Urethane Hydrocyclones

FLSmidth Krebs Urethane hydrocyclones are ideally suited for classification and separation of solids in slurries in the industrial and mineral related wet processes. Their light weight construction, small footprint and ease of handling makes this the best option in many water & industrial and mining applications.

FLSmidth Krebs has a complete line of urethane hydrocyclones ranging in size from .5 to 15 inch (13 to 254 mm) in diameter.

The gMAX cyclone performance level was formerly only achievable using many small diameter hydrocyclones, at a much higher capital cost.

Our gMAX technology is available in most urethane sizes. The gMAX cyclone design includes modern apex and cone designs that feature performance enhancing benefits. The cyclone inlet and cylindrical sections have been modified to minimize turbulence and wear, but still have the capability to operate at much higher capacities than other hydrocyclones of the same diameter.

Separation d50's as fine as 3 microns are possible with flow rates ranging from .6 to 300 gpm (14 to 68 m3/hr) and higher per hydrocyclone. Multiple units can be combined in a manifold arrangement for unlimited capacities.

    • Low cost

    krebs cyclones pod system

    Pod System: Where 1” or 2” diameter cyclones are required for the
    desired separation and the process flows are very large; our pod style manifolds
    combine several standard size cyclone “pods” onto a radial manifold system.
    This provides very high capacity while offering some turndown capability,
    spare capacity, and fewer valves to maintain.
