Wilo-Economy CO-1 MVIS.../ER

Water-supply unit with a glandless, non-self-priming high-pressure multistage centrifugal pump

  • Fully automatic water supply in intake mode, either from the public water supply network or from a tank.
  • Pumping of potable water, process water, cooling water, water for fire-fighting or other water mixtures that do not chemically or mechanically attack the materials used and do not contain abrasive or long-fibre constituents
Special features/Product advantages
  • Virtually noiseless system due to a glandless stainless steel high-pressure multistage centrifugal pump
  • Up to 20 dB[A] quieter than conventional systems with comparable hydraulic output
  • Operationally reliable due to combination of MVIS pump series with ER-1 control device
