Types Of Backpack Sprayers

When you are shopping for a backpack sprayer, it is essential that you take the time to learn about the different types. There are different types of pumps as well as different ways that the sprayer is powered and these features will determine the best use for that particular product.

Diaphragm

If you are looking for a backpack sprayer to use in a professional capacity then you will probably find that most models come with a diaphragm pump which is designed for improved safety when working with commercial pesticides and weed killers. This type of system is sealed and moves the chemicals from one side of the chamber to the other. This means that one half will always be empty while the other half is always full.

While this type of pump won’t be able to produce as high pressure as pistons pumps (which we will discuss shortly), they are beneficial to commercial users as the materials are typically much more resistant to the potent chemicals.

Piston

The second type of pump that you will commonly find on a backpack sprayer is the piston pump. This works by drawing the liquid that is inside the tank into another chamber which is enclosed as the piston makes its upstroke. As it comes back through the downstroke, the liquid is then forced out of the nozzle and onto the area that you want to spray.

This type of backpack sprayer is a common choice for domestic users because they are much simpler and easy to use. Moreover, they don’t require a lot of maintenance and anything that does need to be done can be done without much hassle. You’ll also benefit from decent psi ratings which are often adjustable.

Battery Powered

Like many outdoor tools, a lot of backpack sprayers are operated by a powerful lithium ion battery. These tools typically work by using one of the aforementioned pumps inside the device which then draws out the chemicals and expels them through a wand, hose or nozzle. Now, there are a number of manual options, which we will explore shortly but battery powered backpack sprayers are very effective, albeit a little more expensive.

There are also gas powered sprayers although these require a lot more upkeep and especially for homeowners, this can be a little much. Battery powered sprayers offer great versatility and don’t require anywhere near as much maintenance. If you don’t want to have to exert any physical strength when using your sprayer, these battery versions do all the work for you.

They are also a great choice for those working in a professional capacity as they won’t wear the user out over the course of the day.

Manual Sprayers

Motorized backpack sprayers are a very convenient option but there is still a place on the market for the manual backpack sprayer. However, you should keep in mind that this type of device requires the user to manually pump the liquid out which can be tiring when you are working for a long time. For this reason, we wouldn’t suggest these tools for large areas or for those working in a commercial setting.

However, if you have a small yard and just a little bit of work to do, these affordable sprayers are ideal. In some cases, you can find them for as little as $40 and even at the top end of the budget, you wouldn’t expect to pay much more than $150.

What Is a Backpack Sprayer Used For?

If you are going to invest in a backpack sprayer then the chances are that you are going to want to know how to use it correctly. The great thing about these pieces of equipment is that they are so versatile. They can be used for a lot of different things although their main function is to apply herbicides around the garden.

If you have a lot of weeds, a backpack sprayer will come in very handy and will save you a lot of time when it comes to tackling the problem. What’s more, they can also be used in pest control and for applying things like fertilizers to trees, shrubs and a variety of other plantlife.

You may have seen professionals using a backpack sprayer and thought that these are the only people that benefit from them. But this couldn’t be further from the truth. In reality, anyone can own a backpack sprayer and make their lives easier when it comes to gardening.

If you have ever used a handheld sprayer then the backpack version is very similar in terms of how it works. The key difference is that these pieces of equipment are much bigger and can hold a lot more chemicals at once making them more suited to larger areas.

You could be forgiven for thinking that a backpack sprayer would be tiresome to use and very uncomfortable. After all, you’ll be carrying all of that liquid on your back. But this is another common misconception. Most of the best backpack sprayers are fitted with incredibly comfortable padded shoulder straps that make carrying the sprayer super simple. Plus, you don’t have to worry about carting a hefty container around the yard with you.

What To Consider When Choosing A Backpack Sprayer

When it comes to choosing the best backpack sprayer for your needs, there are a host of things you will need to consider. Before you rush out and buy the first product you stumble upon, take a look at our handy buying guide.

Warranty

One of the first things you should know about your potential new sprayer is whether it comes with a good warranty and what is covered. You would typically expect to have a warranty of at least one year but some manufacturers are so confident in their product that they offer more than this. The longer the better and you’ll have excellent peace of mind.

It is also worth keeping in mind that if you choose a battery backpack sprayer then the battery may come with a different warranty which may be shorter than that of the equipment itself. This is common practice but something that not all buyers are aware of.

