02

Anyone looking for efficient, lasting and economical solutions to their demanding industrial conveyance applications needs more than just a coherent technical concept. Our extensive knowledge of materials, experience of the application, and dialogue with you, the customer ultimately lead to the optimal solution. A way which Rheinhütte Pumpen has been following for over 150 years.

THE RIGHT SOLUTION.FOR ANY FLUID.

SPECIAL MATERIALS FOR SPECIAL REQUIREMENTS

As experts in corrosion and wear re-

sistant materials we offer process and

media-specific solutions. We will select

the right material for your conveyance

requirement and will ensure minimum

wear during long operational life –

even when handling difficult media.

Our extensive pump programme is based

on three groups of material: metals,

plastics and ceramics. Materials which we

at Rheinhütte have developed ourselves

also extend our materials portfolio.

PLASTICS

Plastics provide a good supplement to

many areas of application. Our pumps

are available in six different materials,

each tailored to your specific application.

All manufactured in-house. Plastics

from Rheinhütte Pumpen – more than

just plastic.

CERAMICS

Ceramic materials achieve universal

corrosion and abrasion resistance during

long operational lives. For such applica-

tions Rheinhütte Pumpen offers you with

Frikorund®, a FRIATEC ceramic

development optimised and proven for

pump construction.

The specialist for ceramic materials

and construction.

METALS

Our range includes over 20 different me-

tals. They differ from each other in terms

of their alloying elements, their structure

and their manufacturing process. As eve-

ry alloy has its own characteristic proper-

ties, a suitable material can be used for

each conveyance task:

Rheinhütte Pumpen made from high-

quality stainless steels and numerous

pure metals.

Sulphuric acid can be conveyed with

pumps made of metal or plastic. About

all concentrations and temperatures

Siguss is the only metallic pump material

that can be used.

For highly concentrated sulfuric acid

stainless steel alloys are especially suit-

able because of their oxidative property,

as they form a passive layer for corrosion

protection.

MATERIALS FOR RAW PHOSPHORIC ACID

05

APPLICATION PHOSPHORIC ACID

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 flu-

orides 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.

As there exists no all-purpose material,

detailed knowledge of the composition

are important to design pumps with long

operational life in process.

MATERIALS FOR THE CHLORINE INDUSTRY

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.

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.

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 electri-

cal conductive quality for Rheinhütte

pumps.

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 appli-

cations are for example highly oxidising

media, like high-concentrated sulphuric

acid up to 160°C and oleum.

RHEINHÜTTE PUMPEN MATERIALS – A CLASS OF ITS OWNThrough decades of continuous development of pump materials Rheinhütte Pumpen provides procedural and medium-specific solutions that meet the essential requirements on the resistance of pump materials in use. The realisation of processes often was made possible by specially developed materials from Rheinhütte Pumpen.

RHRS

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 % chromi-

um. 2 % molybdenum, and an addition of

copper in the alloy, support the excellent

resistance in concentrated sulfuric acid.

MATERIAL ANALYSIS AND RECOMMENDATION

Our experts select the optimum materi-

al for your application - considering all

operating parameters and alternative

materials. Static tests in our own labora-

tory and continuous analysis of materials

in use are essential for the development

of alternatives that ensure safe pump

operation.

Expertise also plays a crucial role in

determining the best seal design and

the right pump selection. The close

cooperation and regular exchanges with

renowned institutes, universities and

experts offices guarantee our expertise

up to date.

R3020

R3020 is a purely austenitic high-alloy

material. Due to the chemical composi-

tion 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 molybde-

num. This special material of Rheinhütte

Pumpen is one of the so-called highly

corrosion resistant superaustenites.

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 corro-

sion 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%

H2SO

4 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 H2SO

4. 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.

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.

Our materials – as varied as your areas

of applications.

PROPERTIESPLASTICS

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.

PolyethylenePE 1000

Ultra high molecular low pressure polyethylene is used exclusively. Its usable tempera-ture 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.

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.

FLUOROPOLYMERS

MATERIAL PROPERTIES AND APPLICATION

Polyvinylidene-Flouride 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.

Ethylenetetrafluoro-ethylene 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.

Polytetrafluoro-ethylene 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.

PROPERTIESCERAMICS

MATERIAL PROPERTIES AND APPLICATION

FRIKORUND®

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.

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.
