NXQA Bladder Accumulator | 32L & 2.5L | 31.5MPa High Pressure | NBR Rubber Bladder

NXQA Series High-Pressure Bladder Accumulators & NBR Bladders

Product Overview:

The NXQA series stands as a critical component in 2026 hydraulic systems for energy storage, pulsation dampening, and emergency power. This range features capacities from the compact $2.5\text{L}$ to the high-capacity $32\text{L}$ models, with a robust operating pressure of $31.5 \text{ MPa}$. Equipped with premium NBR (Nitrile Rubber) bladders, these units offer exceptional gas tightness and wear resistance for high-pressure pump stations and automated machinery.

Core Model Specifications:

• NXQA-32L/31.5MPA-L-Y:

  • Volume: $32\text{L}$.

  • Specs: 219 Series standard diameter, rated at $31.5 \text{ MPa}$.

  • Application: Ideal for large industrial presses and metallurgical equipment requiring significant pressure compensation.

• NXQA-2.5/31.5-L-Y:

  • Volume: $2.5\text{L}$.

  • Specs: Compact high-pressure design, rated at $31.5 \text{ MPa}$.

  • Application: Specifically engineered for small hydraulic units with space constraints or high-frequency pulse elimination.

Key Technical Advantages:

• $31.5 \text{ MPa}$ Industrial Pressure Grade: Shells are forged from premium seamless steel tubing, complying with 2026 international pressure vessel standards to ensure burst safety under extreme cycles.

• High-Performance NBR Rubber Bladder: Crafted from high-nitrile NBR (Nitrile Butadiene Rubber), providing superior mineral oil resistance, excellent elasticity, and ultra-low nitrogen permeability to minimize pre-charge maintenance.

• 219 Series Standardized Fit: Strictly adheres to international dimension standards, ensuring $100\%$ physical interchangeability with NXQA shells from major global brands.

• Instantaneous Response: The low-inertia bladder structure allows for the immediate release of stored energy, effectively dampening vibrations and noise within the hydraulic circuit.

• Service-Friendly Design: Optimized gas valve and fluid port configurations make on-site nitrogen charging and bladder replacement rapid and straightforward.

Detailed Technical Specifications:

• Nominal Volume: $2.5 \text{ L} / 32 \text{ L}$.

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

• Bladder Material: High-grade NBR (Viton options available).

• Compatible Mediums: Mineral oils, water-glycol, and emulsions.
