Rheinhütte Centrifugal Pumps

The basis of the comprehensive pump range of the  German pump manufacturer Rheinhütte Pumpen consists of three material groups Metal, Plastics and Ceramics. Rheinhütte Pumpen develops individual concepts for sophisticated applications  providing flexible and economic  solutions for special projects. Rheinhütte Pumpen also offers an extensive pump range for standardized applications.

 

Areas of Application:

Cathodic Dip Coating Process

Chlor-alkali Electrolysis

Concentrated Solar Power

Fertiliser Production

Flue Gas Cleaning in Waste Incineration Plants

Industrial Manufacture of Sulphuric Acid

Molten Salts

Molten Sulphur

Production of Titanium Dioxide

Steel and Stainless Steel Pickles

 

Materials:

Metal:

More than 30 types, cast iron,  cast steel,  silicon iron,  high alloyed metals,  nickel based metals,  pure metals.

Plastic:

All common plastics available, PP, PE1000 (UHMWPE), PVDF, ETFE, PFA, PTFE.

Ceramics:

Will work if nothing else does, Frikorund®,  Frikotherm®,  SiSiC.

 

Plastic Materials: Polyolefins

Polypropylen PP

economical alternative to high grade metallic materials

suitable for pumping salt solutions, dilute alkalis and acids,         hydrochloric acid pickling solutions

working temperatures between 0° C (32 °F) and 100° C (212 °F)

 

Polyethylene PE 1000 (UHMW-PE)

ultra high molecular low pressure PE is used

temperature range between -50° C (-58°F) and 80° C (176 °F)

general resistance to corrosion

high resistance to wear

 

Plastic Materials:  fluoro-polymers I

Polyvinylidenfluorid PVDF

excellent general corrosion resistance

high resistance to stress cracks and ability to withstand UV

temperature range between -20° C (-4° F) and 130° C (266° F)

suitable for pumping hydrofluoric acid at all concentrations up to
   boiling point, liquids containing halogens, nitric/hydrofluoric acid
   pickling solutions, evaporation of waste hydrofluoric acid

Not useable in caustic fluids; pH >12 !!!!

 Ethylenetetrafluoroethylene ETFE

is a fluoropolymer that provides an inexpensive alternative to PFA

temperature range between -20° C (-4°F) and 150° C (302 °F),
    (in special cases up to max. 170 °C (338 °F)) in aggressive and corrosive media

 

Plastic Materials:  fluoro-polymers II

Perfluoralkoxi PFA

PFA is a perfluorated alkyvinyl ether

centrifugal pumps with PFA-lining can be used up to 180° C (374° F)

nearly universal resistance to chemicals

 

 

 Polytetrafluorethylen PTFE

tradename Teflon - but not extrudeable!

shows an exceptional resistance against nearly all organic and inorganic media over a wide temperature range.

Centrifugal pumps made of PTFE can be used between -50 °C (-58 °F) and 180 °C (356 °F)
