The hydraulic pump is a critical component in excavators, responsible for converting mechanical energy into hydraulic energy. It supplies high-pressure hydraulic oil to various actuators (such as hydraulic cylinders and motors), enabling smooth and efficient operation of the excavator. High-quality hydraulic pumps ensure durability, energy efficiency, and precise control, making them essential for construction, mining, and other heavy-duty applications.

Engineered for extreme durability, these pumps feature hardened alloy pistons and copper-plated rotors to withstand high-frequency excavator shocks. Integrated pressure compensation and load-sensing controls adapt to dynamic working conditions. Beyond power transmission, they maintain stable pressure via closed-loop feedback, enabling smooth coordination of lifting, slewing, and digging--even in dusty or extreme-temperature environments.

Modern excavators predominantly use swashplate-type axial piston pumps. By electronically adjusting the swashplate angle via proportional valves, the piston stroke and pump displacement are precisely controlled. This enables instant response to operator commands: reducing flow for energy savings under light loads, while boosting pressure for heavy digging. Crucially, it balances power and efficiency, minimizing heat generation and extending equipment lifespan.
