Product Overview
The UCHIDA HYDRAULICS AP2D25LV1RS7-901-1 is a high-performance axial piston pump engineered by Uchida Hydraulics (Uchida Rexroth / UCHIDA Hydraulics Co., Ltd.), a globally recognized manufacturer of compact, high-efficiency hydraulic components. This variable displacement axial piston pump operates on the swashplate principle, where a precision-ground swashplate angle controls the stroke of pistons reciprocating within a cylinder barrel, thereby delivering infinitely variable flow output proportional to the swashplate inclination. The AP2D25 series is specifically designed for compact mobile and industrial hydraulic systems requiring high pressure capability, low noise emission, and precise displacement control. The “LV” designation indicates a specific control configuration (load-sensing / variable displacement control), while the “RS7-901-1” suffix denotes the factory rotation, mounting, and porting variant. This pump serves as the primary pressure and flow source in closed or open hydraulic circuits, converting mechanical input power from an electric motor or combustion engine into controlled hydraulic energy for downstream actuators, cylinders, and motors.
