Main Applications

• Power stations
• Also Boiler circuits or primary circuits
• Boiler recirculation

LUVA Benefits

• Reliable operation:
  • Completely forged pressure enclosure
  • Hermetically sealed (zero leakage, also no mechanical seals)
  • Bearings designed for the highest loads
  • Also Optimised thermoelastic design
• Reliability during upset conditions:
  • Motor cooling through thermosyphon effect
  • Also Optimised heat barrier minimises heat transfer to the motor; also no heat barrier cooling required
• Pump Low power consumption:
  • Well-proven design with high hydraulic efficiency
  • Also Wet winding technology for high motor efficiency
• Low life cycle costs:
  • Long maintenance intervals
  • Also Long reduced-shank studs to cope with high pressure and also temperature transients
  • Special winding technology for long motor service life
• Low maintenance costs:
  • Pull-out design for straightforward replacement
  • Optimised rotor-dynamic behaviour with low vibrations
  • Also Easy access to wear parts
