Feed Chamber and Inlet Liners
Feed Chamber & Inlet Liner
Tangential or involute inlet areas face erosion from high-velocity slurry. The inlet profile must match the existing housing.

Hydrocyclone Liners: Match the Material to the Wear Zone
Liners and interface spares for classification, desliming, fines recovery and thickening installations. The hydrocyclone body has no rotating drive parts: liner profiles, inlet and outlet dimensions, sealing and operating pressure are the key requirements. Check Separator discharge regulator parts separately.
Standard Models and Key Dimensions
Size Range and Key Interfaces
Hydrocyclone diameter is only the starting point. Liners must also match the cone angle and the dimensions of the inlet, vortex finder and spigot.
| Size / Series | Published OEM Dimensions | Key Part Identification Details |
|---|---|---|
| Hydrocyclone Product Range | 4–36 in (approximately 100–900 mm as stated by the OEM) | Barrel internal diameter, cone angle, liner thickness and connecting flanges |
| Fines Recovery Configurations | 9 in, 12 in | Feed chamber, vortex finder insertion length and underflow diameter |
| Separator | Installation-specific | Automatic discharge regulator, overflow piping and underflow connection |
4–36 in is the product size range, not an exhaustive model list. Use the nameplate, serial number and interface dimensions for quotation.

Wear Parts
Wear Parts for Feed Chambers, Barrels, Cones and Outlets
Rubber can absorb particle impact in wet abrasive service. Polyurethane selection requires checks of chemical compatibility and temperature; ceramics primarily address abrasive erosion. Select the material for the specific slurry.

Barrel and Cone Liners
Cylinder & Cone Liners
Check the upper barrel and each cone section separately. Preserve internal dimensions, cone angles and joint positions.

Vortex Finders and Wear Inserts
Vortex Finder
Check the internal diameter, insertion length and inlet profile. Bore enlargement through wear changes classification performance.

Spigots and Underflow Inserts
Apex / Spigot
Check the underflow bore, tapered transition and mounting interface. Confirm process requirements before changing the bore size.

Barrel and Cone Housings and Connecting Flanges
Housings & Flanges
For bolted sectional housings, check flange bolt spacing, sealing faces, liner location and design pressure.

Interface Seals and Fasteners
Seals & Fasteners
Match the seal cross-section, compression, slurry medium and bolt specification.

Separator Automatic Discharge Regulator Parts
Automatic Discharge Regulator
For Separator installations equipped with an automatic discharge regulator only; not interchangeable with parts for conventional open-underflow hydrocyclones.

Frequently asked questions
Are liners interchangeable between hydrocyclones of the same diameter?
Diameter alone is insufficient. Also check the inlet profile, barrel and cone lengths, cone angle, liner thickness, flange bolt spacing and vortex finder insertion dimensions.
