Benefits

  • High operating reliability by axial thrust balancing via balance disc and adaptation of pump casing to rotor deflection line
  • Extraction of a partial flow or several partial flows of feed water for use elsewhere in the power station
  • Maintenance-friendly design with easy-to-replace wear parts (bearings, sealing elements, balancing devices) and metal-to-metal sealing of casing
