HYDAC SB330 Accumulator | SB330-32A1/112U | SB330-10A1/663U | 330 Bar Bladder Type

SB330 Series High-Pressure Bladder Accumulators (10L / 32L)

Product Overview:

The SB330 series is the global industry benchmark for energy storage, pressure pulsation dampening, and fail-safe protection in the advanced hydraulic systems of 2026. Rated for a maximum working pressure of $330 \text{ bar}$, these units deliver exceptional response speeds. This page features the compact $10\text{L}$ and standard $32\text{L}$ models, equipped with 112U and 663U bladder materials optimized for diverse industrial fluids—perfect for machine tools, wind turbines, and heavy-duty presses.

Core Model Specifications:

• SB330-32A1/112U-330A:

  • Volume: $32\text{L}$.

  • Bladder Material: 112U (Standard NBR), offering superior oil resistance and versatility.

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

• SB330-10A1/663U-330A:

  • Volume: $10\text{L}$.

  • Bladder Material: 663U (High-Performance/Specialized Compound), designed for specific chemical compatibility or harsh operating conditions.

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

Key Technical Advantages:

• $330 \text{ bar}$ Peak Pressure Integrity: Shells are forged from premium seamless alloy steel and comply with 2026 international pressure vessel fatigue standards, ensuring maximum safety during continuous heavy-load pulsations.

• Advanced Bladder Technology (112U/663U): Formulated with specialized synthetic rubber for ultra-low gas permeability, ensuring long-term nitrogen pre-charge stability and significantly extending maintenance intervals.

• Instantaneous Dynamic Response: The low-inertia bladder structure responds immediately to hydraulic shocks, protecting sensitive downstream proportional valves and significantly reducing circuit noise ($>10\text{Hz}$).

• Modular A1 Interface: Standardized A1 threaded fluid ports ensure $100\%$ physical interchangeability with modern 2026 industrial hydraulic stations, simplifying on-site service.

• Industrial Durability: High-quality anti-corrosion exterior coating protects the shell in harsh, dusty, or humid environments.

Detailed Technical Specifications:

• Nominal Volumes: $10 \text{ L} / 32 \text{ L}$.

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

• Bladder Compounds: 112U / 663U.

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

• Connection Style: Standard A1 Threaded Port.
