With the F/FP 425 there is less than 0.05 l residual amount left in a 200 l drum, so maximum 0.02 %. The pump has an integrated backflow valve that is easy to close before taking the pump out of the container. Thus the backflow of the medium in the pump is prevented. This makes optimum use of especially expensive media possible and saves additional cleaning and disposal costs when handling problematic media. The pump is available in stainless steel, polypropylene and hastelloy C. In stainless steel and hastelloy C the pump F/FP 425 can also be used in hazardous areas.

Product attributes

  • With backflow stop
  • Two adjusting levers to easily close the backflow stop
  • With mechanical seal for seal of inner tube
  • Metal core in the inner tube at the PP version
  • Versions for use in hazardous areas available
  • Grease-lubricated shaft bearing
  • Can be combined with various motors as required

Benefits

  • Optimal residual emptying with e.g. less than 0.05 l residual amount left in 200 l drum
  • No tilting to totally empty the drum
  • Reduction of cleaning and waste disposal costs
  • No loss of medium when taking the pump from drum to drum
  • Optimal use of fluids
  • Unique, only at FLUX: the inner tube reinforced by a metal core at the PP version. It prevents leakage and unnecessary wear of the mechanical seal in all operating temperature ranges.
  • Can be temporarily operated against closed valve (hand nozzle, valves etc.) until the indicated temperature of the materials is reached
  • Stainless steel and hastelloy C version can be used in hazardous areas
