SF/DF Series Peristaltic Pumps — Ragazzini
The Ragazzini SF100, SF190, DF100 and DF190 peristaltic pumps are designed for medium and high flows of thick sludge and dense products. They can transport material over long distances or draw it from significant depths, while offering wide passages for fragile or shear-sensitive products.
