Overview

When using the FP 425 drum pump (with mechanical seal to cover inner tube, immersion length 1200 mm), less than 0.05 l of residue is left in a 200-l drum, i.e. a maximum of 0.02 %. The drum pump has a built-in backflow valve which can be closed with ease using two adjusting levers before removing the drum pump from the container. This prevents the medium in the drum pump from flowing back into an emptied drum. This enables optimum use to be made of particularly expensive media and, when working with problematic media, spares the operator additional costs for cleaning drums and disposal. The drum pump is made from stainless steel; it can therefore also be used in areas subject to explosion hazards. If necessary, the drum pump can be combined with different motors.

Benefits

  • Optimum residual emptying leaving e.g. less than 0.05 l of residue in a 200-litre drum
  • No 'tipping' to fully empty the drum
  • Reduction in drum cleaning and/or disposal costs
  • optimum use of costly fluids
  • Medium is not lost when transferring the pump from one drum to the next
  • Can be operated temporarily against a closed valve (pump nozzle, ball cock, etc.), up to stated max. operating temperature
  • Stainless steel version can be used in areas subject to explosion hazards
