Characteristics of the Uchida AP2D12 hydraulic pump
The Uchida AP2D12 hydraulic pump is a compact, dual (tandem) axial piston pump with variable displacement, designed primarily for use as a main pump in mini excavators and other compact construction equipment. Its design combines two piston pumps in a single housing, which allows it to efficiently and independently power the machine's different hydraulic circuits (e.g., undercarriage and work equipment). It is often also equipped with a third, smaller gear pump to power the control circuits.
Technical characteristics of the Uchida AP2D12 hydraulic pump:
- Type: Axial piston pump, double (tandem), with variable displacement.
