MATERIALS FOR RAW
PHOSPHORIC ACID
Phosphates are important parts of
agricultural fertilisers. They are obtained
from phosphoric acid as an intermediate
product. In order to obtain phosphoric
acid phosphate containing minerals are
often digested with sulfuric acid. This
process produces extremely corrosive
mixtures containing varied chlorides
and fluorides as well as phosphoric and
sulfuric acids. In addition, a large number
of solids are obtained in form of gypsum
and sand. Due to the chlorides and fluorides very high grade steels have to be
used for metallic materials. A material for
this process must resist high corrosion
loads and exposure to wear.
1.4136S
Excellent wear resistance
As there exists no all-purpose material,
detailed knowledge of the composition
of media as well as material expertise
are important to design pumps with long
operational life in process.

MATERIALS FOR THE

When it comes to pumping catholyte
solutions (NaOH, 80°C) – to protect the
electrolysis membranes from Fe-ions –
only pure, iron-free pump materials
can be considered for use. Rheinhütte
Pumpen successfully makes use here
of centrifugal pumps made from nickel,
ETFE, PFA or PTFE.
On the anolyte side identical pumps
made from titanium, titanium-palladium
or PTFE complement our range. The
pumping of moist chlorine gas presents
supreme demands for the corrosion
resistance of all of the components
which are used.
06
Solid ceramic liquid ring vacuum pumps
have proved their worth for many
decades here and they offer an unique
alternative to special pumps made from
titanium.
Sulphuric acid is used to dry the moist
chlorine gas. At this point, due to the dry
chlorine gas in the sulphuric acid, even
titanium is not suitable as a material for
pumps. Only the special material SIGUSS
which has been developed by Rheinhütte
Pumpen guarantees – along with PTFE
and PFA – long lifetimes for centrifugal
pumps.
APPLICATION
STEEL PICKLING
PLASTIC PUMPS IN
PICKLING PLANTS
Plastics such as PP or PE 1000 have
proven themselves especially in the steel
pickling in recent decades and have
become normal standard. They show no
sensitivity to pH values and chloride
concentrations. Even pure hydrochloric
acid can be handled with these plastics.
In solid-containing pickling PE 1000
(UHMW-PE) is the most appropriate
material.
In very aggressive pickling applications
containing hydrofluoric acid or many
flourids, PVDF proved to be excellent.
Rheinhütte plastic pumps for very
aggressive media can be made of solid
PTFE or plastic lined with PFA.
All plastics can also be used in electrical conductive quality for Rheinhütte
pumps.

RHRS
1.4136S
The 1.4136S is a Rheinhuette special cast
material, which is an enhanced standard
DIN material 1.4136. Rheinhuette Pumpen
has gained best experience with 1.4136S
since more than 25 years. This material is
a corrosion- and erosion-resistant, high
alloyed ferritic cast steel. Typical applications are for example highly oxidising
media, like high-concentrated sulphuric
acid up to 160°C and oleum.
This material is a further development
of the successful material 1.4136S of
Rheinhütte Pumpen. It is ideally suited
for use in highly concentrated and very
hot sulfuric acid up to 240 °C.
Compared to 1.4136S the maximum
temperature in hot concentrated sulfuric
acid was increased again.
The cast material RHRS has a ferritic
basic structure, the composition of which
is characterised by a low carbon content
and alloy content of about 30 % chromium. 2 % molybdenum, and an addition of
copper in the alloy, support the excellent
resistance in concentrated sulfuric acid.
500 µm
Analysis on a Siguss microstructure
Our materials – as
varied as your areas
of applications.
SIGUSS
Siguss is a high-silicon cast iron with
15 % alloying content of Silicon and 5 %
Chromium. The especially high amount
of silicon is the main feature of this cast
material. The high content of Silicon
secures the formation of a ferrosilicitic
micro structure, which is able to form a
very stable and tight passive layer. This
layer protects the metal against corrosion attack. So the material offers very
high resistance against different mineral
acids. No other metallic material offers
this broad application range in sulphuric
acid as Siguss – means from 0 to 99%
H2SO4 up to 250 °C!
Additionally Siguss has a high hardness
of approximately 350 HB. This high
hardness supports the resistance against
erosion-corrosion, which is very typical
for H2SO4. This hardness makes Siguss to
a material which has a better resistance
against abrasion than the most austenitic
stainless steels.
Beside in sulphuric acid, the resistance in
nitric acid is remarkable, too.
Rheinhütte Pumpen manufacture pumps
in Siguss for more then 40 years.
R3020
R3020 is a purely austenitic high-alloy
material. Due to the chemical composition and the specific heat treatment the
structure is practically free of ferretic or
carbidic impurities. The material R3020
is effective in many applications where
the US-material Alloy 20 can be used.
For example, in the field of low and
medium concentrated sulfuric acid, the
corrosion resistance of R3020 and Alloy
20 is quite similar. However, the material
is superior to Alloy 20, because R3020
contains more chromium and molybdenum. This special material of Rheinhütte
Pumpen is one of the so-called highly
corrosion resistant superaustenites.
FRIKORUND®
FRIKORUND® can be used without any
problems in oxidizing and in reducing
fluids with or without chlorides or
bromides. Even if solids need to be
conveyed, the extremely hard material
FRIKORUND® is better suited than any
plastics or many metallic alloys.

