Design Features of the HydroPulse Spray Nozzle:

  • The precise intermittent spray uses liquid pressure as the force for atomization
  • Improves product quality with uniform, repeatable coverage and drip-free performance 
  • Interchangeable flat fan, full cone, or hollow cone nozzle tips provide a wide range of spray patterns and volumes to match requirements
  • Pneumatically actuated for crisp on/off precision spray directly on the target
  • Minimal overspray reduces waste and maintains a clean, safe environment
  • Straight through porting for fluid recirculation
  • Hygienic connections and mounting brackets are available options

Spray Characteristics of the HydroPulse Spray Nozzle:

  • Relatively coarse atomization
  • Uniform distribution with tapered edges for use in overlapping sprays

Improved Spray Performance

BETE’s Pneumatic HydroPulse (PHP) offers the latest innovations in pneumatically actuated spray technology. Such intermittent spraying solutions are ideal for precision coating, lubricating, and moistening applications in Food Processing and other industries – saving valuable spray media while enhancing product quality.
