Product Overview

An enhanced impeller design ensures a more stream-
lined flow in the impeller, reducing eddy flow and
friction losses. Tiny margins determine the success
of the final result, so Grundfos aimed for the very
best. We developed a highly specialised laser-welding
technology which facilitates unmatched accuracy.
This technology literally makes dreams come true,
allowing for a seamless transition from the sketchpad
to real life. We use it to bring you impellers of truly su-
perior design and construction, aiming for the point
of theoretical perfection.
State-of-the-art production technology guarantees
the best possible results and gives the CR pumps the
final edge. At Grundfos, we develop our own tools
and processes to ensure a perfect match between
what we want to do and the tools we use to do it.
We never settle for less than ideal solutions when it
comes to making your pumps. The final outcome is
products with near-perfect geometries and toleranc-
es, reflecting the care that has gone into the research
and development stages.

Does a smaller motor sound good to you?
The 10% increase in pump efficiency caused by these im-
provements very often means that a smaller motor can be
used to power the pump at a given duty point. Of course,
smaller motors equal savings on both initial investment costs
and running costs.
Innovation with practical applications
When innovative skill is aimed at creating practical results,
everybody benefits from it. By continuing to apply new and
proven knowledge, the Grundfos CR team raises the bar for
multistage pump efficiency and performance. This means
that you can rest assured that with a CR pump, you get the
best there is.
