YUKEN PV2R2-41-F-RAA-41 Vane Pump
Parameters of YUKEN Vane Pump Model PV2R2-41-F-RAA-41
1. Model Interpretation
The model PV2R2-41-F-RAA-41 of YUKEN vane pump has a clear and standardized coding rule, and each segment represents specific product characteristics, which is convenient for users to quickly identify and select products:
-
PV2R2: Series code, indicating the single vane pump of PV2R2 series, which is designed for low-noise operation and high-pressure working conditions[4].
-
41: Nominal displacement code, corresponding to a nominal displacement of approximately 41.3 cm³/rev (cubic centimeters per revolution).
-
F: Special seal code, indicating that the pump is equipped with special seals, which is suitable for phosphate ester type fluids (the code can be omitted if not required).
-
R: Shaft rotation direction code, indicating that the shaft rotates clockwise when viewed from the shaft end (the default rotation direction; counterclockwise rotation can be customized with consultation).
-
AA: Port position code, indicating that both the discharge port and the suction port are upward when viewed from the shaft end (the default port position).
-
41: Design number, corresponding to the standard design specification of the PV2R2 series.

3. Product Features
-
Low Noise Performance: Specifically developed for low-noise operation, suitable for equipment requiring high precision and low noise pollution, such as injection molding machines[4].
-
High Reliability: The internal core components are integrated into a cartridge kit, which allows for easy replacement and maintenance, reducing downtime and maintenance costs[4].
-
Wide Fluid Adaptability: Compatible with a variety of hydraulic fluids, including petroleum-based oils, anti-wear oils, and special fluids such as phosphate esters (with corresponding special seals)[4].
-
Stable Operation: The reasonable structural design ensures ultra-low flow pulsation and stable performance, adapting to long-term continuous operation in industrial environments.
4. Application Fields
This model is widely used in various industrial hydraulic systems, including but not limited to: injection molding machines, cutting machinery, plastic machinery, leather machinery, forging machinery, and engineering machinery, meeting the high-pressure and low-noise requirements of different equipment[5].
5. Notes
-
When the operating pressure exceeds 16 MPa (160 kgf/cm²), the shaft speed should be increased to more than 1450 r/min to ensure stable operation.
-
When using phosphate ester type fluids, special F-type seals must be configured, and the maximum shaft speed should not exceed 1200 r/min[4].
-
For low-speed startup, the viscosity of the hydraulic fluid should be controlled within the specified range; refer to the hydraulic fluid specifications for details.
-
Pipe flange kits are available for this model; when ordering, specify the corresponding kit model according to the connection type (threaded, socket welding, butt welding) and design standard (JIS, European, North American).
