Characteristics of the Uchida AP2D25 hydraulic pump
The Uchida AP2D25 hydraulic pump is a powerful dual (tandem) axial piston pump with variable displacement, which is the heart of the hydraulic system in midi excavators and other mobile equipment. Its design combines two independent pumps in one robust housing, which allows you to simultaneously power multiple hydraulic circuits, ensuring high performance and smooth operation. Thanks to the built-in power control system, the AP2D25 pump optimizes the load on the engine, which contributes to fuel economy and increases the overall reliability of the machine.
