PBU Series‚Äč

Horizontal centrifugal pumps for the transport of liquid-gas mixtures and for the enrichment of liquids with gases. A dispersion with very fine bubbles is being achieved. Therefore the multiphase pumps are also acting as dynamic mixer with high shearing forces. Some main applications are water and wastewater treatment, dissolved air flotation, neutralization, biofuel plants, bio-reactors, ozonation, crude oil water separation on oil fields and oil rigs as well as general process technology.


  • Optimal enrichment and mixing of liquids with gases
  • High degree of dispersion
  • Low velocity of flow
  • Optimized impeller approach flow
  • Low internal friction losses