11
PROPERTIES
PLASTICS
In pump engineering the non-metallic materials which are mainly used, are predominantly fluoropolymers
and polyolefins. The advantage of these materials is their high resistance to acids and alkalis at low to
medium temperatures. To resist external forces these pump types are usually protected by a metal casing.
POLYOLEFINS
MATERIAL
PROPERTIES AND APPLICATION
Polypropylene PP
In many applications PP represents an economical alternative to high grade metallic
materials. This material is suitable for pumping salt solutions, almost all dilute alkalis and
acids and is also frequently used in hydrochloric acid pickling solutions. It can be used
for working temperatures between 0 °C and 100 °C.
Polyethylene
PE 1000
Ultra high molecular low pressure polyethylene is used exclusively. Its usable temperature range lies between -50 °C and 80 °C. Its general resistance to corrosion sometimes
exceeds that of PP. Due to its very high resistance to wear, centrifugal pumps made of PE
are often used for media which have a corrosive and at the same time an abrasive effect,
as found in waste gas scrubbing plants.
FLUOROPOLYMERS
MATERIAL
PROPERTIES AND APPLICATION
PolyvinylideneFlouride PVDF
PVDF is distinguished by its excellent general corrosion resistance. Its high resistance to
stress cracks and its ability to resist UV. Its temperature range lies between -20 °C and
130° C. This material is particularly suitable for the pumping of hydrofluoric acid at all
concentrations up to boiling point, liquids containing halogens, nitric / hydrofluoric acid
pickling solutions, and for the evaporation of waste hydrochloric acid.
Ethylenetetrafluoroethylene ETFE
ETFE is a fluoropolymer that has proven itself as a lining material and largely covers the
applications like PFA. It can be used virtually universally in a temperature range from
-20 °C to 150 °C in aggressive and corrosive media.
Perfluoralkoxi
PFA
PFA is a perfluorated alkyvinyl ether. Centrifugal pumps lined with PFA can be used up to
180 °C. With a few exceptions this material has a universal resistance to chemicals.
Polytetrafluoroethylene PTFE
PTFE shows an outstandy resistance against nearly all organic and inorganic media over
a wide temperature range. Centrifugal pumps made of PTFE can be used between
-50 °C and 180 °C.
12
PROPERTIES
CERAMICS
Pumps made of ceramic materials are particularly suitable for media which are highly abrasive and at the
same time corrosive, where pumps made from metallic materials and plastics may have a relatively short
operational life.
MATERIAL
FRIKORUND®
PROPERTIES AND APPLICATION
A silicate ceramic material with very high wear resistance due to its high corundum
content. lt can be used up to 120 °C. With the exception of strong, concentrated or hot
alkalis, hydrofluoric acid and liquids containing fluoride, FRIKORUND® can be used in all
aqueous media. This material proved suitable eg. in solid-containing pickling liquor with
elevated temperature.
