Disposal
Before beginning installation procedures, these in-
stallation and operating instructions should be stud-
ied carefully. The installation and operation should
also be in accordance with local regulations and ac-
cepted codes of good practice.
1. Handling
The motors of the CR, CRI, CRN 1s, 1, 3, 5, 10, 15
and 20 pumps are supplied with lifting eyes which
must not be used for lifting the entire pump.
When the entire pump is to be lifted, observe the following:
•
CR, CRI, CRN 1s, 1, 3, 5, 10, 15 and 20 pumps fitted with
Grundfos MG motors should be lifted in the pump head by
means of straps or the like.
•
CR, CRN 32, 45, 64 and 90 fitted with Grundfos MG motors up
to and including 11 kW should be lifted by means of the eye
nut fitted to the pump head.
•
CR, CRN 32, 45, 64 and 90 fitted with Siemens motors of
15 kW and up should be lifted by means of the eye bolts fitted
to the motor flange.
•
For other motor makes than those mentioned above, it is rec-
ommended to lift the pump in the pump head by means of
straps.

3. Applications
Grundfos multistage in-line centrifugal pumps, types CR, CRI and
CRN, are designed for a wide range of applications.
Pumped liquids
Thin, non-explosive liquids, not containing solid particles or fi-
bres. The liquid must not attack the pump materials chemically.
When pumping liquids with a density and/or viscosity higher than
that of water, motors with correspondingly higher outputs must be
used, if required.
CR, CRI, CRN
For liquid transfer, circulation and pressure boosting of cold or
hot clean liquids.
CRN
In systems where all parts in contact with the liquid must be made
of high-grade stainless steel, CRN pumps must be used.
