Characteristics of the Uchida AP2D38 hydraulic pump
The Uchida AP2D38 hydraulic pump is a high-performance, variable displacement, dual (tandem) axial piston pump that serves as the main hydraulic pump in mid-range crawler excavators. Its design combines two pumps in one sturdy housing, which allows it to simultaneously power multiple hydraulic circuits for complex operations without loss of power. With its robust design and built-in power control system, the AP2D38 pump ensures efficient use of engine power, stable operation, and durability of the entire hydraulic system of the machine.
