Wilo-Comfort-Vario COR-1 MHIE/GE

Water supply plants with a non-self-priming 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
  • robust system through stainless steel high pressure centrifugal pumps, series MHIE, with air-cooled integrated frequency converter
  • Extremely wide control bandwidth of the frequency converter
  • Integrated full motor protection via PTC
  • Integrated dry-running detection with automatic de-activation at low water via the performance characteristic of the motor control electronics
