The high-pressure pumps of the HP series are designed for pumping liquids in petrochemical plants, boiler feed water, condensate, reverse osmosis, oils, and fuels and are suitable for applications such as:

  • boiler feed water applications 
  • applications in the oil and gas industry
  • booster application in all industrial branches 
  • applications in refineries
  • water injection onshore and offshore

  • Q= 600 m³/h
  • H= 2500 m
  • P= 250 bar
  • T= +250 °C
GP quarter cut
  • injector pump of “back-to-back” arrangement
  • version with NPSH impeller
  • axial thrust compensation by means of “back-to-back” arrangement of impellers
  • bearings: antifriction bearings or slide bearings
  • very stable rotor dynamics also in case of large number of stages
  • central slide bearing ensures very smooth running and low vibration values
  • very small load on axial bearings due to back-to-back arrangement, long service life
  • grey cast iron
  • ductile cast iron, ADI materials
  • cast steel
  • 12 % chromium steel
  • austenitic steel
  • special alloys

  • Standard Version
    Radial bearings: antifriction bearings
    Axial bearings: antifriction bearings
    Ring oil lubrication
     
  • Variant
    Radial bearings: slide bearings
    Axial bearings: antifriction bearings
    Ring oil lubrication
     
  • Variant
    Radial bearings: slide bearings
    Axial bearings: slide bearings

GP - wear-resistant design
GP - wear-resistant design
  • Injector pumps of wear-resistant design for especially abrasive liquids, liquids containing solids
  • Even on wear of clearance spaces the remaining axial thrust is changing just slightly, bearing load of axial bearing remains equally low.
