Which type of fuel pump is typically used for transferring fuel between tanks?

The booster pump is specifically designed for transferring fuel between tanks due to its ability to efficiently handle higher fuel flow rates and lower pressure conditions. It is commonly used in aircraft fuel systems to move fuel quickly and effectively, ensuring that each tank maintains optimal levels and that the system operates smoothly.

This type of pump enhances the overall fuel system performance by providing a consistent flow of fuel, particularly in situations where gravity alone may not be sufficient for transferring fuel from one tank to another. It is often used in conjunction with other pump types in the fuel system to ensure reliable operation and maintain necessary pressure levels.

In contrast, centrifugal pumps are typically used for moving larger volumes of fuel but may not be as effective for tank-to-tank transfers because they can struggle with maintaining the required suction under low-pressure conditions. A pump with a variable speed drive is designed to adjust the flow rate based on system demands but does not specifically cater to the tank transfer function. Lastly, a sliding vane pump provides reliable performance for certain applications but may not be the optimized choice for effectively transferring fuel between aircraft tanks compared to the dedicated functionality offered by a booster pump.
