Worldwide B2B pump supply and export

This selection covers CRE only: standard AISI 304 hydraulics, HQQE seal and three-phase supply for 50 Hz systems. CRIE, CRNE, single-phase, HQQV and prices are excluded.

The official catalogue supply is 3 × 380–500 V, 3 × 380–480 V or 3 × 400–480 V depending on motor power. The exact range is shown for every article code and covers the applicable part of European 380–415 V networks.

Numeric head values are read at Q=0 from the official 2026 Grundfos vector curves at maximum curve speed and rounded to the nearest metre. They support comparison and preselection.

Use Grundfos Product Center or the product datasheet for contractual duty-point sizing. No prices are published on this page.
