Customized designs can be developed according to user requirements, including product appearance, materials, voltage, flow rate, pressure, and interface type.
- For passenger cars and light-duty vehicles, use an in-tank brushless fuel pump that provides low noise and a long service life.
- For heavy-duty trucks, construction equipment, and agricultural machinery, select an external in-line pump that offers easy maintenance and high durability.
- For marine engines and generator sets, choose a high-pressure pump designed for continuous operation to ensure stable fuel delivery.
- For diesel engines, select a pump with integrated fuel preheating or cold-weather protection to prevent fuel gelling at low temperatures.
- For gasoline, methanol, or alternative fuels, confirm that the materials are corrosion-resistant and compatible with the selected fuel.
- For standard fuel transfer needs, a brushed pump provides a reliable and cost-efficient solution.
- For applications requiring high reliability and intelligent control, a brushless pump supports CAN, LIN, and ECU interfaces, allowing integration with smart control systems.
