List of spare parts

The hydraulic pump operates based on the principle of positive displacement, where mechanical force (from the engine) drives the pump to create fluid flow. The key steps in its operation include:

• Suction Phase: As the pump’s internal mechanism (e.g., gears, pistons, or vanes) rotates, it creates a vacuum that draws hydraulic fluid from the reservoir.

• Compression Phase: The trapped fluid is pressurized as the pump’s moving parts reduce the chamber volume, forcing the fluid into the hydraulic system.

• Discharge Phase: The high-pressure fluid is delivered to control valves, cylinders, or motors to perform mechanical work.

Common types of hydraulic pumps used in excavators include:

• Gear Pumps – Simple, cost-effective, and suitable for medium-pressure applications.

• Piston Pumps – High efficiency and pressure capability, ideal for heavy-duty excavators.

• Vane Pumps – Provide smooth flow with moderate pressure, often used in compact excavators.
