Characteristics of the Uchida AP2D18 hydraulic pump
The Uchida AP2D18 hydraulic pump is a high-performance dual (tandem) axial piston pump with variable displacement, which serves as the main power unit of hydraulic systems in mini excavators and other mid-range mobile equipment. Its design combines two pumps in one housing, which allows you to effectively power several hydraulic circuits simultaneously, ensuring high speed and smooth operation. Thanks to its reliable design and built-in power control system, the AP2D18 pump ensures optimal use of engine power, durability and stable operation of the machine under load.
Technical characteristics of the Uchida AP2D18 hydraulic pump:
- Type: Axial piston pump, double (tandem), with variable displacement
- Design: Swash plate pump. Often equipped with a third gear pump for control circuits (pilot line)
- Displacement (piston part): 2 x 18 cm³/rev
- Nominal working pressure: 20.6 MPa (210 kgf/cm² or 206 bar)
- Maximum pressure: up to 25 MPa (250 bar)
- Maximum rotation speed: ~2400 - 2600 rpm
- Performance (Flow): 2 x ~43 l/min
- Direction of rotation: Right (clockwise)
- Weight: Approximately 40 - 45 kg
- Application: Main hydraulic pump for 4-5 ton mini excavators
Hydraulic pump cross number: 2293229, 229-3229, 31MH-10010, 263-1867
