WILO Comfort-Vario COR MVIE.../VR

Pressure boosting system with 2 to 4 non-self-priming stainless steel high-pressure multistage centrifugal pumps switched in parallel with speed-controlled motors and Vario controller VR.

Application

■ Fully automatic water supply and pressure boosting in residential, commercial and public buildings, hotels, hospitals, department stores and industrial systems;
■ Pumping of potable water and process water, cooling water, fire water (except for fire extinguishing systems in accordance with DIN14462) or other service waters that do not attack the materials used, neither chemically nor mechanically, and do not contain any abrasive or long-fibre constituents.

Special features/product advantages

■ Heavy-duty system due to MVIE series stainless steel high-pressure multistage centrifugal pumps with air-cooled integrated frequency converters;
■ IEC three-phase motors (Level IE2), from 0.75 kW, 2-pole;
■ Superproportionally large control range;
■ Integrated dry-running detection with automatic deactivation in the event of low water via performance characteristics of the motor control electronics.
