  • Improved efficiency and NPSHreq by experimentally verified hydraulic design of impellers (vanes)
  • Operating costs reduced by trimming the nominal impeller diameter to match the specified duty point
  • Little wear, low vibration levels and excellent smooth running characteristics thanks to good suction performance and virtually cavitation-free operation across a wide operating range
