3. Performance Characteristics

  • Low Noise Operation: Specifically developed for low noise performance, with optimized vane and stator design to reduce pressure and flow pulsation, ensuring stable and quiet operation.
  • High Reliability: Integral driving parts are assembled as a cartridge kit, allowing easy replacement and maintenance. Key components are made of high-quality materials with advanced heat treatment, extending service life.
  • High Efficiency: The side plate adopts a hydraulic balance design, which can automatically adjust the gap according to working conditions, ensuring high volumetric efficiency and stable performance.
  • Wide Application: Suitable for various industrial scenarios such as injection molding machines, rubber machinery, die-casting machines, metal cutting machines and engineering machinery.

4. Additional Instructions

  • Shaft Rotation Direction: Clockwise (viewed from the shaft end); counterclockwise rotation is available on request.
  • Fluid Compatibility: Compatible with petroleum-based hydraulic oil, anti-wear hydraulic oil, water-glycol and ester-based synthetic fluids; special fluorine rubber seals are required for phosphate ester fluids (marked with “F-” at the beginning of the model).
  • Pipe Flange: Flange kits are not included with the pump; please select the appropriate flange model according to the port size and design standard (JIS, European or North American standard) when ordering.
