What to Consider When Choosing the Best Backpack Sprayer
Before opting for the first hobbyist or professional backpack sprayer you see, take some time to familiarize yourself with the various product factors that might affect your final decision. Consider the pressure (psi), tank capacity, the type of liquid delivery system, and the type of pump that pressurizes the backpack sprayer.
Pressure
Pounds per square inch (psi) is the unit of measure identifying the amount of pressure a backpack herbicide sprayer can propel through its nozzle. The average for a backpack sprayer is around 70 psi, but smaller models can use as little as 40 psi and a commercial backpack sprayer may use as much as 150 psi.
Pressure is important to ensure your backpack sprayer operates effectively. Too little pressure will produce an uneven spray that reduces the effectiveness of its contents, while too much will prove excessive for a smaller yard.
If you have a large yard with many hard-to-reach spots, or you are a professional who works in many different-sized spaces, a sprayer with a psi rating of 70 or above is your best bet. For those with average-sized or smaller yards, a moderate rating between 40 and 70 psi is more than enough to spray your space.
Piston vs. Diaphragm
Backpack sprayers generally come in one of two types of liquid delivery systems: piston pump and diaphragm pump.
- A piston pump works by drawing liquid from the tank into an enclosed chamber on the upstroke and pushing the liquid out through the outlet valve or nozzle on the downstroke. Piston pump sprayers are more popular with the average homeowner because of their simple design, easy accessibility for repairs, and beneficial psi ratings.
- A diaphragm pump is designed for the safety of professionals who use potent pest control and weed killer chemicals. It is a sealed system that works by moving liquid from one side of a chamber to the other with a diaphragm so that one side is always full and one side is always empty. The diaphragm pump cannot produce the same pressure as the piston pump but is better suited to pros because it’s made of more chemically resistant materials.
Manual vs. Motorized
Backpack sprayers use an internal pump to draw liquid out of the chamber, through a hose, and out through a wand and nozzle. This pump can be operated manually or an electric backpack sprayer will often use a motorized system—the pricier option.
Manual backpack sprayers operate via a hand pump attached to the backpack chamber. Pumping manually for an extended period can cause muscle fatigue and pain, so while this style of sprayer is fine for smaller yards, once-per-season jobs, and the average homeowner, it’s less suited to professionals who have to spray for hours at a time. Manual backpack sprayers cost as little as $40 to as much as $150, on average.
Motorized backpack sprayers are powered either by battery or gas, with a battery backpack sprayer offering more versatility and a simpler setup. A motorized sprayer automatically pumps the liquid from the backpack chamber to the wand, requiring no physical work by the user. Intended for large projects and long workdays, a motorized sprayer (which can run between about $100 to $500) is a better choice for the busy professional who’ll rely on it daily.
Tank Capacity
Sprayers are available in a tank capacity range between 2 and 7 gallons. Carry smaller-capacity sprayers with a handle, and tote the largest tanks with a wheeled cart. A 4-gallon backpack sprayer is considered to be about average in size.
Sprayers that fall between these two size extremes are true backpack sprayers—light enough to carry on your back, but too heavy to lug around by hand. For typical jobs, such as fertilizing a lawn or spraying an insect infestation, a 4-gallon tank can do the trick for a yard between 5,000 and 10,000 square feet.
