Do This One Thing To Eliminate Half of Your Spray Equipment Problems

Posted by Sprayer Depot on Fri, Sep 22, 2017

At Sprayer Depot, we hear about a lot of different issues that can affect the proper functioning of sprayers. The most common issue however, is one which is easy to prevent and one of the simplest to fix: a clogged and neglected strainer. Before we discuss the steps to take to ensure that your strainer is in tip top condition, lets briefly go over the reasons why the strainer is such an essential part of your sprayer and its optimal functioning. 

What Does The Strainer Do?

The strainer is a basic component which helps to ensure that hypro_line_strainer-resized-600.jpgyour sprayer pump works efficiently. When properly sealed and maintained, it allows the fluid to flow freely by its three basic functions:

  1. The strainers main function is, as its name implies, to strain larger and smaller particles in the liquid from entering the pump, the flow meter, and other parts of the sprayer. 
  2. The strainer provides proper fluid circulation throughout the pump. 
  3. The strainer prevents the clogging that may occur over time when the large particles enter the other sprayer components. 

Strainer Screens and Strainer Types

Every strainer uses a mesh screen to filter out the unwanted particles and most of time, this is where we find problems with the strainer.  It is very important to use the proper size screen for your particular strainer and fluid application type.  The mesh size refers to the number of squares per inch of screen (for example, 12 mesh has 12 x 12 squares per inch of screen). In addition, using the proper kind of strainer for your application and sprayer is important.  There are two main types of strainers which we carry at Sprayer Depot and they are:

  1. Y-Style Strainers - These can vary in size from 1/2" to more than 12", are corrosion resistant, lightweight, and are commonly made of polypropylene.  Our Banjo Y-Strainers are one of our most popular strainer styles and available with several mesh sizes ranging from 12 to 80 mesh. 
  2. T-Style Strainers - Typically more compact in size than other strainer types, T-Style strainers are easy to check for clogs.  For high pressure or suction applications, we recommend the Hypro Nylon-line Strainers or the wide selection of Banjo T-Strainers we carry in polypropylene or poly/ stainless steel. The Banjo Poly T-Strainer Clear Bowl line have clear bowls that allow for quick and simple visual inspections for debris without disassembly. We also carry a complete line of TeeJet strainers and components including the TeeJet aluminum head and nylon bowl styles.

Basic Maintenance of Your Strainer

Proper maintenance of your sprayer unit requires both the use of appropriate mesh screens for your application and fluid type as well as regular inspections and cleaning of your strainer.  Mesh screens that are not designed to filter out particles for your fluid will be ineffective in preventing the ideal flow of liquid.  The recommended mesh size for most pesticides and other agricultural uses is between 16-30 but keep in mind that fertilizers and other chemicals require a larger mesh size screen than water based fluids. 

Inspecting and cleaning the strainer is very easy, takes only a few minutes and can save you both time and money.  The strainer should be inspected and cleaned after every use.  It doesn't require removal from the line but can be flushed by unscrewing the bowl from the cap and taking out the screen.  Once all sediments and debris have been flushed off the screen, you can simply reassemble by replacing the screen to the flange in the bowl and then tightening the bowl back onto the cap.  

Another helpful tip is to maintain your inventory with extra strainers, screens and gaskets.  This could save you many hours of wasted productivity time, especially since these items are very inexpensive components to purchase ahead of time and keep on hand for when they are needed! If you have any questions regarding the proper strainer type, mesh screen size, or any other inquiries about your sprayer needs, we're here to help.

Strainers: A Sprayer Companion

Posted by Sprayer Depot on Fri, Jul 18, 2014

One piece of equipment that is often overlooked is the strainer. Here we will dive into the importance of the strainer, or, as it is sometimes referred more simply, filters or screens. No matter what you call it, strainers are very important to reduce clogging, excessive erosion of spray tips and consistent fluid circulation of your sprayer equipment. As the name alludes, this part strains or filters debris to ensure even uninterrupted flow. 

To better understand the variety of strainers used on sprayers, we’ll discuss the most popular types of sprayer strainers used and review what strainer numbers mean.

Types of Strainers

Y strainer for sprayer equipmentShaped like the letter Y, the Y strainer is used in various agriculture and industrial liquid flow applications where the amount of debris that will be filtered is small. Often lightweight and made of polypropylene materials, the Y strainer is corrosion-resistant. Its cylindrical shape is very strong and meant to accommodate high pressures. These parts do have pressure ratings so make sure you choose the one that’s suitable for your sprayer system.

The T strainer is also shaped like its namesake, the letter T, but this part has a larger holding capacity so depending on its application it will go longer between cleanings. With the T strainer there is the option of purchasing the part with a clear T strainer with clear bowl for sprayer equipmentor white bowl, where the clear bowl offers the advantage of easy visibility to check for debris or chemical build-up. T strainers are good at trapping large particles and offer dozens of configurations, including self-cleaning strainers, designed for simple and quick cleaning and maintenance.

Built-in strainers, or tip strainers, prevent debris from entering the orifice or vane and can be used with a variety of standard and quick-connect flat spray, full cone, hollow cone and fine spray nozzles. These are used in conjunction with another type of strainer and filter out finer particles as a sort of last stop.

In general, most sprayer operations can benefit from adding line strainers or integral nozzle strainers. Though if you’re relying on tip strainers alone and these parts begin to plug frequently it may be necessary to add a single line strainer between the pump and the nozzle. From our experience, it’s much easier to clean a single strainer on the main line coming from the pump than to clean all of the individual tip strainers.

The Numbers

Strainer numbers represent the number of openings per square inch. The size can range from 10-200 mesh where high mesh numbers have smaller openings and result in a finer screen than low mesh numbers. So a 50 mesh means the strainer has 50 openings per inch. In general 100 mesh tip strainers are required for individual tips with a flow rate below 0.2 gallon per minute (gpm), 50 mesh between 0.2 and 1 gpm, and no strainer over 1 gpm. There are various strainer to sprayer tip combinations to provide the optimal psi, but for the sake of time we’ll save the topic of pressurization for later.

In considering the right size for your needs, keep in mind that the main strainer, often called inline or suction strainer, should be the same size or larger than the last strainer on the sprayer pump or boom. Though you don’t need to run strainers on each nozzle as long as you strain the water either into or directly out of all nurse tanks, have a main product strainer on the sprayer, and one strainer for each boom section of the sprayer. When in doubt, call the experts.

That’s not all. You also need to consider the type of product you’re spraying because fertilizers need a larger strainer than water based chemicals.

All in all, the strainer in your sprayer is one of the most important parts, but also one of the easiest to maintain. A clean and properly sealed strainer will allow proper flow to the pump and contribute to a longer pump life.

What's in YOUR strainer?

3 Reasons to Check your Strainer

The  strainer is one of the easiest parts of your spray equipment to check and maintain.  It's easy to access and it just takes a few minutes to check.  However, it's also one of the easiest parts to forget:  It's often overlooked because of its simplicity. All sorts of things can get caught in the strainer and keep your equipment from working at full capacity. Chemical build-up, leaves, frogs (this is more common than you may think), and other debris are common culprits.

Another reason to check the strainer regularly is to check the integrity of the mesh. Make sure there are no holes or rust. In addition, check the seal to make sure it is still pliable.

When checking your strainer, make sure the equipment is not under pressure and the valves are off.

 Clear Bowl "T" Strainers
