Description

YUKEN PV2R3 Series Single Vane Pump

1. Product Overview

The YUKEN PV2R3 series single vane pump is a high-reliability, high-efficiency hydraulic component designed for medium to high-pressure industrial applications. With its compact structure, low noise emission, and stable performance, it is widely used in hydraulic systems of injection molding machines, metalworking machinery, plastic machinery, and other heavy-duty equipment. The pump adopts a precision vane structure and advanced hydraulic design, ensuring smooth operation and long service life even under harsh working conditions.

2. Key Features

  • High Operating Pressure: Capable of withstanding high working pressure, meeting the demand for high-power hydraulic systems, and ensuring stable output under long-term 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.
  • 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.
  • Wide Compatibility: Suitable for various hydraulic fluids, including petroleum-based oils, water-containing hydraulic fluids, and synthetic hydraulic fluids, adapting to different working environments.

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.
  • 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.
  • When connecting the hydraulic pipeline, ensure that the pipeline is clean and free of impurities, and use appropriate sealing materials to prevent oil leakage.
  • Fill the pump with hydraulic fluid before starting to avoid dry friction between internal components, which may cause damage.
  • 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.
  • 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.

5. Application Scope
