Fuel Pump
Description
The 463B is an aircraft electrically driven centrifugal fuel pump designed to create positive fuel pressure at the inlet of the main engine fuel pump and to increase the altitude capability of the aircraft fuel system.
Within the fuel supply circuit, the pump operates as a booster unit, ensuring stable fuel delivery under conditions of reduced inlet pressure, high-altitude operation, and variable engine demand, preventing fuel starvation and cavitation.
The pump is installed in aircraft fuel systems of helicopters and other aircraft, including the Mi-8, Mi-17, Mi-171, and Mi-172 family, and is used to improve fuel system reliability and engine performance.
The product is also known under alternative designations 463B, which refer to the same product type.
