QHX Series Magnetic Pumps: Safety and Efficiency Assurance for Energy Storage Battery Electrolyte Transport

I. Preface: Rapid Growth and Challenges in the Energy Storage Industry

Under the backdrop of “dual carbon goals” and energy transformation, the global energy storage industry is experiencing explosive growth. Various energy storage technologies including lithium batteries, sodium-ion batteries, and flow batteries continue to develop, providing stable energy regulation capabilities for renewable energy sources such as solar and wind power. Whether for residential energy storage systems or large-scale grid frequency regulation devices, the safety and stability of battery systems remain core industry concerns.

In the production and operation phases of energy storage batteries, the transport of electrolytes and coolants represents a critical process. Electrolytes are typically highly corrosive organic solvents or solutions containing acids and alkalis. If transport pumps experience leakage, this not only pollutes the environment but may also trigger serious incidents such as fires or explosions. How to achieve safe, efficient, and long-lasting transport has become one of the core challenges in the energy storage industry chain.

The QHX series magnetic pumps are specifically designed to address these requirements. With their leak-free, corrosion-resistant, temperature-tolerant, and flow-stable characteristics, the QHX series provides safe and reliable fluid transport solutions for the energy storage battery industry.

II. What are QHX Series Magnetic Pumps?

The QHX series magnetic pumps are seal-less, all-plastic chemical pumps that employ magnetic coupling drive technology, eliminating traditional mechanical seals and completely solving the problem of “running, bubbling, dripping, and leaking” in chemical pumps.

Main Parameters:

• Frequency: 50/60 Hz
• Maximum Flow Rate: 1567 L/min
• Maximum Head: 41 m
• Material Options: PPH / PVDF / CFRETTE
• Liquid Temperature Range:
  • PPH: 0 ~ 80°C
  • PVDF: 0 ~ 90°C
  • CFRETTE: -10 ~ 120°C

These performance specifications mean that QHX magnetic pumps are suitable not only for traditional acid-alkali transport but can also maintain stable operation in complex environments involving high-temperature electrolytes, organic solvents, and coolant circulation.

III. Why the Energy Storage Battery Industry Needs Magnetic Pumps

1. Complexity and Hazards of Electrolytes

Electrolytes in energy storage batteries are diverse, including:

• Lithium batteries: Organic solvents containing lithium salts (such as LiPF₆) with carbonate compounds – flammable and highly volatile
• Sodium-ion batteries: Sodium salt solutions with strong corrosivity
• Flow batteries (such as vanadium flow batteries): Acidic solutions containing metal ions that severely corrode pump bodies

These liquids are characterized by:

• Strong corrosivity → Corrodes metal pump bodies, shortening service life
• High volatility/flammability → May cause fires if leaked
• Temperature sensitivity → Battery cycling requires precise temperature control; pump bodies must adapt to cooling and heating conditions

2. Problems with Traditional Pumps

• Mechanical seal failure → Electrolyte leakage causing safety hazards
• Pump body corrosion → Short service life and frequent shutdowns
• Unstable flow rates → Affects battery performance and consistency

3. Why Magnetic Pumps are the Superior Choice

• Leak-free: Magnetic coupling transmission eliminates leakage hazards
• Corrosion-resistant: All-plastic construction adapts to acids, alkalis, and organic solvents
• Wide temperature tolerance: -10 ~ 120°C meets battery cooling and circulation requirements
• High reliability: Suitable for 24-hour continuous operation

IV. Problems QHX Magnetic Pumps Can Solve

1. Safety Assurance: Leak-Free Design

Once energy storage battery electrolytes leak, they not only pollute the environment but may also react with moisture in the air, producing toxic gases or even causing combustion.

• QHX magnetic pumps employ seal-less design → Fundamentally eliminates leakage risks
• Improves energy storage system safety levels, meeting international safety standards (such as UL, IEC)

2. Corrosion Resistance: Compatible with Different Electrolytes

• PPH: Suitable for general acid-alkali liquids, such as sodium battery preprocessing
• PVDF: Suitable for lithium battery processes involving hydrofluoric acid or highly corrosive organic solvents
• CFRETTE: Suitable for high-temperature electrolytes or flow battery acidic systems

This material diversity allows QHX pumps to cover virtually all liquid transport requirements across the energy storage battery industry chain.

3. Stable Operation: Enhanced Battery Consistency

The stability of electrolyte transport directly affects battery production consistency:

• Stable flow rates → Ensures uniform electrode reactions
• Precise temperature control → Guarantees battery performance and cycle life
• Continuous operation capability → Meets large-scale production line requirements

4. Reduced Maintenance Costs

• Traditional pumps require frequent seal replacement with high shutdown costs
• QHX magnetic pumps are maintenance-free with longer service life
• Overall operating costs reduced by over 30%

5. Environmental Compliance

• Prevents leakage pollution → Complies with ISO14001, REACH, and other environmental requirements
• Supports sustainable development of the energy storage industry chain

V. Application Case Studies

Case 1: Lithium Battery Electrolyte Injection Process

• Problem: Metal pumps corrode easily; post-leakage electrolyte volatility creates explosion risks
• Solution: QHX PVDF magnetic pumps → Achieve leak-free transport, ensuring production safety

Case 2: Vanadium Flow Battery Electrolyte Circulation

• Problem: Sulfuric acid medium highly corrosive; traditional pumps have short service life
