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


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


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)
