3 Reasons Why a Strainer Is an Important Part of Your Sprayer

Posted by Sprayer Depot on Wed, Dec 16, 2015

Recently, our Customer Service Technicians have fielded a few calls regarding clogged strainers. While it may seem like a basic sprayer maintenance issue, it's often overlooked by even large companies with fleets of trucks and multiple sprayer units. 

So, we've updated this helpful post to emphasize the importance of good spray equipment maintenance.

Clogging can cause a number of expensive problems on your sprayer. The fix to this common issue is Clogged_Strainer-filter.jpgsimple and economical: properly install and service your strainer. The strainer in your sprayer is one of the easiest parts to maintain, however it's probably the most overlooked one. A clean and properly sealed strainer will allow proper flow to the pump and contribute to a longer pump life. For most applications, a standard Buna Gasket is adequate. However, if you find that you are replacing the Buna Gasket frequently, a Viton Gasket is a more durable option. 

Why is such a small part on your unit so important? There are three main reasons:

 

  1. Maintains consistent fluid circulation throughout the pump

  2. Keeps nozzles from clogging 

  3. Helps achieve optimal sprayer operation

Prevent Clogs
 
Some of the main reasons why a strainer gets clogged include: (1) incorrect mesh size; (2) lack of maintenance; and (3) insufficient consideration for the liquid that getting sprayed (fertilizers require a larger mesh strainer than water based chemicals). When shopping for strainers, pay close attention to the mesh size. It generally ranges from 10-200 and the higher the number the tighter the mesh. On most agricultural and pest control sprayers the recommended mesh size is 16-30. We manufacture all of our Kings Sprayers with a 20 size mesh screen. However, depending on your application and the type of liquid being sprayed you may need a different size. If you need a recommendation just let one of our Customer Service Technicians know and they will fit your sprayer with the appropriate mesh. 
 
Cleaning the strainer should be done after every use. We get it, after a hard day's work you are ready to put the sprayer away and head home. But taking 5 minutes to flush it out will pay off in the future. We've seen it before, many customers have brought their sprayers to our service department for a repairafter they've spent hundreds of dollars replacing every other part in an attempt to figure out why there's a loss of pressure. The first thing we typically check is the strainer, and we often find it clogged like the one pictured above. 
 
Clean Your Strainer
 
No need to remove the strainer from the line in order to clean it. Simply unscrew the bowl from the cap and take out the screen. Next, flush any debris and sediment from the screen. Finish up by reassembling the strainer by first fitting the screen to the flange in the bowl. Hand tightening the bowl provides a sufficient seal.
 
Popular Strainers

Strainers come in all types of materials, from nylon to poly, and even aluminum. Their shapes also vary, with "T" strainers being the most popular styles and "Y" strainers coming in a close second. Some of our best sellers include:

Sprayer Maintenance FAQs

Posted by Sprayer Depot on Mon, Jul 20, 2015

PumppicsOur savvy Customer Service Technicians handle many calls throughout the day, many of which are inquiries from customers regarding how to properly maintain their sprayers in top-notch condition. For this reason, we have put together the most Frequently Asked Questions (FAQs) to help you take care of your equipment:

Q: When should I replace my spray tips? 
A: If you notice a change in flow rate or a change in pattern distribution then this might indicate that your spray tips need to be replaced. You should replace your spray tips immediately if they are worn out or damaged.

Q: How often should I flush my pump?
A: After every use, especially if you are using herbicide or other harsh chemicals.  Flush the pump using clean water.

Q: How do I know when my strainer needs to be cleaned?
A: If you notice a loss of pressure or a drop in flow rate then you may have a clogged strainer that needs to be cleaned. However, you should never wait until that happens, so it is advisable to clean it once a week depending on how often you spray. Check out our 3 Reasons Why You Should Check Your Sprayer.

Q: How often should I perform an oil change? 
A: Please follow your specific pump's manufacturer recommendations.

Q: When should I calibrate my sprayer?
A: You should calibrate your sprayer at least once every season. For more information on calibrating your sprayer please check our Step-By-Step Sprayer Calibration Guide to get you started.

Q: I am using a diaphragm pump, when should I replace the diaphragm?
A: Every 500 hours or every 3 months, whichever comes first.

Q: Should I also check my pump's valve?
A: Definitely! If you are replacing the diaphragm it is the perfect opportunity to also check the valve and replace it if necessary.

There are also a few other things you should make a habit of checking as part of your sprayer maintenance:

Check

  • Hoses for any cuts, damage or bends
  • Nozzles to make sure they are clean
  • Tank for any damage or rupture
  • Pressure switch for any leakage 
  • Boom spacing
As always, we are here to help you so don't hesitate to contact us if you have any questions!

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.

10 Steps to Obtain Optimal Sprayer Performance with a Diaphragm Pump & Hose Reel

Posted by Marketing Manager on Wed, Oct 17, 2012

Contributed by guest blogger:  Mark Techler, Techler & Associates

Obtain optimal sprayer performance with a diaphragm pump and hose reel by following these guidelines:

To ensure proper hook-up of diaghragm pump and hose reel, see diagram below

  1. Place the outlet fitting in the lowest point in the tank, or in the sump
  2. Connect a ball valve to the outlet tee (or elbow) so you can turn off the flow in case you need to service the pump or check the line strainer
  3. Include a line strainer between the tank and the pump to prevent debris from clogging the pump, relief valve, gun and nozzle
  4. The tank outlet fitting, elbow, suction line and strainer should be one pipe size larger than the suction port of the pump; The suction line should be reinforced so it does not collapse, but remains flexible so it absorbs pulsation (A clear suction line helps you see air bubbles if there is is air entering the system)
  5. Even though diaphragm pumps prime well, try to posititon the pump lower than the tank for gravity feed
  6. Most diaghragm pumps include a "control unit" consisting of a relief valve, multiple discharge ports with ball valves, and a pressure gauge (It can be mounted on the pump or remote mounted - If a remote mount is used, do not put a shutoff valve between the pump and the control unit)
  7. Connect the relief valve bypass port with an unrestricted line to the top of the tank, venting to atmospheric pressure - DO NOT PUT A SHUTOFF VALVE IN THIS LINE OR CONNECT THE BYPASS LINE TO THE AGITATOR - Restrictions may prevent the relief valve from bypassing properly and may result in damage to the pump
  8. Connect one of the discharge lines to the agitator(s); It's okay to use a ball valve in this ine to throttle the flow
  9. Connect one of the discharge lines to the inlet swivel on the hose reel; It's okay to use a ball valve in this line; Do not use hard plumbing when connecting the discharge line to the hose reel swivel
  10. Connect the spray gun
