YUKEN A145 series variable piston pump specifications are as follows：
1. Basic parameters
Type: Variable piston pump (axial plunger design)
Displacement range: 15.8 mL/rev to 145 mL/rev (specific models such as A145-LR01BS-60 have a displacement of 145 mL/rev)
Rated pressure：
Conventional model: 25 MPa (some high-pressure models can reach 70 MPa, such as A145-FR01KS-60)
Maximum working pressure: 28 MPa (long-term operation is recommended not to exceed the rated pressure)
Speed range：
Standard speed: 1800 r/min
Scope of application: 1000-3000 r/min (need to avoid overspeed operation)
