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

The centrifugal immersion pumps of building group 4 are used for wet-pit operation in containers, pits and tanks. Centrifugal immersion pumps for dry-well installation, i.e. to be installed and operated outside the container, are also available.
All components of pumps in plastic design that are in contact with the fluid are made of PP or PVDF. The pump shaft consists of a motor shaft made of stainless steel and a shaft-protecting tube of either PP or PVDF. Built-in elastomers are made of FPM (or also EPDM without surcharge). Centrifugal immersion pumps are equipped with overhang shafts so that there is no need to provide for shaft bearings in components that are in contact with the fluid. Thus, the pumps are safe to run dry and do not require regular service and maintenance.
There is no need of a mechanical sealing of the shaft. Only a so-called gas seal is installed beneath the motor to prevent aggressive vapours from penetrating the motor chamber. But this seal is never in contact with the fluid delivered.
- For aggressive and neutral liquids
- For short-term and continuous operation
