Doosan DH258 K3V112DTP-HN1F Excavator Hydraulic Pump

Belparts excavator DH258 K3V112DTP-HN1F hydraulic pump for Doosan K3V112dtp Fix pressure

The excavator hydraulic pump is the "heart" of the excavator's hydraulic system, and its performance directly determines the operating efficiency and stability of the excavator. Its core principle is to change the volume of the sealed working chamber through mechanical movement, thereby realizing the suction and discharge of liquid, converting the mechanical energy of the engine into hydraulic energy, and providing a power source for the entire hydraulic system.

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.
