HydroPulse® Nozzles

Direct pressure spray nozzles with air actuated shut-off

We Can Help!

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 spray tips
  • Pneumatically actuated for crisp on/off spray
  • Straight through porting for fluid recirculation
  • Variety of 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 (HP) is a direct pressure spray nozzle with an air actuated shut-off designed to replace current flat fan installations where an intermittent spray is desired. It is a more compact, lower cost, and easier to maintain solution than competitor models.

Key Features of the HydroPulse Spray Nozzle:

  • Simple and maintenance-friendly design allows for disassembly, inspection/cleaning, and reassembly with basic hand tools
  • Internals can be removed in one simple operation!
  • Can be rebuilt without uninstalling entire spray assembly
  • Air Cylinders are not integrated and are easily replaceable
  • Fluid Connection Size: 1/8, 1/4, Female, NPT/BSP
    Two fluid ports are standard; a plug to seal the recirculation port is included.
  • Maximum Fluid Pressure: 600 psi
  • Air Connection Size: 1/8 Female NPT; 1/8 Female BSP adapter automatically included when fluid connection is BSP
  • Air Cylinder Pressure: Minimum: 30 psi; Maximum: 250 psi. For larger BJ tips, more pressure may be required to break seal.
  • Operating Temperature Range: -15 °F to 400 °F. Nylon Mounting Hardware: 250 °F MAX
  • Standard Materials:
    Body: Nickel-plated Brass or 303 Stainless Steel
    Internals: PTFE, Viton, 303SS
    Air Cylinder: Stainless Steel, Anodized Aluminum, PTFE, and Viton®
  • Fluid Seals: FDA-compliant Viton®
  • Air Cylinder: Single-acting spring extend type. Air pressure retracts the rod and allows flow through the nozzle.
    Removing air pressure extends the rod and seals the nozzle. Double-acting cylinder available upon request.
  • Frequency Rating: Up to 180 cycles/minute, with an appropriate solenoid valve (Cv=0.08 minimum).
