The advantages at a glance
� Efficiencies of up to 90%
� Assembly system
� Highly cost-effective thanks
to high efficiency and long
service life
� Cost reduction if self-priming
centrifugal pumps are used
instead of positive displace-
ment pumps
� Decades of experience and
comprehensive process
know-how guarantee
a high standard
Decades of experience in hydraulic ma-
chine manufacturing and comprehen-
sive process know-how form the basis of
our pumps’ top performance. Our high-
quality products and in-depth know-
ledge of starch production processes
generate reliable pumping solutions to
meet the needs of our customers.
ANDRITZ HYDRO offers innovative and tar-
geted pumping solutions throughout the entire
starch production process – from raw material
preparation to extraction and fiber separation,
on to final washing and concentration.
De pending on the branch of industry of the
facility con cerned, we supply centrifugal
pumps with a closed, open, or semi-open
impeller and an integrated vacu um pump.
Foaming liquids, in particular, create one
of the most challenging conditions for
centrifugal pumps. The combination of a
single-stage cen trifugal pump with an in-
tegrated vacuum pump prevents accumu-
lations of air at the impeller inlet and guar-
antees highly efficient pumping operations,
even with fluids at higher viscosities (e.g.
fibrous pulp slurries containing up to 40% air).
The vacuum pump removes the gas con-
tent in the medium in order to ensure that
fluids can be conveyed without any difficul-
ties. As a result of these design features,
self-priming centrifugal pumps from the AD
series are excellently suited for trouble-free
handling of crucial processes.
With the company’s own technical center
ASTRÖ, we have an internationally recog-
nized institute for hydraulic development
and testing at our disposal. Optimization on
a computer using CFD and numerous model
tests are responsible for the high economic
efficiency of the ACP, S, ISO, and AD pump
series.
Professional expertise and our understand-
ing of customer requirements make us a
valuable partner, offering development to
model tests, design, manufacturing, pro-
ject management and installation, to ser-
vice and training – all from a single source.
Customers around the world trust us. They
value our many years of experience through-
out the value chain.
