What action is performed by the lube and scavenging pump?

The lube and scavenging pump is crucial for ensuring the proper functioning of gas turbine systems. Its primary role is to supply oil to lubricate various components within the system. This lubrication is essential for reducing friction and wear between moving parts, thus prolonging their lifespan and enhancing overall efficiency.

Without adequate lubrication, components such as bearings, gears, and other critical elements would experience increased wear and potential failure, leading to reduced performance and possibly catastrophic damage. The scavenging aspect of the pump aids in collecting the oil after it has circulated through the system, returning it to the sump for recirculation, which further reinforces the essential nature of this pump in maintaining the health of the gas turbine.

This function directly supports the overall operational integrity of the turbine, making it a key component in the lubrication system.
