YUKEN AR16-FR01B-20 Series Variable Displacement Piston Pump – Models & Parameters

1. Model Description (YUKEN AR16-FR01B-20)

The model code of YUKEN AR16-FR01B-20 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:

• AR16: Basic model, indicating the nominal displacement series. The AR16 series is a small-displacement variable piston pump, specifically designed for low-to-medium pressure hydraulic working conditions. It features a compact structure, light weight and reliable operation, with a nominal displacement matching the 16 series specification. This series is widely applied in small hydraulic systems that require stable performance and space-saving installation.
• FR: Combined code of mounting type and rotation direction. The first letter “F” stands for flange mounting, a common installation method in industrial hydraulic systems that ensures a stable connection between the pump and the power unit, reduces vibration during operation, and guarantees long-term reliable service; the second letter “R” indicates clockwise rotation (viewed from the shaft end), which is the standard rotation direction for most matching hydraulic equipment, facilitating seamless matching with motors and other power components.
• 01: Control type, representing manual proportional control. It allows manual adjustment of the pump’s displacement according to the actual working requirements of the system, with simple operation and high control accuracy. This control type is particularly suitable for occasions with stable working conditions and no frequent parameter adjustment needs.
• B: Additional configuration code, indicating a built-in relief valve. The integrated relief valve serves as a key safety component, which can effectively protect the pump body and the entire hydraulic system from damage caused by overpressure, significantly improving the safety and stability of the system during operation.
• 20: Installation flange standard, complying with relevant international industrial standards. This standardization design facilitates the interchangeability of the pump in different equipment, simplifies later maintenance and replacement procedures, and reduces maintenance costs.

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 a good energy-saving effect. It is especially suitable for small hydraulic systems with limited installation space and stable working conditions.

2. The nominal pressure of the AR16 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 fully meet the needs of most light-to-medium load working conditions.

3. The “B” configuration (built-in relief valve) in the model is a standard safety design, which can effectively prevent system overpressure and protect the pump and related components. 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 the stable and efficient operation of the hydraulic system.
