High-pressure pump

HP

High-pressure horizontal multistage pumps, HP

Horizontal high-pressure pumps coupled to a standard motor by a rigid coupling, used singly or as two in series. Impellers are arranged back to back to balance the axial force. Used where very high head is needed at moderate flow.

  • One pump or two in series
  • Back-to-back impellers balance axial force
  • Highest heads in the catalogue
  • Water treatment, boosting and flushing duties
