Excavator Hydraulic Pump Basics
Pump Function
You rely on the excavator hydraulic pump to power your machine’s most important movements. This pump pushes oil through the hydraulic lines, making sure each part gets the energy it needs. When you move the controls, the pump sends pressurized oil to the cylinders. This action lets you lift, lower, or swing the arm and bucket. Without a steady flow of oil, your excavator cannot work properly.
The hydraulic pump keeps oil moving through the system.
It controls the movement of the arm and bucket by sending oil to the right cylinders.
The pump provides a constant flow of pressurized oil, which is vital for all working parts.
Tip: Always check the oil level and pressure before starting work. This simple step helps you avoid damage and keeps your machine running smoothly.
