Type HPH

Multistage centrifugal pump in ring-section design.

 

  • Pump inlet: axial or radial with flanges positioned at 90° increments
  • Discharge flange: radial positioned at 90° increments
  • Replacable rings in composite material to maintain best efficiency and reliability
  • Shaft sealing by stuffing box or mechanical seal
  • Axial thrust compensation by balancing discs, balancing drum or combination of both
  • Easy replacement of all wearing parts
  • Tailormade solutions available:
    • Pump dimensions can be adapted to customer requirements
  • Impellers are fixed by fitting key (e.g. backflushing) possible
  • Impeller wear rings available
  • Pump with one or two connective shaft ends
  • Impellers and diffusers are cast by using ceramic moulds to get smooth surfaces for outstanding hydraulic performance
