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

Special features/product advantages

  • Sturdy system due to stainless steel high-pressure multistage centrifugal pumps of the MVI series
  • Wide hydraulic range through the use of all pumps in the MVI series
  • Easily adjustable and operationally reliable due to the ER-1 control unit used

Series description

Design

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

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.

Consulting guide

Inlet pressure

The maximum inlet pressure (see Technical data) is to be observed for the system configuration. The maximum inlet pressure is calculated from the maximum system operating pressure minus the maximum pump delivery head at Q = 0.

Only for fire protection systems

Version in accordance with DIN 1988 (EN 806), part 5+6

This does not apply to fire-extinguishing systems in accordance with DIN 14462. Please request these separately.

Always observe the specifications in DIN 1988 (EN 806) when using and operating the pressure boosting system.
