Spray nozzles are precision components designed to yield very specific performance under specific conditions


BASIC NOZZLE CHARACTERISTICS

Before considering how to optimize spray nozzle performance, lower maintenance requirements and/or extend nozzle life, you should spend a few moments reviewing the basic characteristics of your spray nozzles to verify that you are indeed using the best nozzle type for your application.

The reference chart that follows summarizes the performance that each nozzle type is designed to deliver. We have technical bulletins and technical support staff that can provide further assistance upon request.

whirl chamber-type hollow cone spraying water

HOLLOW CONE (WHIRL CHAMBER-TYPE)
General Spray Characteristics
Available in a wide range of capacities and drop sizes. Provides a good interface between air and drop surfaces.

Comments
The extensive range of capacities and drop sizes makes the hollow cone nozzle useful for a variety of applications where a combination of small drop size and capacity is required.

Spray Pattern:

Spray angles from 40° to 165°


deflected-type hollow cone spraying water

HOLLOW CONE (DEFLECTED-TYPE)
General Spray Characteristics
Utilizes a deflector cap to form an "umbrella" shaped hollow cone pattern.

Comments
Larger capacities can be used to flush or clean tube and pipe interiors and small tanks.

Spray Pattern:

hollow cone deflected spray pattern

Spray angles from 100° to 180°


spiral-type hollow cone spraying water

HOLLOW CONE (SPIRAL-TYPE)
General Spray Characteristics
Provides a hollow cone pattern with drops that are slightly coarser than those in other hollow cone sprays.

Comments
Provides high flow rate in a compact nozzle size. The one-piece design features maximum throughput for a given pipe size.

Spray Pattern:

hollow cone spiral spray pattern

Spray angles from 50° to 180°


full cone spraying water

FULL CONE
General Spray Characteristics
Provides a uniform, round and full spray pattern with medium-to-large size drops.

Comments
Provides full spray pattern coverage with medium-to-large flow rates. Some vaneless models and oval spray models are also available.

Spray Pattern:

full cone spray pattern

Spray angles from 15° to 125°


full cone  spiral-type spraying water

FULL CONE (SPIRAL-TYPE)
General Spray Characteristics
Provides relatively coarse drops in a full cone pattern with minimal flow obstruction.

Comments
Spray coverage is not as uniform as that from conventional internal vane type nozzles. Provides high flow rates in a compact nozzle size.

Spray Pattern:

full cone spiral-type spray pattern

Spray angles from 50° to 170°


flat spray tapered nozzle spraying water

FLAT SPRAY (TAPERED)
General Spray Characteristics
A tapered edge flat spray pattern nozzle that is usually installed on a header to provide uniform coverage over the entire swath as a result of overlapping distributions.

Comments
Designed to be used on a spray manifold or header for uniform, overall coverage across the impact area.

Spray Pattern:

flat spray tapered spray pattern

Spray angles from 15° to 110°


flat spray even nozzle spraying water

FLAT SPRAY (EVEN)
General Spray Characteristics
Provides even distribution throughout the entire flat spray pattern. Produces medium size drops. Ideal where high and uniform spray impact is required.

Comments
The thin rectangular pattern of this nozzle provides uniform coverage. In manifold set-ups, the nozzles are carefully positioned for edge-to-edge pattern contact. Designed primarily for high-impact applications.

Spray Pattern:

flat spray even spray pattern

Spray angles from 25° to 65°


flat spray deflected-type nozzle spraying water

FLAT SPRAY (DEFLECTED-TYPE)
General Spray Characteristics
Produces a relatively even flat spray pattern of medium size drops. The spray pattern is formed by liquid flowing over the deflector surface from a round orifice.

Comments
Large free passage design through the round orifice reduces clogging. Narrow spray angles provide higher impact, while the wide-angle versions produce a lower impact.

Spray Pattern:

flat spray deflected-type spray pattern

Spray angles from 14° to 153°


solid stream spraying water

SOLID STREAM
General Spray Characteristics
Solid stream nozzles provide the highest impact per unit area.

Comments
Ideal wherever a very high spray impact is required.

Spray Pattern:

solid stream spray pattern

Spray angles 0°


hydraulic fine mist atomizing nozzle spraying water

ATOMIZING (HYDRAULIC, FINE MIST)
General Spray Characteristics
A hydraulic, finely atomized, low capacity spray in a hollow cone pattern.

Comments
Used to produce finely atomized sprays when compressed air is not desirable.

Spray Pattern:

atomizng spray pattern

Spray angles from 35° to 165°


air atomizing nozzle spraying water

AIR ATOMIZING AND AIR ASSISTED
General Spray Characteristics
Atomization produced by a combination of air and liquid pressures. Air assisted nozzles feature internal impingement atomization to assist fine drop formation.

Comments
The most widely used nozzle group for producing finely atomized sprays in a wide range of capacities.

Spray Pattern:

air atomizing spray pattern

Cone and flat spray patterns
