Product Details

A low-noise, high-efficiency external gear pumps designed for demanding hydraulic applications. These pumps feature helical gears that minimize noise, vibrations, and pulsations, making them ideal for environments requiring quiet and smooth operation.


  • Displacement: 7 to 35 cm³ per revolution
  • Max Pressure: 260 bar (continuous), 275 bar (intermittent), 290 bar (peak)
  • Speed Range: 500 to 4000 rpm
  • Noise Reduction: Up to 15 dBA quieter than standard gear pumps (~57 dBA at 1500 rpm)
  • Design:
    • Helical Gears – Reduce noise & vibrations
    • High Efficiency – Low internal leakage for better performance
    • Low Pulsation – Minimizes vibrations, extending system lifespan
  • Mounting & Shaft Options: Various flange & shaft configurations (SAE, European standards)
  • Seals: NBR (standard) or FKM (for high temperatures)
  • Fluids: Compatible with mineral & synthetic hydraulic oils
