Product Overview

Create your own
The CR pump can be customised to meet individual require-
ments with unparalleled ease. This is due to the Grundfos
“mix and match” approach to customisation, where the many
pump features and options should be regarded as modules
that can be combined to create the ideal pump for the job at
hand.
In everyday production, Grundfos manufactures a so-called
standard range of CR pumps. This in no way represents the
full potential of the CR technology, but should simply be re-
garded as a reflection of general market demands. In effect,
the standard range is a shortlist of the most popular and
widely applicable multistage solutions around today.
Special designs on request
It is more than likely that we will be able to create exactly the
right pump for you by combining the elements and options
already available within the CR range. But if you have special
requirements or a specific design in mind, let us know. We
will do our best to provide full satisfaction.
Shaft seal options
Sometimes extreme liquids call for extreme measures.
• High temperatures damage seal faces unless precau
-
tions are taken.
• Concern for safety can necessitate special measures
for aggressive, toxic or explosive liquids.
• Liquids can be harmful to shaft seals because they
crystallise, harden or are extremely abrasive.
Pump options
The CR pump elements can handle the most demanding
of liquids and pressures and be adapted to suit many
other requirements.
• Horisontal installation if height is a limitation
• Poor inlet conditions mean that NPSH values must be
adjusted to avoid cavitation.
• Very high pressures demand special solutions.
• You may also need special surface treatments or cer
-
tificates.
Connection options
Your chosen pump elements can be fitted with exactly
the connection options you need. All standards are
covered, and special connection variants are available
for maximum compactness, high liquid pressures, and
so on.
Motor options
CR motors are available in many different configura-
tions to meet the requirements presented by the power
supply, the pumping environment and/or the pumped
liquid itself.
• Power supply systems vary in terms of both frequen
-
cy and voltage, and protection methods also differ
greatly around the world.
• Your environment may be explosive, very hot and/or
very humid. Special conditions also apply at great alti-
tudes.
• The liquid pumped can call for a special motor solu
-
tion. High or low viscosities and/or high or low densi-
ties may require non-standard motor sizes. You may
also need an explosion-proof variant.
