Centrifuges for pilot plant duty

Applications :

pilot plant or small-scale production centrifuges A wide range of centrifuges for pilot plant or small-scale production
  • For solid-liquid filtration or solid-liquid decantation.
  • Can be used for simple or complex processes.
  • Capable of a wide range of duties (explosive environments, hazardous materials, corrosive materials…)
  • For all types of products, from bulk chemical to high value added products.
  • For single products or multiple products.
Range :
    Top discharge centrifuges (manual or removable filter bag) :
  • Vertical basket centrifuge - Model RC 40 / 50 / 60
  • Vertical decanters - Model SLAB 420 / 540
    Other basket centrifuges :
  • Automatic models : solids discharge via a scraper
  • Simplified models : directly coupled motor
Top discharge centrifuges (manual or removable filter bag) :
Centrifugal filtration
Centrifugal Solid-Liquid separation using a perforated basket equipped with a filter cloth or removable filter bag.
Centrifugal filtration
Centrifugal decantation
Centrifugal Solid-Liquid, Liquid-Liquid, or Solid-Liquid-Liquid separation in a solid bowl. Liquid removal using a skimmer or by overflowing the bowl rim.
Centrifugal decantation

Vertical basket centrifuges - Model RC 40 / 50 / 60

A wide variety of technical characteristics, optional equipment, and features to adapt the centrifuges to your specific needs.
