Series description
Wilo-Comfort-Vario COR-1 MVIE...-GE

Design

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

Application

  • Fully automatic water supply in inlet mode, either from the public water supply network or from a tank.
  • Pumping of drinking water, process water, cooling water, fire water (apart from fire-extinguishing systems in accordance with DIN 14462 and with the approval of the local fire safety authorities) or other types of industrial water that do not attack the materials either chemically or mechanically and do not contain abrasive or long-fibre constituents.

Equipment/function

  • 1 MVIE series pump with infinitely variable control mode via integrated frequency converter
  • All components in contact with the fluid are corrosion-resistant
  • Check valve, pressure side
  • Non-return valve, pressure side
  • Diaphragm pressure vessel 8 l, PN16
