Vertical centrifugal pump 

Part Number: 
1 500 m³/h | VF series
The Metso Minerals VF froth pump has been designed to increase the pumpability of frothy suspensions. The principle of operation is similar to that of hydro- cyclone 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 airlocking.

Summary of design features 
Integrated unit for layout flexibility 
Smooth operation of the open vortex created in the sump and vertical "wet end" inlet prevents air locking 
Cantilever design does not require submerged bearings or shaft seals 
Bearing assembly with double protection sealing 
arrangement to prevent ingress of slurry 
Wear parts are available in a variety of different materials 
Simplified maintenance
