An additional benefit of this froth impeller design
and oversized inlet is that it raises the solids
concentration limits that a centrifugal pump can
handle. As the main problem of handling froth
is similar to that of handling viscous slurries -
namely, getting the slurry into the pump so it
can be pumped - this pump has proven to be a
high performer in dense media viscous slurries.
Additionally, flow surging problems common to other
centrifugal pump designs at low flows are eliminated
for viscous slurries.
