Replaceable Polyurethane Flanged Apex Nozzles & Bottom Discharge Orifice Tips
The bottom apex nozzle (orifice tip) is the most critical wear point on any hydrocyclone. Handling concentrated, high-velocity solids separated from the mud stream, the apex orifice suffers rapid erosive wear. As the orifice diameter widens from sand abrasion, the hydrocyclone loses internal air-core stability, causing valuable mud to dump onto the shaker screen beneath.
Our heavy-duty replaceable Polyurethane Flanged Apex Nozzles & Bottom Insert Tips provide drilling contractors, Solids Control refurbishment centers, and slurry plant operators with a durable, easily replaceable solution that restores optimal spray discharge geometry.

Manufacturing Standards & Quality Control
- High-Durometer Casting (Shore 95A): Formulated from specialized abrasion-resistant polyurethane elastomers that maintain orifice edge sharpness under continuous slurry erosion.
- Optional Ceramic Composite Inserts: Available with high-purity alumina (Al₂O₃) inner sleeve inserts for extreme high-sand, abrasive drilling formations.
- Precision Bolt-Hole Tooling: Mounting flanges are cast in hardened steel tooling to guarantee center-to-center bolt hole alignment.
Maintenance & Refurbishment Installation Guidelines
- Orifice Diameter Gauge Checks: Mechanics should use a go/no-go caliper to check the apex inside diameter every 200–300 operating hours. Replace the nozzle when the internal diameter expands significantly over nominal.
- Discharge Pattern Monitoring: Ensure the discharge forms a hollow umbrella/cone spray. If the stream collapses into a solid cylindrical column (rope discharge), swap to a larger diameter apex nozzle or service the cone.
- Flange Gasket Sealing: Ensure the mounting surface on the lower hydrocyclone body is clean of dried mud cake prior to torquing the flange bolts.
Frequently Asked Questions (FAQ)
Q: How do I select the proper internal diameter (ID) for my apex nozzle?
A: Orifice selection depends on solids content and mud weight. Lower solids concentrations run smaller nozzles to minimize liquid loss, while high-sand top-hole sections require larger openings to prevent plugging.
Q: Are these flanged nozzles compatible with standard 10" desander cones?
A: Yes. The 4-bolt and 6-bolt flange bolt circles match standard 10" desander cone lower termination flanges.
Q: Are ceramic-lined apex nozzles available for severe drilling environments?
A: Yes. We supply solid polyurethane nozzles as well as dual-layer composite nozzles featuring an alumina ceramic insert for extended wear life.
