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

Water supply plants with a non-self-priming glandless high pressure centrifugal pump

  • 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 glandless high pressure centrifugal pump
  • Up to 20 dB[A] quieter than conventional systems with comparable hydraulic power
  • Reliable through a combination of the pump series MVIS with the control device ER-1
