SB330 Series High-Pressure Bladder Accumulators (Specialized Compounds)

Product Overview:

The SB330 series is the industry benchmark for pressure pulsation dampening, energy storage, and fail-safe protection in 2026 heavy-duty hydraulic systems. Rated for a maximum working pressure of $330 \text{ bar}$, these bladder-type accumulators are essential for high-performance fluid power. This page features core capacities from $20\text{L}$ to $50\text{L}$, including models equipped with specialized bladder compounds optimized for fire-resistant fluids, water-glycols, and extreme operating temperatures.

Core Model Specifications:

• SB330-24A1/114A9-330A:

  • Volume: $24\text{L}$.

  • Bladder Material: 114A9 (Specialized synthetic rubber), designed for specific chemical compatibility and superior gas tightness.

• SB330-20A1/112A12-330A:

  • Volume: $20\text{L}$.

  • Bladder Material: 112A12 (High-performance NBR variant), optimized for fatigue strength in high-frequency duty cycles.

• SB330-50A1/669U-330A:

  • Volume: $50\text{L}$ High-Capacity.

  • Configuration: 669U specialized bladder. Engineered for large-scale power stations requiring massive instantaneous flow release.

Key Technical Advantages:

• $330 \text{ bar}$ Peak Pressure Security: Forged from seamless steel tubing and compliant with 2026 international pressure vessel fatigue standards, ensuring zero-risk operation under extreme pressure cycles.

• Pro-Grade Bladder Materials (114A9/112A12/669U): Tailored formulas for diverse hydraulic media. From standard mineral oils to eco-friendly synthetic fluids, these bladders ensure long-term elasticity and ultra-low gas permeability.

• Efficient Pulsation Dampening: The rapid-response bladder structure effectively absorbs high-frequency pulsations (above $10\text{Hz}$), protecting sensitive downstream valves and proportional controllers.

• Modular A1 Interface: Standardized fluid port design ensures $100\%$ physical interchangeability with modern 2026 industrial hydraulic stations.

• Anti-Corrosive Coating: High-quality industrial finish protects the shell in humid, dusty, or mildly corrosive environments.

Detailed Technical Specifications:

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

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

• Compatible Mediums: Mineral oils, fire-resistant fluids, water-glycol, and various industrial fluids.

• Temperature Range: Depending on bladder compound (covering $-15^\circ\text{C}$ to $+80^\circ\text{C}$).
