NXQ Bladder Accumulator | 0.63L-100L Capacity | 10-31.5MPa High Pressure | NXQ-A Series

NXQ Series High-Pressure Bladder Hydraulic Accumulators

Product Overview:

The NXQ series represents high-performance standard bladder accumulators engineered for the industrial automation, construction machinery, and power sectors of 2026. By utilizing a nitrogen-filled bladder within a pressure-resistant shell, it performs vital functions such as energy storage, pulsation dampening, and leakage compensation. This page covers the complete range from micro $0.63\text{L}$ to heavy-duty $100\text{L}$ models, with pressure ratings spanning $10\text{MPa}, 20\text{MPa}, \text{to } 31.5\text{MPa}$.

Core Model Capacities:

• Small Capacity Range: NXQ-A-0.63/1/1.6/2.5/4L (Ideal for precision machine tools and compact power units).

• Medium Capacity Range: NXQ-A-6.3/10/16/25/40L (Highly versatile, widely used in injection molding and metallurgical equipment).

• Large Capacity Range: NXQ-A-63/100L (Providing robust auxiliary power and emergency energy reserves).

Key Technical Advantages:

• $31.5 \text{ MPa}$ High-Pressure Capability: Shells are forged from premium seamless steel tubing and undergo rigorous non-destructive testing to ensure burst safety under intensive 2026 industrial operations.

• Superior Gas-Tight Bladders: Utilizing bladders made from import-grade NBR or Viton, offering ultra-low gas permeability and exceptional fatigue resistance during frequent cycling.

• Instantaneous Power Response: Due to minimal bladder inertia, the NXQ series responds instantly to pressure fluctuations, effectively absorbing pump flow ripples to reduce system noise and protect piping.

• Wide Temperature Adaptability: Optimized thermal exchange design maintains stable performance within $-10^\circ\text{C}$ to $+70^\circ\text{C}$ (standard models).

• Standardized Interchangeability: Strictly follows the NXQ Type A standard, ensuring precise interface dimensions for direct replacement of mainstream brands.

Detailed Technical Specifications:

• Volume Range: $0.63, 1, 1.6, 2.5, 4, 6.3, 10, 16, 25, 40, 63, 100 \text{ Liters}$.

• Nominal Pressure: $10 \text{ MPa}, 20 \text{ MPa}, 31.5 \text{ MPa}$.

• Compatible Mediums: Mineral oil, phosphate ester, and water-glycol.

• Connection Type: Threaded / Flanged connections.
