  • Easy to maintain
  • Simple installation with standard connections

Achieve your required process capacity

If your process flow exceeds the capacity of an individual cyclone, you can operate multiple cyclones in parallel on a common manifold to achieve the capacity you need.

Cyclone manifolds come in a variety of configurations, including radial and inline, with a common goal of providing an even slurry flow, pressure, density and uniform distribution of particle size to each cyclone. We design our manifold systems to not only consistenly distribute the feed, but also collect the overflow and underflow products from the hydrocyclones as required for the application. 

 

For slurries that contain very fine particles combined with low solids concentrations, inline systems are fully adequate, and tend to be less expensive. Their geometry can be more conducive to connection with existing plant piping. For a mixture of fine and coarse particles and higher slurry densities, we recommend a radial system.

 

We customise your manifold to your specific application.

Consistent hydrocyclone performance

Uniform feed distribution
By ensuring the feed to each hydrocyclone in the system is uniform, the manifold allows the system to provide consistent, reliable performance as a unit.
Easy to maintain
Our manifold systems permit convenient removal of any hydrocyclone on the unit without disturbing other hydrocyclones or disassembling the manifold system.
Simple installation with standard connections
Our systems are easy to install, with minimal footprint requirements. All connecting pipe fittings have standard Victaulic grooved or flanged connections. Blank-off connections are provided for any unused hydrocyclone feed outlet pipes.

Custom-designed and built for your application

We offer a number of manifold designs, tailored to fit your specific application. We can usually preassemble these systems, and ship them on a standard flatbed truck.

Radial Manifold


In a radial system, the hydrocyclones are mounted radially around a central vertical feed header for uniform slurry distribution. Slurry outlet nozzles from the feed header incorporate a well-rounded entry configuration to minimise slurry turbulence and wear. The overflow and underflow launders are concentric around the central feed pipe, and provide efficient collection and transfer of products to discharge lines. The launders are designed to minimise splashing.

Radial Manifold "Canister System"


Typically designed for smaller cyclones from 2" to 15". Canister systems cyclones are upright, not tilted.  The underflow rests on an "H" shaped support frame making the footprint small for a manifolded system.

Radial Manifold "Metallurgical System"


Metallurgical systems are used in mining and typically contain between 10 to 24 cyclones. Cyclones sizes range between 20" - 33" cyclones.  Manifolds can be designed with grating and walkways connecting two systems together.

Inline Manifold


Inline Manifolds include a feed distributor, overflow and underflow collection launders, and steel support structure. The hydrocyclones are mounted “in line” with the support structure to reduce space and shipping requirements. An inline feed distributor incorporates a standard nozzle configuration, and is usually branched by the use of standard Ts to minimise cost. Launders are designed in a rectangular shape, reducing lining and steel costs. The underflow launder can be sloped as required for the application, or be designed with a flat bottom.

Spider Manifold


Spider Manifold designs incorporate hydrocyclones that are inclined and mounted radially around the central feed distributor for uniform slurry distribution. Slurry outlet nozzles from the feed distributor feature a standard nozzle configuration. The feed distributor is constructed with a minimum steel plate thickness of 1/4-inch and includes a minimum 1/4-inch vulcanised elastomer lining. For corrosive service applications, the elastomer-lined surfaces are spark tested to ensure complete bonding.

 

With all of our manifold designs, the manifold assembly incorporates the structural steel required to support the radial feed distributor, the hydrocyclones, and the overflow and underflow collection launders. A pressure gauge with protective diaphragm assembly is mounted to the top of the feed distributor. Flanges for sampling and/or a pressure transmitter can be provided. An individual isolating valve can be provided for each hydrocyclone as an optional feature. If elastomer lining is required, it will be a minimum of 1/4 inch thick, and will be vulcanised to the steel.

Pod Manifold


Pod Manifolds are a variation on Radial Manifolds.  When separation required demands the use of very small diameter cyclones, groups of cyclones can be installed in individual “pods” that are arrayed around a central vertical feed header to obtain the required capacity. This design incorporates the same feed header, overflow launder, and underflow launder features of a Radial Manifold, but offers the fine separation only available through the use of small diameter cyclones.  At the same time, it also provides turndown capability not possible if all the cyclones were installed in a single cyclone vessel.

KREBS Cyclone PODS systems are unique and custom designed for your specific needs. They are also known as Cyclone Pod Clusters.
