydraulic accumulators, each with specific strengths depending on your system needs.
Bladder Accumulators
Need quick response and high flow rates? HYDAC bladder accumulators are up to the task. Their internal bladder compresses as fluid enters, storing energy and releasing it when pressure drops. They’re a solid choice for:
- Energy storage
- Pulsation damping
- Vehicle suspension
- Leakage compensation
Models like the SB330 and SB600 series handle up to 30 L/s flow and pressures of 345 bar (5000 psi). Plus, options like the SB330B make bladder swaps easy without removing the whole unit from your system — a real time-saver for in-field maintenance.
Also available in corrosion-resistant finishes or full stainless steel for harsh environments.

Diaphragm Accumulators
Compact, efficient, and ideal for more moderate energy storage, HYDAC diaphragm accumulators use a flexible diaphragm to separate gas and fluid. They’re great for:
- Emergency shutdown operations
- Volume compensation
- Suction flow stabilisation
- Noise and shock absorption
They come in welded or bolted designs and a range of diaphragm materials, so they can be customised to suit your fluid type and working conditions. Plus, when paired with a safety block, they comply with European PED and German safety standards.

Piston Accumulators
When you’re working with higher volumes and want precise control, piston accumulators are your go-to. These units feature a floating piston that separates the gas and fluid sections, with finely machined internals and custom sealing systems.
Perfect for:
- Energy recovery
- Pulsation and vibration damping
- Weight balancing and fluid compensation
Available in standard or corrosion-resistant finishes, and even options for long-term energy storage in larger systems.

Helping You Choose the Right Fit
Picking the right accumulator isn’t just about bladder vs piston. Key factors like:
- System pressure
- Fluid type and velocity
- Mounting setup
- Temperature range
- Displacement volume
Each of these factors plays a critical role in determining which accumulator model best suits your system. That’s where our hydraulic specialists step in. At Gerrard Hydraulics, we’ll work closely with you to correctly size and specify the most suitable HYDAC unit for your application — along with the right accessories to streamline both installation and ongoing maintenance.
Built for Offshore and Tough Environments
If you’re in offshore or marine operations, HYDAC accumulators are available with chemical nickel plating or full stainless steel construction — ideal for pressures up to 690 bar in corrosive conditions.
With HYDAC’s recent acquisition of QHP Hydraulics UK, their global reach and support network is stronger than ever.
