Froth Pump Won’t Airlock
GIW Industries says its new High Volume
Froth (HVF) pump can pump froth without
airlocking—a new hydraulic design actual-
ly removes air from the impeller eye while
the pump is running. The GIW HVF, which
can be retrofitted into many existing froth
applications, features a de-aeration system
that includes a patent-pending vented
impeller and airlock venting. This helps to
eliminate sump overflow due to pump air-
lock, reduces downtime and allows water
use to be restricted to the bare minimum. Fewer pumps are required for less capital
expense, requiring less water and power
usage. According to GIW, the pump has
been fully tested on both froth and viscous
liquids. Designed for air-entrained slurries,
the pump has many possible applications
in mining, including phosphate and oil
sands as well as hard-rock operations.
