Product Overview

Heavy motors can stay in place with
the Grundfos spacer coupling
Minimising downtime is also part of reliable op-
eration. That is why Grundfos has eliminated a major
nuisance for owners of large pumps. Now, it is no
longer necessary to
remove heavy motors
to replace the seal:
The innovative spacer
coupling, unique to the
CR range, means that
all motors weighing
more than 35 kg can be
left in place during seal
replacement.
All Grundfos pumps are thoroughly tested before they
leave the factory.
When nothing else will do: The titanium CR
After dry running, corrosive liquids are the second-most com-
mon cause of pump failure and shortened pump lifetimes.
High-grade stainless steel makes the Grundfos CR very resist-
ant to corrosion, but for extremely demanding applications,
true reliability requires the titanium touch.
The CR is the only pump of its kind to come in a full-titanium
variant. Now a financially viable alternative, titanium offers
a reliability which other materials simply cannot match. Not
even a decade of full immersion in salt water will leave a
blemish on the metal surface.
Reliability in production
At Grundfos, we practice tight control over every aspect of
the production process. Absolutely nothing is left to chance.
Our production is certified in accordance with the strictest
international standards (ISO 9001) and subjected to rigorous
process control.
Remarkably, each CR pump is tested before leaving the
factory. Every single one. They are tested for performance,
power consumption, and static pressure. This careful testing
is the only way to be certain that all pumps meet the stand-
ards you have a right to expect from a Grundfos CR solution.
