High Pressure Dosing Pumps

Rubicon Science is pleased to offer Knauer’s wide range of German-designed and manufactured high pressure dosing pumps. They are highly accurate two-piston pumps for applications in the chemical and pharmaceutical industries as well as in research and method development. They pump and dose aqueous and organic liquids, aggressive media or liquid gases. The metering pumps have high chemical resistance, excellent flow rate precision and low pulsation of the pumped medium in a wide range of applications: 

  • Flow rates from 0.01 ml/min to 1,000 ml/min
  • High pressure range up to 1000 bar 
  • Wide temperature range from -10 °C to 120 °C
  • Viscous liquids up to 1,000 mPa-s
