Neptune Hydraulic Metering and Dosing Pumps



Accurate and precise hydraulic metering pumps

The Neptune range of hydraulic metering and dosing pumps can handle high viscosities, high pressures, large and small capacities through their reliable technology.

Typical industries include agriculture, energy, mining, chemical processing, and water/wastewater treatment.

Available Neptune Hydraulic Metering Ranges:

  • Neptune 500 Series – for common applications
  • Neptune 5005/5003 Series – for very low flow applications
  • Neptune 600 Series – high volume/high pressure applications
  • Neptune 6000 Series – low volume/high pressure applications
