COR-3 MHIE 403/MS

Compact pressure boosting system according to DIN 1988 and DIN EN 806, for direct or indirect connection. Consisting of non self-priming, horizontal stainless steel high-pressure multistage centrifugal pumps switched in parallel with integrated frequency converters. Ready for connection with stainless steel pipework, mounted on a base frame, including control device with all necessary measurement and adjustment equipment.

For fully automatic water supply and pressure boosting in residential, commercial and public buildings, hotels, hospitals, department stores and for industrial systems.

For pumping drinking water, process water, cooling water or other service water, which does not affect the materials used, neither chemically nor mechanically, and does not contain any abrasive or long-fibre constituents.
