A10 series :  displacement 10.0cm3/rev
A16 series :  displacement 15.8cm3/rev
A22 series :  displacement 22.2cm3/rev
A37 series :  displacement 36.9cm3/rev
A56 series :  displacement 56.2cm3/rev
A70 series :  displacement 70.0cm3/rev
A90 series :  displacement 91.0cm3/rev
A145 series :  displacement 145cm3/rev

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)
