Isar MODH1-E-1-CH3-LE-404

Compact pressure-boosting system as per DIN 1988 and DIN EN 806 for direct or indirect connection. Consisting of a non-self-priming, horizontal, stainless steel high-pressure multistage centrifugal pump. Ready for connection with stainless-steel pipework, mounted on a base frame, including integrated control by the frequency converter with all necessary measuring and control devices.

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.
