Maintaining and Servicing Your Roller Pump

Posted by Sprayer Depot on Mon, Nov 16, 2015

Your pump will last longer and perform at its best if you keep up with routine service. How often should you maintain your pump will depend on how often you use it and the type of liquid being pumped. However, there are general guidelines that the manufacturer recommends should be followed to properly maintain your pump.

Hypro Roller Pumps are some of our most popular pumps. They are used across different industries such as pest control, weed control, horticulture and other agricultural applications.

For those of you unfamiliar with this type of pump, Hypro Roller Pumps come in three different materials: Cast Iron, Ni-Resist, and Silver Series XL. They are compatible with a variety of liquids and chemicals, require no check valves and are budget friendly.

Before performing any type of maintenance make sure you follow these safety measures:

  • Pump should be disconnected from its electrical, hydraulic, shaft driven, or gas engine power source.
  • Do not perform service or maintenance to the pump, or attached components, until the pump unit is below 109°F (43°C). 
  • When handling Hypro pumps, wear steel-toed shoes and protective gloves in order to protect your feet and hands. Eye protection should also be worn.
  • Any hazardous liquids should be disposed of in a manner which complies with local and national regulations. Never dump fluids onto the ground.
Cleaning your roller pump after every use is easy and will prevent downtime. Flush the pump with a neutralizing solution depending on the liquid just pumped. Follow this with a clean rinse using fresh water. Don't forget to wipe down the pump after each use to prevent deposits from forming and damaging it.

When you are ready to store your pump for a long period of time, make sure to drain it thoroughly. Open any drain plugs, remove the suction hose and blow it dry with air. An antifreeze/rust inhibitor should be injected into the pump before both ports are plugged and the pump is stored. Plug all ports to keep out air until pump is used again.

Your Sprayer Needs an Oil Change Too

Posted by Sprayer Depot on Wed, Oct 22, 2014

We get it. There’s a ton on your plate and often some maintenance practices, like changing the oil in your sprayer, can fall by the wayside. Our technicians often get asked how often we recommend changing the oil in a pump crankcase. Of course, we defer to manufacturer recommendations, but thought it might be helpful to run through the process with one of our more popular pumps, the Hypro D30 Diaphragm Pump, especially as the sprayer season winds down.

For those of you unfamiliar with this product, Hypro diaphragm pumps come with oil in the crankcase. Unlike your vehicle, accessing oil in the crankcase take a little more effort.

The manufacturer recommends changing oil after 40 hours of break-in operation and then every three months or 500 hours, whichever comes first. So this means that you should change the oil in this particular model at least four times a year, if not more. Now Hypro recommends using its own brand of oil for this model - Hypro Oil (part number 2160-0038) is specially formulated, high-grade, nondetergent, SAE 30 weight oil designed to prolong pump life. 

Now that we have that covered, let’s talk about the three steps to changing the oil in your spray pump.

Step 1. After you’re done with your sprayer for the day, flush the pump with clean water.

Step 2. To drain the oil from the pump, remove the oil drain plug and rotate the shaft until the oil stops flowing out. If you have time to open the pump and inspect the diaphragms, now is a good time, but not mandatory.

Step 3. To fill the pump with oil, slowly pour the oil into the sight tube while turning the pump shaft. Turning the pump shaft purges all the air out of the crankcase. So you won’t have to deal with air bubbles or a less than full amount of oil. If you do decide to replace the diaphragms, always change the oil.

One quick note, for winter storage, which we’ll get into later here on the blog, or if you encounter freezing conditions, flush the pump with a 50/50 mixture of water and antifreeze. 

Lastly, keep in mind that most manufacturers recommend changing the oil in your pump every year, if not sooner. We’d actually go as far as to say that it’s highly recommended that the oil be changed at both the start and the end of the sprayer season so that any contaminants entering the crankcase can be removed before sitting in the pump all winter and that you get rid of any buildup from the off season.

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?
Hypro's Spray Nozzle Guide

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
If you still have questions regarding what spray nozzle you should use, contact one of Sprayer Depot's knowledgeable Customer Service Technicians.

