Start with standard gMAX models and key dimensions to identify inlet heads, cylinder and compound cone liners, vortex finders, spigots, housings and cyclone clusters, then confirm materials and drawing for an enquiry.
gMAX classifies material through the combined geometry of the inlet head, cylinder, compound cone sections and underflow outlet. Before quotation, match the full model, diameter, cone arrangement, vortex finder, spigot, liner material, serial number and drawings to the same unit.
Diameters and capacities come from the official FLS KREBS brochure. Published capacities at 10–30 psi support model identification only. Actual selection and spares require the individual installation records.
| Series / model | Standard diameter / structure | Published capacity | Application and document status | Required spare identification |
|---|---|---|---|---|
| gMAX Hydrocyclones | Metal housing / replaceable liner series | Project-specific combination of diameter, inlet, cylinder, cone angle, vortex finder and spigot | Mineral processing, oil sands, power generation, chemicals, industrial manufacturing and water treatment | Confirm parts against the full model, serial number, structural configuration and drawing revision |

Follow the slurry through entry, pre-classification, cylindrical swirling flow, cone classification, overflow and underflow. Each item links to the relevant part and material pages.
Inlet Head / Feed Chamber Liner
These liners face high-velocity slurry erosion and particle impact in the tangential inlet and pre-classification zone. Check the full gMAX model, inlet direction and size, internal profile, liner segments, thickness, hole pattern, seals and adjacent cylinder interfaces.
View Part Details →
Inlet Nozzle Liner
These protect the feed interface and areas with the greatest flow-direction changes. Check inlet cross-section, flange, flow direction, profile, liner projection, end seals, fastening method and inlet head fit.
View Part Details →
Cylinder Liner / Upper Liner
These protect the cylinder below the inlet head and maintain its critical inside diameter. Check cylinder diameter, section count, liner inside/outside diameters, length, flanges, hole patterns, joints, locating shoulders, swirl direction and inlet head position.
View Part Details →
Upper and Lower Cone Liners
The gMAX compound cone liners determine the classification flow field and face increasingly concentrated abrasion. Check each cone's angle, length, large/small end diameters, flange, sequence, liner thickness, joints and transition to the underflow outlet.

Vortex Finder
The vortex finder fits at the top centre and controls the overflow passage. Check insertion depth, inside/outside diameters, overall length, top flange, fastening method, top cover liner fit and permitted wear.
View Part Details →
Vortex Finder Insert
These are replaceable wear components in the overflow passage. Check inside diameter, wall thickness, insertion length, steps, locating shoulders, top retention, fit with the vortex finder body and passage roundness.
View Part Details →
Apex / Spigot
The spigot sits at the lowest point and determines the underflow outlet. Check full model, bore, shape, taper, overall length, flange or clamping method, insert structure, permitted wear and final cone interface.
View Part Details →
Apex Insert
These restore or adjust critical spigot flow dimensions. Check bore, outside diameter, length, taper, steps, fastening method, mating housing and target underflow conditions.
View Part Details →Hydrocyclones have no mechanical drive parts. This section covers structural spares directly related to pressure boundaries, liner support, manifolds, valves, seals and site installation.
Inlet Head Body
These support the inlet, top cover, vortex finder and cylinder interfaces. Check housing material, inlet direction, flange standard, hole pattern, pressure rating, top cover, liner cavity dimensions and lifting positions.
View Part Details →
Cylinder Section and Ring
These form the pressure boundary and liner support between the inlet head and cones. Check diameter, section length, flanges, hole spacing, seal grooves, housing thickness, connecting rings, liner cavity and adjacent section orientation.
View Part Details →
Cone Section Body Assembly
Multi-section cone housings must retain the correct sequence, cone angles and flow continuity. Check each section's large/small end diameters, length, flanges, hole patterns, housing material, liner space, seals and supports.
View Part Details →Cluster Manifold, Valves and Support
Multiple cyclones form a cluster through feed manifolds, isolation valves, overflow/underflow collection, supports and instruments. Check unit count, pipe diameters, valves, pressure ratings, interfaces, centre distances, supports and site layout.
View Part Details →The FLS gMAX brochure lists BPC rubber, neoprene, nitrile rubber, chlorobutyl rubber, alumina, nitride-bonded silicon carbide, reaction-bonded silicon carbide and sintered α silicon carbide liners. Unlined housings include 304L/316L, Duplex 2205, CD4MCU, Monel, Inconel, Nickel, Hastelloy, other metal alloys and polyurethane. A material name alone is not a manufacturing specification: installation position, pressure, abrasion, corrosion and original structure must also be confirmed.
No. Also check the full model, inlet head, cylinder, cone arrangement, vortex finder, spigot bore, housing and liner materials, serial number and drawing revision.
Screen rubber, polyurethane, alumina, silicon carbide ceramics and corrosion-resistant alloys by installation position and failure mode, then confirm against original structure, operating conditions, dimensions, drawings and acceptance requirements.
Provide the full model, serial number, inlet direction, cyclone diameter, cone arrangement, vortex finder, spigot bore, drawings or samples, used-part photos, material and operating conditions. We use these to identify parts, assess materials, match manufacturing requirements, control quality and deliver finished components.
