Spray Equipment: Spray Nozzles 101

Posted by Sprayer Depot on Wed, Jun 29, 2016

Nozzles may be small, but they play a critical role in the application of chemicals. Learn all about spray nozzles.pngSelecting the proper size and type of nozzle is an essential step to determine the amount of spray applied to an area. Use the wrong nozzle, and you may over or under spray the solution which will result in an ineffective application.

A few questions that will help you make the best nozzle selection for your particular application include:

1. What's your application type? (i.e., agricultural, pest control, lawn & landscape, etc.)

2. What's the predetermined distribution pattern? (i.e., broadcast, banded, stream, etc.)

3. What's the recommended droplet size?

4. What type of nozzle material is needed to avoid corrosion?

Let's go over a couple of key elements you can apply to answer the questions above:

Application Rate

Consider nozzle orifice size, operating pressure, nozzle spacing and nozzle speed to determine the application rate. A couple of tips to keep in mind include:
  • The smaller the orifice, the smaller the droplet size
  • Small droplets are subject to more drift and evaporation than larger ones
  • Dense areas require higher pressure for the droplet to reach its target
  • Measuring pressure at the boom is the most efficient way to test actual pressure rate
  • Take into account the angle of the spray tips and their height to space the nozzles at an appropriate distance
  • The faster the speed of the application the less solution applied and vice-versa

Pattern Distribution

The pattern distribution should offer accurate coverage when using the appropriate nozzle. The three most common nozzle distribution patterns are:

1. Flat fan pattern nozzles: Ideal for broadcasting application, flat fan are the most widely used pattern nozzles. Hypro offers a wide selection of flat fan pattern nozzles; browse our extensive inventory by clicking here.

2. Cone pattern nozzles: Best suited for banded application but can also be used for broadcasting application. Cone pattern nozzles are particularly useful when spraying crops as they provide better coverage.

3. Flooding nozzles: Perfect for applications where wind-tolerant nozzles are needed. Use flooding nozzles when spraying at lower pressures with a large droplet to minimize drift.

Nozzle Material

Nozzles come in a wide variety of materials such as polyacetal, ceramic, stainless steel or PVDF. Depending on their use and spray solution, nozzles will wear out at different rates. Always check the label of the chemical solution to check for compatible nozzle material. Also, pay close attention to any specific cleaning or maintenance requirement to keep nozzles clean.

Hypro and TeeJet are among our most popular manufacturers of high quality nozzles. They also have many educational resources that can help make the selection process a bit easier for you. Check out these two simple selection guides that will help you identify the correct nozzle:

3 Keys to Selecting the Right Spray Tip

Posted by Sprayer Depot on Thu, May 28, 2015

hypro_spraytipSpray tips are important, but these small components happen to be an often-overlooked part of a sprayer. With so many options on the market it’s no wonder that you might feel overwhelmed with choices. However, the benefits of finding the right tip for your application will pay in spades in the long run. Determining which spray nozzle is best for your needs depends on a variety of factors, including the type of spray application and your sprayer equipment.

An appropriate spray tip can do the following:

  •       Reduces off target spray
  •       Provides more control to improve coverage
  •       Means you save money
  •       Best for the environment
  •       Means you complete your spray job faster

So there’s a reason why there are so many different types of spray tips in tons of sizes, capacities and materials. To get started, you should identify your needs. This first step will guide you to a narrower field of nozzle options. For instance, are you trying to reduce spray drift? Do you need a wide pressure range? What would you change about the nozzle you’ve used most recently? Do you want better coverage? Once you’ve identified your needs, then follow these three keys to selecting the right spray tip.

1. Determine Flow Rate (gpm): You’ll need to identify the application volume (gpa), travel speed (mph) and nozzle spacing in inches (w) to find the right flow rate. Your calculation may look something like this: 

Flow Rate (gpm) = Volume x Speed x Nozzle Spacing
                                                   5,940 

Check out the Hypro SprayIT Calculator – it’s a helpful reference guide, or TeeJet’s nozzle selection guide

2. Select the Right Nozzle: With that information on hand you’ll have a better idea of the type of nozzle needed and can follow the manufacturer’s chart to identify the model that will work best for your needs.

Keep in mind that nozzles come in different materials. Brass resists corrosion from corrosive chemicals, plastic will not corrode and resist abrasion, stainless steel offer good corrosion resistance and are best suited for high pressures, aluminum are easily corroded by some fertilizers, and ceramic are highly resistant to abrasion and corrosion.