How To Build the Perfect Custom Sprayer

Posted by Sprayer Depot on Fri, Sep 05, 2014

Kings Sprayer 100/50 Dual Tank Skid Sprayer

When we say we know sprayers, it’s true. Our team builds more than 500 custom sprayers each year for customers looking to modify or completely reconfigure the makeup of this important tool. After all, you don’t have to settle for less than perfect in the sprayer world. Just turn to our Sprayer Depot knowledgeable customer service technicians with your ideas and < bam > the perfect custom sprayer is born. Here we’ll take a look at some of the common modifications to a few of our best selling sprayer models from Kings Sprayers.

You might be wondering if Sprayer Depot can modify one of the existing sprayers manufactured from Kings Sprayers. In a word, YES! Whether it’s adding more hose, swapping out the pump, or modifying the entire unit to your specific needs, Sprayer Depot can make it happen. We talked to operations manager David Herrera who mentioned “one of our biggest strengths is that we can get creative to solve space issues by creating custom frames and thinking outside the box.” Let’s take a closer look at a few scenarios as described by David:

One common customization is the dual tank setup (pictured above). Sometimes customers want two tanks so they can have chemicals in one tank and fresh water in the other, or another common scenario is having a need to spray two different chemicals while out on the job. We can make that happen within almost any parameter needed.

Another unique customization we created at the request of a customer is depicted in the same image above where you’ll notice that the hose reel is turned to the side. This is popular with the skid sprayer units in particular because the skid sprayer is usually in the bed of a pickup truck. It can be more convenient for the operator to have the hose dispatched from the passenger side when spraying lawns and shrubs. 

Gator Kings SprayersAnother example is  this custom Gator Kings Sprayers model. This skid sprayer unit fits into the back of a Gator utility vehicle. We had a customer request for a 100-gallon tank with a specific pump, engine, and hose reel. Given the standard way we build our skids, there was no way we could fit what the customer wanted in his Gator. So we got creative by using a low profile tank and designed a custom frame so that all of the components could be mounted above the tank. This is one of the most direct examples of how our team can creatively solve a problem a customer might have encountered with a standard off-the-shelf sprayer.

Below are a few of the most common modifications that can turn a stock sprayer into a custom model ideal for your needs:

  • Change the manual hose reel to an electric version
  • Add more hose to the hose reel
  • Change the standard spray gun to something else
  • Swap in a larger tank
  • Change the gas engine to electric start
  • Modify the orientation of the tank on the frame
  • Change the sprayer pump to a different manufacturer’s pump
  • Add another line on the suction side

So, what modifications would you love to improve your sprayer?

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.

6 Reasons Why You Need Drift Control Spray Tips

Posted by Sprayer Depot on Wed, Jul 16, 2014

Hypro air inducing spray tip


Spray tips
are the smallest and most overlooked components of a sprayer. Drift control spray tips use air induction to produce air filled droplets, which dramatically reduce drift compared to conventional tips. Here are the benefits: 

  1. Reduce off target spray. Your neighbors don’t want your ag chemicals on their property.
  2. Improve efficacy. It is estimated that 30% of conventionally sprayed droplets drift off target, land on the ground, or evaporate (leaving the active ingredient inert). Reduce that drift to 2% and achieve better results.
  3. Improve coverage. Air filled droplets stick to their target while conventional droplets may bounce off. When the air bubbles break the surface tension of the droplet, the spray material becomes more dispersed on the target.  
  4. Improve spray quality. The chemical label shows a droplet size category, which can vary from extremely fine to ultra coarse, at which the product must be applied for optimum results. Air induction tips produce more consistent droplet diameters than conventional tips.
  5. Save money. With improved efficacy and coverage you may require less chemical and less water to finish the job. With improved efficacy and coverage likely you will only need to spray once, saving money and time.
  6. Be environmentally responsible. Keep herbicides, pesticides, fungicides, and fertilizers confined to their targets and out of drinking water supplies and the aquifer.

Before you buy any spray tips, it is also important to know:

  1. Your spray technique: broadcast or banding
  2. Sprayer speed (in mph)
  3. Tip spacing (20 inches, etc.)
  4. Application rate (from chemical label)
  5. Spray tip flow rate (GPA or GPM)
  6. Spray pattern: flat fan or cone
  7. Spray quality (fine, medium, coarse, etc. from chemical label)

Armed with this information, use the Hypro SprayIT Calculator to select drift reduction tips. Hypro has designed this online calculator to make it easy to select the proper spray tip for your application. Given the information we just covered, all you need to do is select the type of application and input your specific application data and the calculator with do the rest.
