Design
Comfort-N-Vario COR MVISE-VR isPressure boosting system with 2 to 4 parallel-switched, non-self-priming stainless steel high-pressure multistage centrifugal pumps with speed-controlled glandless pump motors
Application
- Fully automatic water supply and pressure boosting in residential, commercial and public buildings, hotels, hospitals, department stores and for industrial systems.
- Pumping of potable water and 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 benefits
- System is virtually noise-free in operation due to 2-4 parallel-switched, glandless stainless steel high-pressure multistage centrifugal pumps with integrated, water-cooled frequency converter
- Up to 20 dB[A] quieter than conventional systems with comparable hydraulic output
- Control range of frequency converters from 20 to 50 Hz
- Operationally reliable through the use of the MVISE pump series with integrated dry-running detection and automatic deactivation in the event of low water
- Customised units on request
