Discflo Sludge & Slurry Pumps Discflo has a unique pumping mechanism that is based on the effect of a boundary layer and viscous drag principle, which produces a pulsation-free laminar flow. This technology creates a low-to- no maintenance system by minimizing contact between the pump and the raw material being pumped.