3. Calibrate and Adjust: After you’ve installed the new spray tip, calibrate your sprayer. This determines the amount of spray volume applied per acre. Also keep in mind that when you’re on a job, the spray pressure output of you sprayer may differ from the charts. You can adjust for this by determining the amount of pressure at the nozzle and then subtracting or adding pressure from your main gauge to compensate and ensure that you’re getting the desired output needed.

Have other suggestions to selecting the right spray tip for your needs? Maybe you’re a fan of simply calling our Customer Service Technicians to determine the right product or perhaps you have a specific brand you prefer. Either way, we’d love to hear what work best for you. Leave a comment below.

Some of the top sprayer manufacturers, plus leading chemical manufacturers like BASF and Syngenta, are partnering with Hypro in developing spray boom components to meet the demands of today’s precision spraying. 

Nozzle Bodies
There is a certain amount of pressure lost when liquid flows through any spray component. This is "pressure drop". Hypro ProFlo nozzle bodies have the lowest pressure drop at any given flow in the industry, for instance 2.6 gpm with 5 psi pressure drop. This adds to system efficiency and supports faster field speeds. Other ProFlo features:

  • Single, 3, and 5 way nozzle bodies for wet and dry booms

  • Diaphragm check valves in EPDM or Viton

  • Reliable turret index provides positive shutoff between positions

  • Full line of nozzle body accessories (caps, barbs, adapters, clamps, etc.)

Express End Caps and Fittings
Air gets trapped in booms and causes the nozzle to actuate non-uniformly, resulting in under/over spraying of targets. Hypro’s unique Express End Caps and Fittings, designed for 1-inch stainless tubes, permit all the air to leave the boom, allowing uniform spraying. Clean-out ports eliminate “dead ends” on booms that accumulate unwanted chemicals. 

Spray Tips
Hypro has a full line of agricultural spray tips including fan, cone, flooding, plastic, ceramic, and a broad range of flow rates. Only Hypro offers:

  • Ultra Lo-Drift tips. The ULD, with an air induction fan spray, provides the best combination of drift control and coverage in the industry.
  • GuardianAir Twin. The GAT, with forward and rear air induction fans, is the best choice for high coverage targets and complex canopies.
  • The industry’s best spray tip selection tool. To use the SprayIT calculator, enter your spray parameters and Hypro will show you the available tip options.
  • The industry’s best mobile app for spray tips. From your mobile device enter your spray parameters and the chemical name and Hypro will show you the available tip options. Find it here on iTunes and here on Google PlayYou can also access the recommended spray quality for many popular ag chemicals andmatch the droplet size to Hypro spray tips.

Hypro’s Spray Nozzle Selection Simplified

Posted by Sprayer Depot on Wed, Oct 15, 2014

We’re always looking for ways to make spray nozzle selection easier and we’ve shared some tips of the trade in past posts right here on our blog. With new advances in technology and an ever-evolving line-up of options, we couldn’t resist sharing this Spray Nozzle Selection Guide and helpful information from our friends at Hypro.

Consider this. When selecting nozzles it’s easy to determine what droplet and flow rate you need, but what happens when the chemical you are spraying changes? Does that change the nozzle you should be using?

Hypro has developed a simple set of tools that will help steer you to the correct nozzle technology while considering multiple tank mix characteristics. The Spray Nozzle Selection Guide will walk you through a series of questions to identify the correct nozzle, including:

  • What and when are you spraying?
  • Are you using an adjuvant, and if so, what type?
  • In your chemical Contact or Systemic?
  • Is your primary concern drift or coverage?

Nozzle Selection Guide

From there you’ll determine which of six nozzles are best for your application. Choices include Hi-Flow and ESI Six Stream, which are best for Fertilizer Plant Nutrients. Those spraying Herbicides and doing Weed Control would be served best with the Ultra Lo-Drift, Guardian or GuardianAir nozzle types, according to the guide. Rounding out the bunch are the Insecticide/Fungicide Plant Health needs that are best suited by using the Guardian, GuardianAir or GuardianAir Twin nozzles.

Interested in more? Hypro’s Spray Tip Guide digs further into the subject, providing technical details to support your selection. Some of the topics covered include:

  • Why different nozzles should be used when changing what you spray
  • How do adjuvants effect nozzle selection
  • When does using a Contact or Systemic chemical change your nozzle selection
