Design features

CFD pumps easily manage large size particles in dense abrasive slurries and are specifically designed for the most severe slurry applications such as ball and SAG mill cyclone feed plus water-flush crushing in mineral processing plants. They are also suitable for use as slurry transfer pumps on arduous applications such as gravel dredging or coarse coal cyclone feed.

CFD pump hydraulics are based on more than *5 years of fundamental and applied research and backed up by wear performance field trials. Unique design and wear evaluation software ensures high efficiency and optimum life.

CFD designs incorporate the latest in hard alloy and elastomer technology, extending wear life in highly abrasive and corrosive slurries.

Only one pump manufacturer allows operators the flexibility of all-metal or all-rubber lined or a combination of both

The CFD is the only pump for mill circuit applications that has interchangeable materials from a wide range of hard alloy and compression moulded elastomers. This enables optimum materials selection for each specific application ensuring the wear characteristics for each component are balanced.

CFD mill circuit duty slurry pump has a number of unique features

Reduced recirculation is achieved by the deep expelling vanes on the front of the hard alloy impellers. Expelling vane tip turbulence is minimised by the patented extended shroud feature that traps tip vortices and prevents localised scouring on the throatbush face.

Internal liners can be fully worn before replacement as the split outer casing provides structural integrity and high operating pressure capability and safety.
