NXQ-AB Accumulator Bladder | 40L & 80L | 31.5MPa High Pressure | NBR Rubber Replacement

NXQ-AB Series High-Pressure Bladder Accumulators (40L / 80L)

Product Overview:

The NXQ-AB series is a critical component for large-scale energy storage, pulsation dampening, and fail-safe protection in the heavy-duty hydraulic systems of 2026. This range highlights the $40\text{L}$ and $80\text{L}$ high-capacity models, rated for a robust $31.5 \text{ MPa}$ operating pressure. Equipped with premium NBR (Nitrile Rubber) bladders, these units offer superior gas retention and fatigue resistance—the premier choice for metallurgical machinery, heavy-duty presses, and energy equipment.

Core Model Specifications:

• NXQ-AB-80/31.5-F-Y:

  • Capacity: $80\text{L}$ (Ultra-High Volume).

  • Design: F-Type Flange connection, rated for $31.5 \text{ MPa}$. Engineered for heavy-duty hydraulic stations requiring massive instantaneous power output.

• NXQ-AB-40/31.5-L-Y:

  • Capacity: $40\text{L}$.

  • Design: L-Type Threaded connection, rated for $31.5 \text{ MPa}$. Offers high spatial efficiency, widely used in injection molding machines and large-scale automation lines.

Key Technical Advantages:

• $31.5 \text{ MPa}$ Safety Integrity: Shells are precision-forged from premium seamless alloy steel, complying with 2026 international pressure vessel standards to ensure maximum safety under continuous heavy-load pulsations.

• Premium NBR Rubber Bladder: Crafted from high-nitrile rubber, providing exceptional mineral oil resistance and ultra-low nitrogen permeability. Tested for 1,000,000 cycles to guarantee extended service life.

• Instantaneous Response: The low-inertia bladder structure instantly neutralizes pressure spikes caused by pump switching, significantly reducing circuit noise and protecting sensitive valve groups.

• Standardized Interchangeability: Strictly follows NXQ specifications. Whether using F-Type Flange or L-Type Threaded interfaces, these units provide $100\%$ physical replacement for leading global brands.

• Wide Operating Range: Standard NBR bladders maintain stable physical performance in industrial environments ranging from $-10^\circ\text{C}$ to $+80^\circ\text{C}$.

Detailed Technical Specifications:

• Nominal Volumes: $40 \text{ L} / 80 \text{ L}$.

• Max Working Pressure ($P_{max}$): $31.5 \text{ MPa}$ ($315 \text{ bar}$).

• Bladder Material: High-grade NBR (Nitrile).

• Compatible Mediums: Mineral oils, water-glycol, and non-corrosive industrial liquids.

• Interface Style: F (Flange) or L (Threaded).
