Komatsu Excavator Parts Main Pump 200-5G

The term "main pump" in the context of an excavator typically refers to the primary hydraulic pump responsible for generating high-pressure hydraulic fluid to power various hydraulic components and functions within the machine. Here are key points related to the main pump in an excavator:

1. Function: The main pump is a critical component of the excavator's hydraulic system. It pressurizes hydraulic fluid to provide the necessary force for operating functions such as lifting, digging, and moving the machine.

2. Hydraulic System Control: Excavators use hydraulic systems to control the movement of the boom, arm, bucket, and other attachments. The main pump is responsible for supplying pressurized hydraulic fluid to these components.

3. Variable Displacement: Many modern excavators are equipped with variable displacement pumps, allowing the main pump to adjust the flow of hydraulic fluid based on the load and requirements of the machine.

4. Piston Pump or Gear Pump: The main pump is typically either a piston pump or a gear pump. Piston pumps are more common in larger excavators due to their higher efficiency, while gear pumps may be used in smaller machines.

5. Flow and Pressure: The main pump generates a specific flow rate and pressure of hydraulic fluid, which is crucial for the proper functioning of hydraulic components like cylinders, motors, and valves.
