Main feed water in nuclear power stations
Main design features
  • Cast casing construction
  • HPTd impeller has low specific speeds to ensure a stable head curve and a wide operating range
  • Impeller with staggered vanes for low pressure pulsation
  • Both diffuser and double volute designs are available to minimize radial thrust and pressure pulsations
  • Multi-lobed high damping radial bearings for rotor dynamic stability. Double acting high-capacity tilting pad axial thrust bearing.
