HYDAC SB330 Accumulator | SB330-32A1/116 | SB330-2.5/112A9 | 330 Bar Bladder

SB330 Series High-Pressure Bladder Accumulators (1L / 2.5L / 32L)

Product Overview:

The SB330 series represents the gold standard for energy storage, pulsation dampening, and fail-safe protection in the advanced hydraulic systems of 2026. This range features capacities from the compact $1\text{L}$ to the heavy-duty $32\text{L}$ models, all rated for an impressive $330 \text{ bar}$. Tailored for diverse fluids and temperature requirements, we provide 112A9, 116, and 112A bladder configurations to ensure ultimate reliability in harsh environments.

Core Model Specifications:

• SB330-1A1/112A-330A:

  • Volume: $1\text{L}$.

  • Bladder: 112A (Ultra-gas-tight NBR), ideal for high-precision micro-servo units.

• SB330-2.5/112A9-330A:

  • Volume: $2.5\text{L}$.

  • Material: 112A9 (Reinforced Synthetic Rubber), offering superior wear and fatigue resistance.

• SB330-32A1/116-330A:

  • Volume: $32\text{L}$.

  • Material: 116 (Specialized FKM or low-temp compound), engineered for corrosive media or extreme thermal conditions.

Key Technical Advantages:

• $330 \text{ bar}$ Peak Pressure Integrity: Shells are forged from premium seamless alloy steel, complying with 2026 international pressure vessel standards to ensure structural security under continuous heavy loads.

• Diversified Bladder Compounds (112A9/116/112A): Depending on the code, these materials offer varied solutions from standard oil resistance to extreme chemical compatibility, extending nitrogen pre-charge retention.

• Instantaneous Dynamic Response: The low-inertia bladder structure instantly neutralizes high-frequency pump ripples ($>10\text{Hz}$), protecting sensitive downstream valves and reducing noise.

• Standardized A1 Interface: Unified threaded ports ensure $100\%$ physical interchangeability with modern 2026 industrial hydraulic systems.

Detailed Technical Specifications:

• Nominal Volumes: $1, 2.5, 32 \text{ Liters}$.

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

• Bladder Compound Codes: 112A9 / 116 / 112A.

• Shell Material: High-Strength Seamless Steel.

• Compatible Mediums: Mineral oils, synthetic fluids, and specialized industrial liquids.
