Marzocchi Pumps

ELI3 Series Gear Pumps

The ELI3 Series comprises low-noise, high-efficiency external gear pumps engineered for demanding hydraulic applications. These pumps feature helical gears that significantly reduce noise and vibrations, making them ideal for environments where noise reduction is critical.

  • Displacement: 20.4 to 87.1 cm³ per revolution
  • Max Pressure: 250 bar (continuous), 275 bar (intermittent), 290 bar (peak)
  • Speed Range: 200 to 3500 rpm
  • Noise Reduction: Up to 15 dBA quieter than standard gear pumps
  • Design:
    • Helical Gears – Reduce noise and vibrations
    • High Efficiency – Minimizes internal leakage for better performance
    • Low Pulsation – Reduces system vibrations, extending 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
