Core Function of Apollo Wedge-Wire Nozzles

Advanced Construction & Global Manufacturing Standards

Wedge-Wire Profile (V-Wire) • Non-clogging continuous-slot design
• Best-in-class open area → lower pressure drop
• Precision TIG welding → uniform structural integrity
• Smooth flow path → resistance to fouling & scaling
Metallurgy (Global-Grade Alloys) • SS304 / SS304L
• SS316 / SS316L (Industry Standard)
• SS321
• Duplex 2205, Super Duplex 2507
• 904L
• High-performance alloys: Alloy-20, Monel, Hastelloy C-276 ( on Demand)
Thread Standards • NPT / BSP (¾" to 1")
• Custom OEM designs with nuts, washers, gaskets
Surface Finish • Pickling + Passivation
• Optional Electropolished finish for hygienic applications
Slot Opening & Filtration Accuracy • Full range: 0.02 mm – 6.0 mm
• Standard: 0.20 mm – 0.50 mm
• High-precision tolerance: ±0.05 mm
Global Slot Selection Rule
Slot = 50–70% of media ES (Effective Size)
This ensures:
✔ Zero media leakage
✔ Extended media life
✔ Lower turbidity
✔ Stable headloss

Key Advantages of Apollo Wedge-Wire Nozzles

• Non-clogging wedge wire design
• High hydraulic efficiency
