Rake for Clarifier or thickener

Racleur-épaississeur et clarificateur

LUMPP rakes are designed to work in tanks from 10 to 35 m in diameter, requiring an automatic lifting device. The function of the scraper in the tanks is to concentrate and remove the sludge concentrated in solids up to 30%.

​

Optimizing your clarification or thickener tank

LUMPP engineers optimize the separation of liquids and solids by drawing on 30 years of experience in:

  • the production of phosphate fertilizers,
  • hydrometallurgical plants like nickel.

A connected and reliable scraper

The robust and compact safety device detects overloads in the tank, an automaton triggers the height adjustment of the rakes reducing the resistance. Thus the scraper operates continuously.
Different types of materials depending on your market. Basic stainless steel, 314L, Super Duplex, nickel or titanium alloying, etc …
