Flux Drum Pump with Mechanical Seal F 430 / FP 430

Drum pump with mechanical seal F 430 / FP 430

The universal Drum pump with mechanical seal F/FP 430 can be used for various media and is suitable for conveying out of drums, IBCs or tanks. Due to the construction with mechanical seal, the pump can be easily and quickly taken apart into its two main components. This allows good cleanability. Distinct feature, only at FLUX: The inner tube is reinforced with a metal core on plastic models (PP and PVDF). This always allows full function of the mechanical seal. This way, leakage and unnecessary wear are prevented for the complete operating temperature range. Furthermore, it provides highest stability and makes immersion lengths of up to 3 000 mm possible. The versions in stainless steel and hastelloy C are ex-protected. The stainless steel version is also available as FOOD certified version.


  • With mechanical seal for sealing the inner tube
  • Pump can be disassembled into two parts: inner tube cpl. and outer tube
  • Inner tube with metal core on PP and PVDF
  • Versions for use in hazardous areas available
  • FOOD version available
  • Grease-lubricated shaft bearing
  • Can be combined with various motors as required


  • Ideal for frequent medium changes, hardening media, fast drying media, crystallizing media
  • Can be taken apart into main components easily and quickly for cleaning
  • Compared to sealless pump higher service life on abrasive media
  • The inner tube reinforced with metal core on plastic models prevents leakage and unnecessary wear of the mechanical seal in all operating temperature ranges.
  • High stability of the pumps in plastic version enables immersion lengths of up to 3000 mm even here
  • Temporary operation against closed valve (hand nozzle, ball valve etc.) is possible until max. indicated operating temperature
  • Very quiet operation with low vibrations
  • Version in stainless steel and Hastelloy C can be used in hazardous areas
