WILO Economy CO-1 MVIS.../ER

Water-supply unit with a glandless, 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 potable water, secondary hot water, cooling water, fire water 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 switchgear.
