HYDAC SB330 Accumulator | SB330-32A1 | SB330-10A1 | SB330-50A1 | 330 Bar Bladder Type

SB330 Series High-Pressure Bladder Accumulators

Product Overview:

The SB330 series represents the benchmark for pressure pulsation dampening, energy storage, and emergency power in 2026 industrial hydraulic systems. Rated for a maximum working pressure of $330 \text{ bar}$, these bladder-type accumulators are essential for high-performance fluid power. This collection covers core capacities from compact $10\text{L}$ to heavy-duty $50\text{L}$, featuring versatile bladder materials compatible with mineral oils, emulsions, and chemical fluids.

Core Model Specifications:

• SB330-32A1/112U-330A:

  • Volume: $32\text{L}$.

  • Bladder Material: 112U (Nitrile Rubber – NBR, ideal for standard industrial oils).

  • Pressure Rating: $330 \text{ bar}$.

• SB330-10A1/112A6-330A:

  • Volume: $10\text{L}$.

  • Bladder Material: 112A6 (Low-temperature/Special NBR with superior flexibility and gas tightness).

• SB330-50A1/112U-330A:

  • Volume: $50\text{L}$.

  • Features: High-capacity energy storage for heavy forging machinery or large-scale power units.

Key Technical Advantages:

• $330 \text{ bar}$ Peak Pressure Capability: The seamless forged steel shells comply with 2026 international pressure vessel standards, ensuring structural integrity under extreme high-pressure cycles.

• High-Efficiency Bladder Design: Optimized for maximum elasticity and minimum gas permeability. The 112U/112A6 compounds maintain stable Nitrogen pre-charge pressure during intensive charging/discharging cycles.

• Pulsation Dampening & Energy Saving: Effectively absorbs pump flow ripples to reduce system noise and releases stored power during pump unloading, significantly cutting down installed motor power requirements.

• Service-Friendly Construction: Features a top-opening design for rapid bladder replacement without disassembling the entire shell, minimizing maintenance downtime.

• Lifecycle Reliability: Coated with high-quality anti-corrosion finishes to withstand harsh, dusty, or humid industrial environments.

Detailed Technical Specifications:

• Nominal Volume: $10, 32, 50 \text{ Liters}$.

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

• Bladder Compound Code: 112U / 112A6.

• Shell Material: Carbon Steel (Stainless Steel options available).

• Connection Type: A1 (Standard Threaded Connection).
