What is a Backpack Sprayer?
Anyone who spends time in their yard or wants to ensure their outside space remains healthy and weed free needs a backpack sprayer. The fact is, this is quite a versatile tool. In addition to providing you an efficient and fast way to stay on top of your gardening maintenance tasks, these sprayers can also be used for various household tasks, such as cleaning your home, boat or car, or even applying a new layer of varnish to your deck. It can apply fertilizer to small spaces or treat a large area of plants quickly.
Backpack sprayers offer you a modern and no-mess, no-hassle approach to household maintenance and gardening tasks. This tool lets you apply pesticides or fertilizers quickly and avoids having to touch the chemical or undergo an in-depth cleanup process when you are done.
Basic Parts of the Backpack Sprayer
Now you may wonder exactly how a backpack sprayer works. The name is self-explanatory. These sprayers are compact, hands-free units that are carried on the back. There are five main parts that make up the sprayer, which include:
Tank: Typically made of polyethylene plastic, the tanks are resistant to chemicals, UV protected and durable. The most important aspect of your tank is that it does not leak.
Works by pulling liquid out of the tank and sending it into the pressurized tank, where it is held until you squeeze the lever on the wand.
The elongated shaft that lets you channel the liquid and spray it where you need it to go. You’ll want to make sure it fits comfortably in your hand, and the spray handle works easily.
This determines the pattern and flow of the spray, and most sprayers come with several types of nozzles. This will allow you to use the sprayer for a variety of applications, from a wide sweeping spray to more pinpointed streams for edges and such.
Harness or Straps
Since a backpack sprayer is designed to be wearable, there is a harness or straps attached that fit over your shoulders and chest to ensure the weight is distributed evenly. This is one of the biggest benefits, as carrying a large pump sprayer can become extremely tiring and cumbersome.
The majority of backpack sprayers can reach between 15 and 95 psi of pressure. However, there are commercial grade options that can provide up to 150 psi.
The pressure delivered is going to vary from one model to another, and one of the most important things to remember is that the pressure inside the tank will remain consistent and the liquid will spray continually until the trigger on the wand is released.
Another important thing to keep in mind is that, depending on the type of unit used, the pressure is going to decrease gradually as the tank becomes empty.
How to Choose the Right Backpack Sprayer
In addition to the basic components listed above, backpack sprayers are either operated by a diaphragm or piston pump.
Piston Powered Backpack Sprayers
The piston pump sprayers are easy to recognize because they use an up and down motion and have a chamber located inside the tank. They typically provide good pressure, approximately 90 psi. When the lever is pumped, it creates the pressure, forcing the liquid into the wand so you can spray what you need to disperse.
This type of sprayer is more affordable, but they are not suited for use with extremely abrasive chemicals, since these types of chemicals may destroy the piston.
A diaphragm sprayer is usually the more costly option and works in a similar way to piston pumps, without the internal cylinder. The pumping of the handle will move the diaphragm and create the pressure. These sprayers are more resistant to chemicals, and you can use liquids and powders in this type of sprayer. A diaphragm pump provides you with faster pressure when it is needed, but it may require more maintenance.
How do you know when to purchase a piston sprayer vs. a diaphragm unit? If you’re doing standard on-ground weed spraying that doesn’t require extremely high psi, a diaphragm unit will work just fine. If you have lattice work or other areas that require overhead spraying, a piston pump will allow you to get the higher pressure you need for an overhead application, more quickly.
Motorized or Manual Backpack Sprayers
When it comes to a backpack sprayer’s operation, there are two options – motorized or manual.
Manually Operated Sprayers
These are the most common types of backpack sprayers and require that you operate the hand pump. After you pump the handle, the pressurized liquid will be forced into the wand and made ready for spraying. These are affordable but can cause hand fatigue if you are going to be using them for a long period of time.
If you have a large space to treat, then using a motorized model that has a powerful battery is going to help you get the job done in a hurry and relieve the pressure from your hands because you won’t have to keep pressure on the handle at all times. Even though these sprayers are going to make the job easier and faster, they are more expensive and heavier and will require more maintenance over time.
Comfort and Safety
There are quite a few features offered by modern backpack sprayers that help to reduce cases of fatigue. Some feature adjustable and padded straps or tanks that are contoured providing a better fit. Look at comfort and safety features provided before choosing a backpack sprayer, since this will impact your overall experience with the device.
Repair Needs and Durability
The majority of quality sprayers will have tanks that are made out of high-density polyethylene, with the additional benefit of UV protection. If you are planning on fertilizing or having to handle large pest control jobs, you need a sprayer that won’t leak all over you. Try to find industrial strength hoses with seals that are leak-proof and chemical resistant.
A Lockable Shut-Off Mechanism
The lockable mechanism for shutting off the wand is typically installed on the backpack sprayer handle. This is a feature that can help you easily control the release of the chemicals or liquids and then keep them from dripping if you don’t want them to.
Improved Harnesses and Shoulder Straps
A quality harness and shoulder straps can make the home maintenance and gardening chores much easier. While most backpack sprayers are extremely lightweight, they can be much heavier when the tanks are filled up. If you see a sprayer that has adjustable padded waist, chest and shoulder straps, then it will make it more comfortable to wear for extended periods of time.
