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.
Flow rates to 1 500 m3/h - 6 000 USGPM
Heads up to 20 m - 70 ft
The VF pump is suitable for:
- The VF Froth Pump is ideal for all applications involving handling of air entrained slurries, such as fl otation froth in base metal concentrators, phosphate and apatite washing plants and calcium carbonate upgrading plants
- The pump can also be used as a mixing and distribution unit, where dry powder has to be mixed (and wetted) with water
- It can also be used with cement in ready mixed concrete and for grouting
Main benefits for the VF pumps are:
- 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

Main features for the VF pumps are:
- The pump, pump sump and driver are integrated in one selfcontained unit. Simple to install and connect. No alignment or special foundations needed
- The design ensures minimum maintenance and eliminates any requirement for water flushing
- Impeller clearance is maintained by external axial adjustment of the shaft/bearing assembly