Pressure Consistency

When using a backpack sprayer you will need to think about the pressure it uses to force out the chemicals. This is measured in pounds per square inch, commonly shortened to psi. In general, you would expect a decent backpack sprayer to be around 70psi but a lot of models feature adjustable pressure which can range between 40 and 150psi.

This is an essential feature to look at as it will tell you how effective and powerful the tool will be. If there isn’t enough pressure then the spray won’t be even and you won’t get even coverage. However, if the pressure is too high then this may be too much especially in a smaller setting.

It is also important to look at how consistent the pressure of the spray is. The last thing you want is a sprayer that is unable to maintain a steady flow because this will result in less than even coverage.

Safety

Using a backpack sprayer should be relatively safe when done properly. There are some obvious safety tips such as ensuring that you use the correct protective gear and to avoid getting chemicals onto your skin. You should also take care to quarantine the treated area and to avoid allowing pets into it until everything has dried.

However, it can be useful to look for features on the sprayer that improve its safety. Things like a no leak tank will prevent chemicals from escaping and ending up on you or in places that you don’t want them.

Cost

If you are in the market for a battery powered backpack sprayer then you must be prepared to pay more for this. Naturally, the technology that has to go into creating this type of equipment is more than what goes into the manufacture of manual sprayers so the cost goes up.

It can be tempting to go for a manual tool because of how affordable they are but you have to consider the extra work you’ll need to put in. This isn’t such a big problem if you only have a small area to work on but for anything significantly bigger, it’s probably worth making the investment.

Ease of Use

The last thing that anyone wants is a tool that is difficult to operature. You should look for user friendly features like simple controls that don’t require in depth training to learn how to use. You might also consider things like how easy the sprayer is to clean and maintain as nobody wants to spend hours looking after their equipment.

One of the most important features when looking at ease of use is how wide the opening is for pouring in your chemicals. The wider this is, the easier it will be to fill. It can also be useful to have a translucent tank which allows you to see how much you are pouring in.

Motorized or Manual

We have already looked at the difference between motorized and manual backpack sprayers but it is important to to emphasise how crucial it is to choose the right type. Battery sprayers will do all of the work for you, eliminating the need to manually pump out the liquid which, when done for a long time, can be tiring.

But a great thing about having the sprayer work for you is that you’ll usually achieve much more uniform results. Most battery sprayers are very consistent.

In addition to this, you should keep in mind that most modern powered sprayers use the latest technology meaning they are very efficient. In days gone by, it wasn’t uncommon for manufacturers to simply upgrade manual sprayers with a battery. But that is rarely the case any more.

Of course, a manual sprayer is ideal for people who are working on a smaller area and will certainly save you money.

Holding Tank

Normally, you will find that a backpack sprayer comes with a tank capacity of 4 gallons. But there are other options out there that tend to range between two gallons and seven gallons. The size of the area you want to cover will determine what the best tank size for you is.

But let’s assume that you have gone for an average four gallon tank; you would easily be able to cover an area between 5000 and 10,000ft² which is typically more than enough for the average garden.

Harness, Straps and Padding

Your backpack sprayer might be made from lightweight materials but once it is filled with liquid, it may become quite heavy. Carrying it on your back is much easier than carrying it in your hands, but it will put pressure on the shoulders without the right type of harness or strap.

You should look for one that is strong and takes a lot of the weight. Another important feature to look out for is padding. This will eliminate any discomfort and make the sprayer much more pleasurable to carry.

Spray Nozzle

Your backpack sprayer will likely come with a selection of nozzles that can be used for different applications. Typically, you will find that this ranges between two and four nozzles, but it can vary between manufacturers.

It’s also worth looking at whether the nozzle is easy to adjust in terms of pressure and whether it can be swivelled to alternate positions for easy application.

Applicator Wand

The applicator wand or hose on your backpack sprayer determines how much reach you will get from the device. Some commercial models come with very long hoses that allow you to spray up to 20 feet ahead of you.

You should also look at the materials from which the wand is made. Things like brass and stainless steel are excellent as these are very resistant to the chemicals you will be using and will last much longer.

Final Thoughts

If you have a garden and want to make light work of applying liquid chemicals then using a backpack sprayer is the best bet. These tools allow you to cover a large area in a timely manner and deliver exceptionally even coverage.
