process | Handling Fibrous Media
Large amounts of fibrous water – but no clogging
THE SITUATION
A large-scale potato flour factory processes
approximately 180,000 tonnes of potatoes each
season. Besides potato flour, the end products include
potato protein and pulp for feed. Naturally, energy
efficiency is a key consideration at the facility – partly
because reductions in energy consumption make the
company eligible for public-sector subsidies for certain
projects. A hydro cyclone system separates the raw
material – the potato – into media of varying
viscosity, and these substances need to be
transported in an efficient manner with minimal
downtime.

THE GRUNDFOS SOLUTION
Grundfos installed 7 CRN centrifugal pumps, which
fulfill a crucial function by pumping the various
media to be transported.
THE OUTCOME
As will be evident from the feedback quoted above,
the Grundfos pumps have proven that they are
equal to the task of transporting even very fibrous
media with no problems whatsoever. And of course
the energy savings are always welcome. Two more
reasons why prospective clients can be sure that
Grundfos is the right supplier for them.

THE PRODUCTION MANAGER IS ENTHUSIASTIC
IN HIS PRAISE OF THE NEW GRUNDFOS
SOLUTION:
“Our production plant has performed like a dream –
with minimal downtime.
The new Grundfos pumps, seven in all, replace nine
old pumps that were no longer financially viable.
The Grundfos solution cost only a fraction of a
traditional pump solution, but even so, the purchase
price was not the main benefit.
We saw much better performance with the new
pumps.
And of course the fact that energy consumption was
down by 50 percent was also important”.

process | CUSTOMISED SOLUTIONS
Working with the customer for that special solution
THE SITUATION
This company manufactures chemicals. During the manufacturing
process it is crucial to avoid leakage. The pumps are often required to
deal with liquids at high temperatures, and to handle vacuums, etc.
The company had a particular problem:
In connection with a distillation process, a CRN pump with a double
seal circulates the liquid. This process is carried out under a 95%
vacuum, and as the pump is placed approximately 2m below the water
surface, we are in problem territory for pump suppliers. Vacuum
operation typically causes the following problems:
1. The seal opens up, which means that air is drawn into the plant. This
can ruin the seal when the pump is restarted, and air may also have
an adverse effect on the process. This is solved by using a double seal.
2. When it comes to a stop, the pump is drained and cannot be
restarted without being primed. This is solved by applying a vacuum
pipe directly at the top of the pump and by using the re-circulation
function in the pump suction chamber.
All in all, the company needed a product that was 100 per cent adapted
to customer requirements.
THE GRUNDFOS SOLUTION
The company has always been very satisfied with Grundfos’ pumps,
which they use for supplying heat and water to the factory. In 2001,
they collaborated with Grundfos on a process oriented solution to the
problem
above. This would require a different type of pump.
The answer was a stainless steel centrifugal pump (CRN) fitted with O-
rings that are resistant to chemicals. This version has a double
mechanical shaft seal that can withstand liquid temperatures of up to
120°C indefinitely.
There is also a barrier fluid chamber that prevents leakage, meeting
the company’s environmental requirements of a leak-free pump that
would perform perfectly under the specified conditions in the plant.

Multistage centrifugal pumps for cardboard
manufacture
manufacture
THE SITUATION
This company has been manufacturing cardboard for over 90 years. The factory produces 70,000 tons of
grey board and 90,000 tons of duplex cardboard; up to 320 meters of cardboard rolling off the conveyors
every minute!
These days, the main raw material is no longer straw, but recycled paper. The paper is mixed with large
quantities of water and pulped using large cutters. This pulp is then transported via conveyor belts over a
filter or a sieve to remove the surplus water. In order to prevent the filter becoming blocked, it must be
cleaned continuously, which is done using high pressure water jets. Previously, the traditional submersible
pumps were used in order to achieve the required pressure.
However, this system had a number of drawbacks: high energy consumption, high purchase and
maintenance costs and leakages.
