YUKEN PV2R4 Series Single Vane Pump
1. Product Overview
2. Key Features
-
High Operating Pressure & Large Displacement: Capable of withstanding high working pressure while providing larger displacement, meeting the demand for high-power, large-flow hydraulic systems, and ensuring stable output under long-term high-load operation.
-
Low Noise Design: Optimized vane and cam ring structure reduces friction and vibration during operation, achieving low noise levels that meet industrial environmental standards, even with increased displacement.
-
Easy Maintenance: Adopts a cartridge kit design, which allows quick disassembly and replacement of wearing parts (such as vanes, bushings, and seals) without removing the entire pump from the system, greatly reducing maintenance time and cost.
-
Stable Output Flow: Precision machining of internal components ensures uniform flow output, minimizing pressure fluctuations and improving the stability of the entire hydraulic system, suitable for equipment requiring stable large-flow supply.
-
Wide Compatibility: Suitable for various hydraulic fluids, including petroleum-based oils, water-containing hydraulic fluids, and synthetic hydraulic fluids, adapting to different working environments and load requirements.

4. Installation and Usage Notes
-
Before installation, check the pump for damage during transportation, and ensure that all internal components are intact and free of debris, especially for the larger displacement structure.
-
The pump should be mounted on a flat and stable base, and the connection between the pump and the motor should be coaxial to avoid vibration caused by misalignment, which may affect the stability of large-flow output.
-
When connecting the hydraulic pipeline, ensure that the pipeline is clean and free of impurities, and use appropriate sealing materials to prevent oil leakage, especially for high-pressure and large-flow working conditions.
-
Fill the pump with hydraulic fluid before starting to avoid dry friction between internal components, which may cause damage to the precision vane structure.
-
During operation, regularly check the oil temperature, oil level, and noise of the pump. If abnormal phenomena are found, stop the machine immediately for inspection and maintenance to avoid serious damage under high load.
-
Regularly replace the hydraulic fluid and filter element to ensure the cleanliness of the hydraulic system, which can effectively extend the service life of the pump and maintain stable large-flow output.
