In the field of electric vehicle fast charging (ultra-fast charging or supercharging), the efficiency of the cooling system directly impacts charging speed and equipment lifespan. As a core component of the cooling system, the selection of the pump is crucial. This article explores how to choose the appropriate pump component in the ultra-fast charging field, with a focus on the advantages of Suofu micro gear pumps compared to other pump types.
1. Higher Operational Efficiency and Lower Energy Consumption in Low-Flow High-Pressure and High-Viscosity Applications
Suofu micro gear pumps employ advanced gear meshing technology. During operation, the tight fit between the gears significantly reduces fluid leakage, resulting in high volumetric efficiency. This characteristic enables them to provide stable and precise flow output even under low-speed operating conditions.
Centrifugal pumps perform well in high-flow demand scenarios, leveraging their high-speed rotating impellers and large flow channels to rapidly move large volumes of fluid. However, their efficiency drops significantly in low-flow conditions. Furthermore, when handling high-viscosity fluids, the viscous resistance severely hampers the normal operation of the impeller, leading to a notable decrease in overall pump efficiency and a substantial increase in energy consumption. Compared to Suofu micro gear pumps, centrifugal pumps exhibit a clear disadvantage in terms of energy consumption in these scenarios.
2. Superior Coolant Versatility
Thanks to its unique gear structure, sealing design, and the use of special materials for pump parts, the Suofu micro gear pump can easily handle the delivery challenges of various coolants with different chemical properties and high-viscosity fluids. It operates stably within a viscosity range of 0.2~10,000 cps and with different media such as ethylene glycol, silicone oil, and electronic fluorinated liquid, ensuring precise material delivery. Its precise flow control capability also makes it excel in applications with extremely high flow accuracy requirements, such as laboratory equipment and metering devices.
In ultra-fast charging applications, centrifugal pumps can only be used in systems with low-viscosity ethylene glycol as the coolant. If the customer's cable length exceeds 4 meters and the coolant is changed to silicone oil, centrifugal pumps cannot function properly, especially under low-temperature, high-viscosity conditions.
Comparison Item | Suofu Micro Gear Pump | Centrifugal Pump |
|---|---|---|
Efficiency & Energy Consumption | High volumetric efficiency, provides stable flow at low speeds, lower energy consumption. | High efficiency for high-flow demands, but efficiency drops significantly in low-flow or high-viscosity fluids; relatively higher energy consumption. |
Applicability | Has self-priming capability, can operate with gas-liquid mixtures, suitable for high-viscosity fluids and applications requiring precise flow control. | No self-priming capability, cannot handle gas-liquid mixtures. Only suitable for transporting large flow, low-viscosity, low-head fluids. |
Applicable Fluids | Universal for ethylene glycol, silicone oil, electronic fluorinated liquid. | Low-viscosity ethylene glycol only. |
Advantages of Suofu Micro Gear Pumps vs. Centrifugal Pumps in Ultra-Fast Charging Applications
Gear Pumps Have Superior Wear Resistance Compared to Vane Pumps
Suofu gear pumps feature lower wear and longer life compared to vane pumps and other similar gear pumps, owing to the use of advanced wear-resistant materials and specially designed gear profiles. Suofu gear pumps possess a patented low-sliding gear profile, which significantly reduces sliding friction during operation compared to conventional gear profiles.
Particularly in contrast to vane pumps, the gear tips in Suofu pumps do not contact the pump body, resulting in a manifold reduction in sliding friction between moving parts during operation.

Technical Advantage | Patented gear profile, low wear, long life. | Full-area, continuous friction, high wear, short lifespan. |
Advantages of Suofu Micro Gear Pumps vs. Vane Pumps in Ultra-Fast Charging Applications
During operation, the vanes in a vane pump experience full-area friction on both sides within the vane slots, and the vane tips are in continuous contact with the pump body. Combined with the fact that the vane material in most commercially available vane pumps is carbon graphite, this leads to significant wear, releasing a large amount of graphite particles into the downstream system piping, degrading its performance.

Comparison photos of the liquid after the experiment are shown below. The water from the vane pump turned black due to graphite powder shedding, while the water delivered by the Suofu gear pump remained clear.
