Various materials for every application

The FLUX range offers different variants for nearly every performance requirement.



S = Stainless steel (316 Ti)

  • Used with shafts, pumps, housings and hand nozzles
  • Used with highly flammable media, acids and alkalis, solvents and for pharma/food applications
  • Weldable
  • Electrically conductive
  • Very often used in the chemical industry

HC = Hastelloy C (24610)

  • Highly corrosion-resistant nickel-molybdenum alloy
  • Used with shafts and pumps
  • Used with acids and alkalis and very aggressive media
  • Weldable
  • Electrically conductive
  • Very expensive (factor 3.5 at drum pumps compared to stainless steel)

Al = Aluminium (AlMg5)

  • Used with pumps and hand nozzles
  • Mostly used for oils (diesel, hydraulic oil), but also for neutral, not-flammable media
  • Weldable

Must not be used for highly flammable media as an electrically non-conductive oxide layer may form on the surface of the pump!


GG = Grey Cast Iron

  • Used for housing of air-operated diaphragm pumps
  • High surface hardness
  • Especially used for abrasive media

Ti = Titanium

  • Used with shafts of drum pumps
  • Good resistance against very aggressive media
  • Used with hydrofluoric acid, iron-III-chloride or in case HC is only limitedly resistant


For almost every medium the optimum material
