The mass production of MW-class liquid-cooled ultra-fast charging piles must overcome a practical threshold: how to ensure the stable, high-speed circulation of coolant and guarantee stable output at the terminal under terrifying power levels of 1.5MW, 4.5MW, or even higher, while simultaneously minimizing the risk of thermal runaway? Centrifugal pumps can struggle beyond 600KW. What are the alternative solutions?
Since 2018, Suofu has entered the ultra-fast charging pile industry. From kilowatt-class ultra-fast charging (450KW) to megawatt-class ultra-fast charging (4.5MW), it has stably supplied professional-grade magnetic gear pumps in bulk to leading operators, with cumulative shipments exceeding ten thousand units. In long-term, high-intensity commercial operations, Suofu pumps, with their extremely low failure rate and exceptionally long service life, have not only improved heat dissipation efficiency but also significantly reduced the later maintenance costs for operators.
As high-power equipment, MW-class ultra-fast charging imposes far more demanding heat dissipation requirements than ordinary charging devices. Even a single-gun output power of 1 megawatt implies massive heat generation, which must be instantly carried away by high-pressure, high-speed circulating coolant. Achieving efficient circulation within slender, bent, and flow-resistant charging cables makes the following performance indicators of the liquid cooling pump critically important.
✅ Does it provide sufficient differential pressure to overcome flow resistance and ensure the charging pile's full-power output?
✅ Can it handle the viscosity surge of coolants like silicone oil at low temperatures?
✅ Can it achieve zero leakage to avoid damaging the power system?
✅ Can it operate continuously and stably to match the non-stop operation demands of ultra-fast charging stations?
✅ Can it withstand harsh high and low-temperature working environments?
✅ Can it minimize the need for frequent maintenance?
Generally, centrifugal pumps are "high-flow, low-head" devices. Their head drops rapidly as flow increases or medium viscosity rises, leading to reduced cooling efficiency. They struggle to adapt to the ultra-high-power operating conditions of MW-class ultra-fast charging. Moreover, centrifugal pumps typically lack self-priming capability, making system venting and initial filling more troublesome and complicating later maintenance.
With 16 years of deep industry expertise, Suofu's professional-grade magnetic gear pumps have become an excellent solution for high-power ultra-fast charging heat dissipation. Addressing the core cooling needs of charging pile manufacturers, Suofu offers a mature commercial product—the NP Series Magnetic Gear Pumps. Among them, the NP350 has been deployed in MW-class ultra-fast charging terminal applications.
NP350 - MW Ultra-Fast Charging Terminal Liquid Cooling Pump
Fluid Medium: Silicone Oil
Flow Rate: 5-10 LPM
Differential Pressure: 5 bar
Motor: Shielded Motor
Speed Control: 0-5VThrough specialized design, the NP Series from Suofu fully meets the usage requirements of ultra-high-power charging piles with its characteristics of high pressure, wear resistance, wide temperature tolerance, zero leakage, self-priming dry-run capability, and strong stability. In practical use, it offers excellent fluidity, smooth pumping, and fast heat dissipation, quickly removing heat generated by charging modules to ensure the charging pile's full-power output.
Feature | Specific Advantage |
|---|---|
Powerful Performance, Long-lasting Operation | Suofu magnetic gear pumps can deliver a strong differential pressure of 7-8 bar. This means that even with complex flow path designs and long-distance cable delivery, high-speed coolant circulation is guaranteed, enabling "instant heat stripping" even at full load. For gear pumps, 7-8 bar is a low-pressure requirement. At this level, Suofu gear pumps achieve a service life exceeding 50,000 hours. |
Stable Operation Across a Wide Temperature Range | Adapts to temperatures from -55℃ to 90℃ with consistent output performance, solving operational challenges for ultra-fast charging stations in different geographical environments. |
Zero Leakage with Magnetic Drive | Uses magnetic drive technology instead of traditional shaft seals, completely eliminating the risk of dynamic seal wear. In high-value, high-risk equipment like ultra-fast charging piles, "zero leakage" is not just a technical spec but a safety imperative. |
Compatibility with Multiple Media | Suofu gear pumps can handle various coolants like ethylene glycol, silicone oil, and electronic fluorinated liquid, maintaining efficient pumping performance even with high-viscosity media. |
Low Failure Rate | Validated over years in field applications, Suofu gear pumps maintain stable, high performance with minimal after-sales repairs. |
Compact Size, Easy Integration | Suofu gear pumps are micro gear pumps. When paired with a shielded motor, the length is typically around 120mm-150mm; with a high-power motor, it's generally around 280mm-290mm. |
Suofu's entry into the supply chains of leading enterprises in the MW-class ultra-fast charging sector and its adoption for batch applications are primarily based on its rigorously validated product performance, customized service capabilities, excellent production and delivery standards, and extremely low failure rate in practical applications.
For charging pile manufacturers and operators, choosing Suofu means not just selecting a professional liquid cooling pump, but opting for a proven, reliable, and ready-to-deploy mature solution.
