Characteristics of the Uchida AP2D21 hydraulic pump
The Uchida AP2D21 hydraulic pump is a powerful dual (tandem) axial piston pump with variable displacement, which acts as the main power unit in the hydraulic systems of mini excavators and other mobile equipment. Its design combines two independent pumps in one housing, ensuring high performance and the ability to simultaneously perform several operations without loss of power. Thanks to its reliable design and control system, the AP2D21 pump effectively uses engine power, ensuring stable operation and durability of the entire hydraulic system.
