Design Features of the HydroPulse Spray Nozzle:

  • Provides a controlled intermittent liquid spray using only liquid pressure as the force for atomization. Offers DRIP FREE performance.
  • Interchangeable flat fan, full cone, or hollow cone spray tips
  • Pneumatically actuated for crisp on/off spray
  • Straight through porting for fluid recirculation
  • Hygienic mounting brackets available

Spray Characteristics of the HydroPulse Spray Nozzle:

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

The new HydroPulse (PHP) is a direct pressure spray nozzle with an air actuated shut-off designed to replace current installations where a pneumatic intermittent spray is desired. It is a more compact, lower cost, and easier to maintain solution than competitor models.
