The Metso VF Froth Pump has been designed to increase the pump ability of frothy slurry.
The principle of operation is similar to that of hydrocyclone separation. Air is separated from the slurry in a vortex created by the impeller rotation and the tangential inlet to the pump’s conical sump. This results in more efficient pumping at higher capacities and a smooth operation, free from pulsations caused by air locking.
