Series description
Wilo-Comfort CO-/COR-MVI.../CC

Design

Pressure-boosting system with 2 to 6 non-self-priming high-pressure multistage centrifugal pumps switched in parallel

Application

  • Fully automatic water supply in inlet mode, in the field of public water supply, for pressure boosting from tanks or pressure pipes, for municipal, commercial, industrial and domestic applications (e.g. water supply companies, trade and industrial companies, residential, office or public facilities, administration buildings, hotels, hospitals).
  • Pumping of process water, cooling water, firefighting 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

  • 2-6 pumps of the MVI series per system
  • Automatic pump control via CC switchgear
  • Components that come into contact with fluid are corrosion-resistant
  • Base frame galvanised, with height-adjustable vibration absorbers for insulation against structure-borne noise
  • Shut-off valve at each pump, on the suction and discharge sides
  • Non-return valve, on the discharge side
  • Diaphragm pressure vessel 8 l, PN 16, on the discharge side
  • Pressure sensor, on the discharge side
  • Optional pressure gauge, suction side
  • Pressure gauge, on the discharge side
  • Optional low-water cut-out switchgear
