FAQs

1. How far do backpack sprayers spray?

Maximum up to 30 - 35 feet

This varies with backpack sprayers, but most can handle between 10 and 30 feet, with a minimum is 10 feet, 20 feet for average, and 30 - 35 feet for maximum. This has an impact on the cost of each sprayer. The stronger motor, the further spray. Users can consider some factors like garden size, usability, whether using for heavy-duty or just for home use,...

2. How much pressure should the pump sprayer have?

90 - 150 PSI

PSI is the unit of measurement for pressure. In the United States, the pound per square inch is the most common unit of pressure for domestic, commercial, and industrial garden equipment. For the backpack sprayers, the majority is 90-150 psi on average. Some may be able to hold more, so always check your owner's manual.

3. How many gallons does it take to cover 1000 square feet?

Most labels recommend using 1 to 2 ½ gallons of water per 1,000 square feet.

For the pesticide labels, mostly we rate 1,000 sq. ft. The difficulty is that most people are unaware of how much liquid they are spraying per 1,000 square feet. Spraying without calibration risks underapplying material and not getting the desired results, or overapplying and wasting material and money. Here are few ways to help you calculate it easily.

  • First, only use water in your sprayer, then fill to the measured mark on the side of the sprayer. On a one-gallon sprayer, this should be the one-gallon mark, and on a two-gallon sprayer, this should be the two-gallon mark. A "flat fan," even-spray tip, rather than a cone or "hollow circle," is the optimum tip for flat surface treatment.
  • Second, spray the 1,000 sq. ft. area with the sprayer you filled with water. Spray the entire area. In case it run out before covering the 1,000 sq. ft. area, it means you applying too heavily. Start a new with a lighter and faster application. One gallon of water is the bare requirement for a 1,000 square foot area.
  • Third, check the sprayer volume measurement after you've completed spraying to discover how much water is left in your sprayer. Calculate how much water you used to cover 1,000 square feet by subtracting this amount from the original volume.

For example, the amount of water you used to cover 1,000 square feet was ½ gallon. If the label specifies 4 oz/1,000 sq. ft., then you try to mix 4 oz. with ½ gallon of liquid and spray the 1,000 sq. ft. You could have used less or more, but the idea is to figure out how much water you used on a 1,000-square-foot area.

4. Are backpack sprayers safe?

Of course Yes!

Backpack pesticide sprayers are excellent garden equipment for administering pesticides and herbicides over areas. The majority of current sprayers have exceptionally high safety factor. Even many manufacturers prioritize safety when researching the sprayer feature. A few safety concerns are frequently considered, such as its easy to use, safety button, or the anti-leaking liquid while operating it,...However, to use it safely, user need to follow some operating precautions, such as

  • Always use protective equipment such as eye protection, chemical-resistant gloves, and coveralls, as well as chemical-resistant clothes and a respirator as necessary.
  • When mixing pesticides for use in a backpack, follow the instructions on the pesticide label sprayer. Use pesticides at the manufacturer's suggested rates.
  • When loading the backpack sprayer, pour the pesticide mixture through the filter basket.
  • Never use flammable liquids, acids, or caustic because of their inherent danger.

Battery Powered Backpack Sprayer Buying Guide?

Types Of Backpack Sprayer

There are two common types of backpack sprayers: a piston pump and a diaphragm pump.

  • A Piston pump: Piston sprayers have a cylinder housing in which a piston rotates up and down to create pressure when the pump is turned on. Most piston models have a maximum pressure of 90 psi. Due to its higher pressure, they are best use for long distances. It work well on produce finer droplets or a mist that covers the area well. They're perfect for spraying up into trees or larger bushes and shrubs because of the distance and finer droplets.
  • A Diaphragm pump: Diaphragm pumps have a flat diaphragm that is kept together by screws inside a housing. The diaphragm stretches up and down to create pressure when you pump. This one can reach up to 60 psi. Because there is no touch with the cylinder wall, these pumps are more robust. When spraying weeds, fencelines, and driveways, diaphragm pumps produce larger droplets that are better at getting the spray onto your target and avoiding drift.

Tank size

The size of the tank is one of the most important things to look for in any type of product, whether it’s a cheap backpack sprayer or a more expensive one. Most devices designed for commercial use feature a four-gallon tank, enough to cover the area of a small vegetable garden, lawn, or backyard.

On the other hand, products designed for industrial use will require bigger tanks of 20+ gallons as they need to cover a significantly larger surface.

No matter the size of the tank you choose, make sure it is translucent to easily see when it requires a refill. Also, look for items made of sturdy materials and with secure locks that won’t leak the chemicals out, causing rashes, irritations, or even burns on your skin.

Weight

The weight is critical factor that need to consider because the sprayer is worn on the back. Especially if you use it for a long time. Backpack sprayers are supposed to be light, the weight of your sprayer will be determined by the size of its tank. When completely loaded, most backpack sprayers weigh between 15 and 45 pounds. More capacity is beneficial, but it must be balanced against the sprayer's weight. Some people will find operating a machine with a total weight of 40 or 50 pounds too difficult.

Pump sprayers or battery-operated models?

Most sprayers with small-sized tanks of 2-4 gallons will require you to push a pump to release the substances through a hose. These products are the most popular because they are used to cover medium surfaces.

However, sprayers used for industrial purposes or needed to cover a large area will require the help of a battery that makes pumping easier, without causing hand fatigue when operating them. Usually, the battery is rechargeable and lasts for a couple of years, depending on how often you use the sprayer.

Accessories

Nozzles, hoses, and pockets for storing all accessories are key elements of a good sprayer. They help regulate the pressure and allow you to choose between a fine mist or a full stream, depending on the type of surface you need to spray.

It would be best to store all these accessories with the sprayer to occupy less space and deliver a compact design. Thus, try opting for sprayers that feature special pockets and compartments for batteries, hoses, and nozzles.
