The all-rounders for the continuous separation or clarification of liquids

Fast. Flexible. Resistant.

High-speed tubular centrifuges are used mainly for separating solid components from fermenter suspensions. But this type of centrifuge can also be used to separate two liquids and remove a solid at the same time (only specific density differences are suitable). The max. throughput will be reduced at liquid-liquid separation. The liquid is fed into the rotor from below while the centrifuge is running. The suspension components are stratified by density in the rotor. The liquid(s) is or are discharged continuously via the run-off tray. The solid remains in the rotor.


  • Continuous feed, manual solids discharge
  • Throughput ranging from a few litres to 3,000 l/h
  • g-force max. 16,000 – 80,000
  • Solids uptake* 0.25 – 10 litres *depending on the solid

*The maximum throughput refers to optimum product parameter. The suggested refers to a residence time of 1 minute. The throughput will be reduced at all High-speed Centrifuges when using a bottom valve or at liquid-liquid separation up to 50%. All figures are approximate values. Subject to amendment and errors.
