What type of fuel boost pump is designed to separate air and vapor from the fuel?

The centrifugal type pump is specifically designed to separate air and vapor from fuel. This ability stems from its operational characteristics, where the impeller creates a low-pressure zone that helps to draw fuel into the pump while pushing air and vapor toward the discharge side. This action allows for effective separation of unwanted gases, ensuring that the fuel delivered to the engine is pure and at the correct pressure. The centrifugal design allows the pump to maintain a constant flow and pressure, which is crucial for optimal aircraft fuel system performance.

This type of pump is often used in fuel systems because of its efficiency in handling large volumes of fuel while minimizing the risk of vapor locks and maintaining a reliable supply of liquid fuel to the engine.
