Parameters of YUKEN Vane Pumps Models PV2R1-17FQ and PV2R1-17FR

1. Model Interpretation

1.1 Common Code Interpretation (Applicable to Both Models)

• PV2R1: Series code, indicating the PV2R1 series high-pressure vane pump developed by YUKEN, which is specially designed for low-noise operation and high-pressure working conditions, with compact structure and easy maintenance.
• 17: Nominal displacement code, corresponding to a nominal displacement of 17 ml/rev (equivalent to approximately 16.6 cm³/rev in actual measurement).
• F: Mounting type code, indicating flange mounting, which is suitable for most general industrial hydraulic system installation scenarios.

1.2 Model-Specific Code Interpretation

• PV2R1-17FR: The suffix “R” indicates clockwise rotation when viewed from the shaft end, which is a basic model without intelligent control functions, mainly used in conventional hydraulic systems.
• PV2R1-17FQ: The suffix “Q” indicates that the pump is equipped with an intelligent pressure feedback function, which is a compatible upgraded model launched in 2024 to replace PV2R1-17FR, and is more suitable for high-precision control scenarios.

3. Product Features

3.1 Common Features (Applicable to Both Models)

• High Pressure Design: Adopts optimized vane structure and high-strength materials, with a rated working pressure of 21 MPa, suitable for heavy-duty industrial scenarios and ensuring stable performance under high pressure.
• Low Noise Performance: The optimized vane and flow channel design effectively suppresses flow pulsation, with a noise level of ≤70 dB(A) at the rated speed, suitable for noise-sensitive working environments.
• Easy Maintenance: Internal components are assembled as a whole with screws, which is convenient for disassembly, assembly and replacement, reducing maintenance time and costs.
• Long Service Life: Special surface treatment technology is adopted for core components, which improves wear resistance; the service life of the basic model is more than 25,000 hours, and the upgraded model is further optimized.
• Compact Structure: The overall size is small, which is convenient for integration into hydraulic systems with limited installation space.

3.2 Model-Specific Features

• PV2R1-17FR: As a basic model, it has stable performance and high cost performance, and is suitable for conventional hydraulic systems that do not require intelligent control, such as ordinary machine tools and small injection molding machines.
• PV2R1-17FQ: As an upgraded and compatible model, it is equipped with an intelligent pressure feedback function, which can realize real-time monitoring and adjustment of system pressure, and is more suitable for high-precision hydraulic systems such as CNC machine tools.

4. Application Fields

• Common Application Fields: Machine tools (milling machines, grinders, lathes), presses, injection molding machines (especially small and medium-sized vertical injection molding machines), engineering machinery (bending machines, die-casting machines), and other mechanical equipment that requires hydraulic transmission.
• PV2R1-17FR: Mainly used in conventional hydraulic systems with low control precision requirements, such as ordinary lathes, small hydraulic presses, and agricultural machinery.
• PV2R1-17FQ: More suitable for high-precision hydraulic systems that require intelligent pressure control, such as CNC machining centers, precision grinders, and high-end small injection molding machines.

5. Notes

• The pump has high requirements on oil cleanliness; it is recommended to use hydraulic oil that meets NAS 8 level or above, and configure a high-precision filter, and regularly detect the oil cleanliness to avoid wear of precision components caused by impurities.
• For the first operation, the pump should be started with no load for at least 10 minutes, and then the pressure should be gradually increased to ensure stable operation of the pump body and seals.
• When the pump has insufficient flow, the shaft seal and oil suction filter should be checked first to eliminate faults such as oil leakage and blockage.
• The original seal kit of PV2R1-17FR has been discontinued since 2025 and can be replaced with the PV2R1-SK17 seal kit.
• Wearable parts such as valve plates and bearings can be replaced independently; regular inspection and maintenance should be carried out according to working conditions to extend the service life of the pump.
• When using mineral oil, the medium temperature should be controlled within the range of -10°C to 80°C to avoid abnormal operation caused by excessive or insufficient temperature.
