HYDAC SB330 Accumulator | SB330-20A1/24A1/32A1/50A1 | 330 Bar | 112A9 Bladder

SB330 Series High-Pressure Bladder Accumulators (20L – 50L)

Product Overview:

The SB330 series is the industry benchmark for pressure pulsation dampening, energy storage, and fail-safe protection in the advanced heavy-duty hydraulic systems of 2026. This range covers high-capacity models including $20\text{L}, 24\text{L}, 32\text{L},$ and $50\text{L}$. Every unit is equipped with the 112A9 high-performance compound bladder, engineered to provide exceptional response sensitivity and long-term sealing integrity under extreme $330 \text{ bar}$ loads.

Core Model Specifications:

• SB330-20A1/112A9-330A: $20\text{L}$ standard volume, balancing footprint with energy efficiency.

• SB330-24A1/112A9-330A: $24\text{L}$ specification, optimized for specific flow compensation requirements.

• SB330-32A1/112A9-330A: $32\text{L}$ model, providing robust emergency power reserves for medium-to-large power stations.

• SB330-50A1/112A9-330A: $50\text{L}$ high-capacity model, the core energy unit for heavy-duty presses and metallurgical systems.

Key Technical Advantages:

• $330 \text{ bar}$ Safety Certification: Shells are forged from premium seamless steel tubing and comply with 2026 international pressure vessel fatigue standards, ensuring structural security under continuous high-pressure pulses.

• 112A9 Specialized Bladder Material: Formulated with reinforced synthetic rubber for ultra-low gas permeability and superior chemical compatibility. Compared to standard NBR, 112A9 maintains a stable elasticity coefficient under high temperatures or high-frequency impacts.

• Instantaneous Response: The low-inertia bladder structure responds immediately to system fluctuations, effectively dampening high-frequency pump ripples ($>10\text{Hz}$) and protecting sensitive downstream proportional valves.

• Modular A1 Interface: Standardized A1 threaded fluid ports ensure $100\%$ physical interchangeability with mainstream global hydraulic accessories, simplifying maintenance.

• Industrial Durability: High-strength anti-corrosion exterior coating protects the shell in harsh environments featuring moisture, dust, or mild chemical spray.

Detailed Technical Specifications:

• Nominal Volumes: $20, 24, 32, 50 \text{ Liters}$.

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

• Bladder Compound Code: 112A9 (Premium High-Performance Rubber).

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

• Connection Style: Standard A1 Threaded Port.
