Paper Making Nozzle
Needle Spray Nozzle
A needle spray nozzle delivers a focused stream of liquid through a small central orifice, which is required when a precise, high-impact jet is needed to clean a narrow slot, a disc filter surface, or a paper web in a paper machine. This CNSS needle spray nozzle is designed for targeted cleaning in tight spaces where a broad spray would be ineffective or wasteful.
No published specification table exists for this listing. Send the duty and the thread on your header and we will confirm the size, pattern and material by email.
Key Benefits
What This Nozzle Gives You
- High-impact jet delivers concentrated cleaning force in narrow or confined areas
- Small central bore allows precise targeting on disc filters or paper web edges
- Threaded fitting with hex nut enables secure mounting and easy adjustment
- Stainless steel construction resists corrosion in wet or chemical environments
- Compact design fits into tight spaces without requiring large clearance
- Free trial samples available to verify fit and function before full order
Application Scenarios
Where It Is Installed
- Cleaning disc filters in a paper machine where debris accumulates in narrow grooves
- Maintaining paper web integrity by removing lint or dust at the edge of a forming section
- Targeted washing of a rotating drum or roller where only a small area needs cleaning
- Precision cleaning in a confined space where spray spread would cause overspray
- Replacing worn nozzles in a paper making line that require a consistent narrow jet
Who It Is For
Buyers Who Specify It
- Paper mill maintenance teams replacing nozzles in forming or press sections
- Machine builders integrating cleaning nozzles into disc filter systems
- Plant engineers troubleshooting clogged or unevenly cleaned filter discs
- OEMs specifying nozzles for paper making machines with tight space constraints
- Facility managers maintaining disc shower systems in industrial filtration
Problems It Solves
What It Fixes on the Line
- Inadequate cleaning in narrow filter slots due to wide or diffuse spray patterns
- Overspray and water waste when a broad nozzle is used in a confined area
- Frequent nozzle failure from misalignment or loose fit in tight mounting spaces
- Difficulty in accessing cleaning points due to bulky or poorly designed nozzles
- Inconsistent cleaning performance caused by variable jet width or pressure drop
Technical Features
How It Is Built

Comparison
How It Compares With the Alternatives
| Full cone nozzle | A full cone provides even coverage over a circular area, suitable for tank filling or gas cooling, but lacks the focused jet needed for narrow slots or disc surfaces |
|---|---|
| Flat fan nozzle | A flat fan spreads liquid across a line, which is useful for broad rinsing, but it cannot deliver the concentrated stream required for a single narrow cleaning point |
| Hollow cone nozzle | A hollow cone creates a ring of droplets ideal for gas scrubbing, but its pattern is unsuitable for precise cleaning in a small bore or narrow gap |
| Spiral nozzle | A spiral nozzle passes solids better due to external vanes, but its spray pattern is not focused enough for high-impact cleaning in a confined bore |
Use Guide
Fitting and Running It
- Confirm the bore size and thread standard against the existing fitting before ordering
- Ensure the standoff distance allows the jet to reach the target without deflection
- Align the nozzle so the central bore is aimed directly at the cleaning point
- Use the hex nut to secure the fitting without over-tightening
- Inspect the orifice for blockage if cleaning performance drops
- Replace the nozzle if the jet becomes misaligned or weak
