Key Indicators Your Nozzle Needs Replacement

Lechler spray nozzles are engineered for precision but time and harsh conditions take a toll. Here’s how to know when it’s time for a replacement.

Recognize the Damage

Over time, even high-quality nozzles can deteriorate. Common forms of damage that call for replacement

► Wear & Erosion

Abrasion enlarges the internal passages and alters the spray characteristics.

► Corrosion & Rust

Chemical reactions with sprayed media or the environment degrade surface material.

► Chipped or Broken Orifice

Physical damage changes spray distribution and consistency.

► Irregular Spray Patterns

Stripes, heavy center flow, or reduced coverage can all indicate internal wear.

► Caking / Bearding

Buildup from evaporative deposits blocks the nozzle and alters flow.

► Clogging

Entrapped debris restricts fluid passage and leads to uneven spray.


 

Performance Indicators

If you’re seeing these results, it’s more than just maintenance:

These aren’t just nuisances, they’re signs that your nozzle isn’t performing as designed anymore.


 

Choose the Right Replacement

Replacing a worn nozzle restores performance, reduces waste, and protects product quality.
