YUKEN A3H16-FR01KK-10 Variable Displacement Piston Pumps
YUKEN A3H16-FR01KK-10 Series Variable Displacement Piston Pump – Models & Parameters
1. Model Description (YUKEN A3H16-FR01KK-10)
The model code of YUKEN A3H16-FR01KK-10 series variable displacement piston pump follows YUKEN’s standard coding rules, and each segment represents specific technical characteristics, which are closely related to the pump’s structure, installation and working performance, as detailed below:
- A3H16: Basic model, indicating the nominal displacement series. The A3H16 series is a small-displacement variable piston pump, specially designed for low-to-medium pressure hydraulic working conditions, with compact structure, light weight and reliable performance, and its nominal displacement matches the 16 series specification, which is widely used in small hydraulic systems.
- FR: Combined code of mounting type and rotation direction. The first letter “F” represents flange mounting, a common installation method in industrial hydraulic systems that ensures stable connection between the pump and the power unit, reduces vibration during operation, and guarantees reliable long-term operation; the second letter “R” represents clockwise rotation (viewed from the shaft end), the standard rotation direction for most matching hydraulic equipment, facilitating matching with motors and other power components.
- 01: Control type, indicating manual proportional control. It can manually adjust the pump’s displacement according to the actual working needs of the system, with simple operation and high control accuracy, suitable for occasions with stable working conditions and no frequent parameter adjustment requirements.
- KK: Double additional configuration code, indicating enhanced sealing and material adaptation design. The double “K” configuration strengthens the sealing performance of the pump, adopts wear-resistant and corrosion-resistant materials, enables the pump to adapt to more complex working environments (such as medium-temperature, medium-humidity or mild corrosive working conditions), and effectively extends the service life of the pump compared with a single “K” configuration.
- 10: Installation flange standard, complying with relevant international industrial standard specifications, which is convenient for the interchangeability of the pump in different equipment and facilitates later maintenance and replacement.

3. Supplementary Notes
1. The displacement of the variable displacement piston pump can be continuously adjusted within a certain range according to the system demand, which is suitable for occasions requiring flexible adjustment of flow and pressure, and has good energy-saving effect, especially suitable for small hydraulic systems with limited installation space.
2. The nominal pressure of the A3H16 series is 160-210 bar, which is suitable for low-to-medium pressure hydraulic systems such as small engineering machinery, precision hydraulic machine tools, light industrial equipment and automatic control equipment, and can meet the needs of most light-to-medium load working conditions.
3. The “KK” enhanced configuration in the model is designed for complex working environments, which can effectively improve the pump’s resistance to wear and corrosion. If special customization is needed (such as high-temperature resistant seals, special flange standards, etc.), please consult the manufacturer for details.
4. For detailed installation dimensions, maintenance methods, performance test data and other parameters, refer to the official technical manual of YUKEN. Regular maintenance and proper use can effectively extend the service life of the pump and ensure stable operation of the hydraulic system.
