Millions of Possibilities to Fit Your Needs
The basic Grundfos 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.
Grundfos offers a “Mix and Match” modular approach, so you can configure a pump
that meets your exact needs.
Tested and documented, just like we do for any standard Grundfos pump.
The basic CR pump range is available in four different materials:
cast iron, two grades of stainless steel and titanium.
Thirteen flow sizes are capable of producing up to 180 m3/h at 50 bar,
with a variety of shaft seals, rubber materials and supply voltages.
