What type of lubrication pump is most commonly used in gas turbines?

In gas turbines, a gear lubrication pump is most commonly utilized due to its ability to handle the high flow rates and pressures required for effectively lubricating critical components. Gear pumps operate by using interlocking gears to move oil, providing a constant and reliable flow. This is essential in gas turbines where maintaining proper lubrication is crucial for minimizing wear and tear on moving parts, ensuring longevity and optimal performance.

Gear lubrication pumps are well-suited for the high-speed, high-temperature conditions found in gas turbines, enabling them to circulate lubrication oil efficiently under varying operational conditions. Their design allows for a compact footprint, making them ideal for integrating within the turbine system without occupying excessive space.

While positive displacement pumps also have applications in lubrication systems, gear pumps are specifically favored in gas turbine applications because of their efficiency at delivering the necessary oil flow and pressure characteristics. This makes them a preferred option for ensuring that all bearing surfaces and other critical areas receive sufficient lubrication to operate smoothly.
