HYDAC SB330 Accumulator | SB330-2.5A1 | SB330-10A1 | SB330-50A1 | 330 Bar Bladder Type

SB330 Series High-Pressure Bladder Accumulators (2.5L – 50L)

Product Overview:

The SB330 series is the global industry standard 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 bladder-type accumulators deliver exceptional performance. This page features the complete capacity spectrum from the compact $2.5\text{L}$ to the heavy-duty $50\text{L}$ models, featuring specialized NBR (Nitrile Rubber) bladders optimized for various temperatures and media.

Core Model Specifications:

• SB330-2.5A1/112A-330A:

  • Volume: $2.5\text{L}$.

  • Specs: Compact design with 112A ultra-gas-tight bladder, ideal for small high-pressure power units.

• SB330-10A1/112A6-330A:

  • Volume: $10\text{L}$.

  • Bladder Material: 112A6 (Low-temperature/High-performance NBR), engineered for extreme resilience in cold operating conditions.

• SB330-50A1/112U-330A:

  • Volume: $50\text{L}$.

  • Specs: High-capacity model with 112U standard wear-resistant bladder for massive pulse absorption and emergency power reserves.

Key Technical Advantages:

• $330 \text{ bar}$ Industrial Pressure Integrity: Shells are forged from premium seamless steel, complying with 2026 international pressure vessel standards to ensure zero-leakage safety under extreme pressure cycles.

• Pro-Grade Bladder Compounds (112A/U/A6): Features ultra-low gas permeability and superior fatigue resistance. Different compound codes ensure stable operation from $-15^\circ\text{C}$ up to $+80^\circ\text{C}$.

• Instantaneous Response: The low-inertia bladder structure responds immediately to hydraulic shocks, protecting sensitive valve groups and significantly reducing circuit noise.

• Modular A1 Interface: Standardized threaded ports ensure $100\%$ physical compatibility with mainstream global hydraulic accessories, slashing installation and maintenance downtime.

• Industrial Durability: High-quality exterior coating provides excellent protection in harsh, corrosive environments.

Detailed Technical Specifications:

• Nominal Volumes: $2.5, 10, 50 \text{ Liters}$.

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

• Bladder Compound Codes: 112A / 112U / 112A6.

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