Pump Control Unit

A Pump Control Unit (PCU) is a component of the Engine Fuel System in aircraft and missile prime movers. It falls under the supply class of Engine Fuel System Components and is categorized within the supply group of Engine Accessories.

The PCU is responsible for controlling the operation of fuel pumps within the engine fuel system. It regulates the flow of fuel to the engine, ensuring that the correct amount of fuel is delivered at the right pressure and at the appropriate times during the engine's operation.

The PCU typically consists of various sensors, valves, and electronic control units that work together to monitor and adjust the fuel flow. It receives input from the engine's control system and uses this information to regulate the fuel pumps accordingly.

By maintaining precise control over the fuel flow, the PCU helps optimize engine performance, fuel efficiency, and overall reliability. It plays a crucial role in ensuring the proper functioning of the engine fuel system, which is essential for the safe and efficient operation of aircraft and missile prime movers.
