THE GRUNDFOS SOLUTION
Therefore, the decision was taken to use a Grundfos CRN 16 pump in combination with a Grundfos CRN
16-160/15SF high-pressure pump, which is able to supply a pressure of 40 bars.

THE OUTCOME
The CRN pumps have proven extremely reliable. They are easy to maintain and service-friendly. The new
system also provides substantial energy-savings compared to the submersible pumps. The savings over the
life of the pumps will be substantial. Their ability to handle large volumes of water means that Grundfos
pumps can be used in a wide variety of situations.

THE SITUATION
This company manufactures and dyes textiles for the
automotive industry and for a number of other
applications.
The company uses cutting-edge dying technology, and
the production process is designed for high quality
and environmental friendliness.

The process makes high demands on the pumps. The
dye contains acids and is used at a temperature of
some 140°C and a pressure of 4.5 bars.

Before a new production run can be started up, a
color test is made in the lab. The dying machines
previously used for the test have been mounted with
stainless steel free pumps with single mechanical
shaft seals which have caused trouble.

An ordinary pump is typically not suitable for liquids at
140°C. And the acid dyes destroy the shaft seal’s
sliding surfaces.
THE GRUNDFOS SOLUTION
Hence the choice of a CRN pumps with a MAGdrive. The pump is made of acid-proof stainless steel and
has a magnetic drive. This drive type handles high temperatures without problems and makes the shaft
seal redundant.

THE OUTCOME
The in-line design of the CRN pump and the high overall reliability meet the customer’s requirement for
few service intervals.

The pump is hermetically sealed. Therefore, the dye is very unlikely to leak and the process is much
safer for the employees – and environmentally responsible. The fact that the pump features a magnetic
drive rather than a traditional shaft seal provides the very hard-wearing and compact solution that was
demanded.

The CRN MAGdrive pumps are unmatched for use in industrial processes that involve aggressive, volatile
or environmentally hazardous liquids.
