🛠️ Product Description

Gear Pump is a hydraulic pump used in the Volvo EC480 excavator to generate flow and pressure by using intermeshing gears. It is commonly used for pilot oil supply, lubrication circuits, and auxiliary hydraulic functions.

⚙️ Function / Working

• Consists of two rotating gears inside a housing
• As gears rotate, they trap and move hydraulic oil from inlet to outlet
• Produces a steady and continuous oil flow
• Supplies oil to:
