Wilo-Comfort-N-Vario COR-1 MVISE/GE

Water supply plants with a non-self-priming glandless high pressure centrifugal pump and integrated speed control

  • Fully automatic water supply in pressure operation from the public water mains or a storage tank
  • Pumping of drinking water, process water, cooling water, fire-fighting or other process water that does not attack the materials used chemically or mechanically and does not contain any abrasive or long fibre particles
Special features/Product advantages
  • more or less noiseless system through use of glandless stainless steel high pressure centrifugal pumps with integrated frequency converter
  • up to 20 dB[A] quieter than conventional systems with comparable hydraulic power
  • Easy to adjust and reliable through the use of pump series MVISE with integrated dry-running detection and automatic de-activation if the water level is low
