fuel pump
Description
ECN-91S is an aircraft electrically driven centrifugal fuel pump designed for fuel transfer from aircraft fuel tanks to the engine or between fuel tanks. The pump is used in aircraft fuel systems to ensure stable fuel delivery under various operating conditions.
The ECN-91S pump is of centrifugal design and is driven by a DC electric motor. Fuel is transferred by centrifugal force from the center of the impeller to the periphery and discharged through the outlet port, providing continuous and stable flow. The pump is designed for operation with aviation fuels and is suitable for use in helicopter fuel systems.
ECN-91S is widely applied on helicopters of the Mi-8 / Mi-17 / Mi-171 / Mi-172 family and is installed as part of the onboard fuel supply system. The pump ensures reliable fuel delivery during normal operation, engine start, and fuel transfer processes.
The pump operates from a 27 V DC onboard electrical system and is designed for operation within extended ambient and fuel temperature ranges. Its construction supports reliable operation at high altitudes and under demanding environmental conditions typical for aviation use.
