Centrum is a series of 2 to 3 parallel-switched, non-self-priming stainless steel high-pressure multistage centrifugal pumps with speed-controlled motors.

Applications

Centrum pumps provide fully automatic water supply and pressure boosting in inlet mode from a tank, for domestic, commercial, industrial and municipal applications (eg residential, office, administration buildings, hotels, hospitals, trades, industry, water supply companies).

Approved fluids are generally waters which do not attack the materials used, neither chemically nor mechanically, and do not contain any abrasive or long-fiber constituents like:

Drinking water (check drinking water approvals in materials section)
Cooling water
Process water

Key features and benefits

Compact system with outstanding price/performance ratio due to Helix V series stainless steel high-pressure multistage centrifugal pumps
