Pump Diagnosis – Low Consistency Brownstock Pulp

Purpose of the Equipment

  • Transports low consistency brownstock pulp from a mix chest to a wash press.


  • Significant vibration and a long history of reliability issues
  • Inefficient operation
    • Peak flow rate: 67% of Best Efficiency Point (BEP)
    • Average flow rate: 38% of BEP
  • Periodic cavitation
