Characteristics of the Uchida AP2D28 hydraulic pump
The Uchida AP2D28 hydraulic pump is a powerful dual (tandem) axial piston pump with variable displacement, which is the central element of the hydraulic system in midi excavators and other heavy mobile equipment. Its design combines two independent pumps in one housing, which allows you to simultaneously and without loss of performance power supply of different circuits, for example, the chassis and working equipment. Thanks to its high reliability and integrated power control system, the AP2D28 pump ensures efficient use of engine power and stable, long-term operation of the machine under high loads.
Technical characteristics of the Uchida AP2D28 hydraulic pump:
- Type: Axial piston pump, double (tandem), with variable displacement
- Design: Swash plate pump. Usually equipped with a third gear pump for the control circuits (pilot line)
- Displacement (piston part): 2 x 28 cm³/rev
- Nominal working pressure: 24.5 - 27.5 MPa (250 - 280 bar)
- Maximum pressure: up to 31.4 MPa (320 bar)
- Maximum rotation speed: ~2200 - 2400 rpm
- Performance (Flow): 2 x ~62-67 l/min
- Direction of rotation: Right (clockwise)
- Weight: Approximately 60 - 65 kg
- Application: Main hydraulic pump for 6-9 ton midi excavators
