HYDAC SB330 Accumulator | SB330-10A1/112A6 | SB330-20A1/112U | 330 Bar Bladder Type

SB330 Series Bladder Accumulators (10L / 20L)

Product Overview:

The SB330 series is the industry benchmark for energy storage and pulsation dampening in the advanced hydraulic systems of 2026. These bladder-type accumulators deliver exceptional response speeds even at an ultra-high pressure of $330 \text{ bar}$. This page features the compact $10\text{L}$ and standard $20\text{L}$ models, equipped with 112A6 and 112U bladder materials optimized for specific temperature ranges—perfect for machine tools, wind turbines, and metallurgical machinery.

Core Model Specifications:

• SB330-10A1/112A6-330A:

  • Volume: $10\text{L}$.

  • Bladder Material: 112A6 (Low-temperature/High-performance NBR), offering superior elasticity and gas tightness in cold environments.

  • Pressure: Rated for $330 \text{ bar}$ maximum working pressure.

• SB330-20A1/112U-330A:

  • Volume: $20\text{L}$.

  • Bladder Material: 112U (Standard NBR), highly durable and ideal for mainstream mineral oil applications.

  • Pressure: Rated for $330 \text{ bar}$.

Key Technical Advantages:

• $330 \text{ bar}$ Peak Pressure Integrity: Shells are forged from premium seamless steel and have passed the 2026 international fatigue tests, ensuring maximum safety during extreme pressure cycles.

• 112A6 Low-Temp Resilience: Specifically engineered for harsh climates, maintaining bladder flexibility at low temperatures to prevent nitrogen leakage caused by embrittlement.

• Instantaneous Dynamic Response: The low-inertia bladder structure instantly absorbs hydraulic ripples, significantly reducing system noise and protecting sensitive downstream components.

• Modular A1 Interface: Features a standard A1 fluid port design, ensuring $100\%$ physical compatibility and rapid installation with modern 2026 hydraulic circuits.

• High-Reliability Gas Valve: Equipped with precision nitrogen check valves, providing excellent gas retention and significantly extending pre-charge maintenance intervals.

Detailed Technical Specifications:

• Nominal Volume: $10 \text{ L} / 20 \text{ L}$.

• Max Working Pressure ($P_{max}$): $330 \text{ bar}$ ($33 \text{ MPa}$).

• Shell Material: Carbon Steel (Anti-corrosion coated).

• Compatible Mediums: Mineral oils, synthetic fluids, and non-corrosive media.

• Connection Style: Standard Threaded A1.
