Astralcooler Pump-reservoir Combo Unit

Product Function

• Sufficient coolant reserve prevents low liquid levels from evaporation or slow leaks, guaranteeing the pump always has liquid to draw from.

Featured Design

• Large Coolant Capacity:
  
  • Can hold 200–350ml of coolant, meeting the reserve requirements of high-power systems such as dual-CPU and quad-GPU setups, reducing the need for frequent refilling.
    
• Anti‑Vortex Structure:
  
  • The built-in buffer chamber and anti-vortex structure effectively dampen pressure surges caused by temperature changes or pump speed fluctuations, prevent joint leakage, and ensure more uniform flow distribution to each branch in parallel waterway configurations (e.g., dual-CPU, quad-GPU systems).
    
• Strong Power Pump:
  
  • The integrated high-head water pump provides a 15‑meter head, 1400 L/h flow rate, and sine‑wave PWM control (via 4D connector), delivering strong driving force for rapid coolant circulation and hotspot elimination even with multiple water blocks and dense GPU arrays.

Premium Material

• PVC Composite Material:
  
  • Excellent impact and pressure resistance; resists cracking and deformation. Low chemical reactivity prevents bacterial or algal growth and minimizes impurity deposition. Compatible with the vast majority of water cooling solutions on the market.
    
• Ceramic Shaft Core:
  
  • High hardness and wear resistance ensure long-term reliability, with excellent chemical inertness against coolant corrosion.
    
• Acrylic Transparent Window:
  
  • Allows visual inspection of liquid level and air bubbles.
