Technical data
Tender text

Compact pressure boosting system according to DIN 1988 and DIN EN 806, for direct or indirect connection. Consisting of non self-priming, switched in parallel, vertically-mounted stainless steel high-pressure multistage centrifugal pumps in glanded versions. 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, 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.
