Enhance your hydrocyclone performance with the proper manifold system

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.

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.

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.
