Grundfos CR – Multi-Stage Centrifugal Pumps

Grundfos CR — Grundfos CRE — Grundfos CRI — Grundfos CRN

The basic CR pump range, which can be applied in almost any industrial solution, is already in itself the broadest range available.
Through its modular approach, Grundfos has made it even broader.
Modularity for a complete range of pump solutions; from four material variants, thirteen flow sizes (up to almost 50 bar of pressure), a variety of shaft seals, rubber materials, and supply voltages. Pump parts can be optimised and designed for specific requirements. The CRE pump is a CR pump, motor and integrated variable frequency drive. The CRE pump is a system which is able to solve application problems and save energy.
