Series index
Five catalogue-backed product families
Each family serves a different displacement, pressure and control requirement. The values below are category-level guidance from the supplied Yuken catalogues. Final selection must use the complete model designation.
A Series
Variable displacement piston pumps available across eight displacement sizes and multiple catalogue-listed control types.
- A10 to A145
- 10.0 to 145.0 cm³/rev.
- Rated pressure varies by model group
A3H Series
High-pressure variable displacement piston pumps with a broad delivery range and pressure-compensator, constant-power and load-sensing control families.
- A3H16 to A3H180
- 16.3 to 180.7 cm³/rev.
- Maximum operating pressure stated as 350 kgf/cm²
A3HG Series
High-pressure pumps based on the A3H family, with ISO and SAE-compatible configurations and through drive supplied as standard.
