The Best Back Sprayer: Buying Guide

Pounds Per Square Inch (PSI)

Pounds per square inch is the term you use to refer to measure the amount of sprayer can produce through the nozzle. The PSI for a backpack sprayer averages 70PSI, but some smaller models can produce 40PSI. The large brands can go as high as 150PSI. The correct PSI is vital because it determines your effectiveness at applying a specific product. Thus, the PSI level is directly dependent on the performance of your chosen backpack sprayer. If you have a yard with hard to reach locations, then go for a sprayer with a rating of 70 PSI or above. If you have an average or small-sized yard, then go for something that can provide between 40 to 80 PSI of power.

Piston vs. Diaphragm

Backpack sprayers are available in two popular types, with each having a unique delivery method. They include:

  • A piston pump – this type works to draw liquid from the tank and directs it to an enclosed section on your sprayer's upstroke. Thus, it works to direct the liquid out through unique outlet valves or nozzles when it performs the downstroke. More so, piston pump sprayers are popular because they are simple to use and maintain.

  • A diaphragm pump – these types are designed to provide optimal safety, especially when it comes to applying potent garden chemicals. Usually, they have a sealed system that can move liquid from one side, with one section of the sprayer being full, while the other sits empty. Even if a diaphragm pump won't produce the same power as a piston pump, it still works perfectly for delicate applications.

Type: Manual vs. Motorized

In most cases, backpack sprayers consist of an internal pump, which moves to move your product, through a hose, and to the nozzle. Usually, you can operate the pumps manually, or through the use of a motorized mechanism.

The manual types function through a hand pump, which is integrated into the chamber of the sprayer. While these types are often compact, they are suitable for small areas such as yards or sporadic jobs. It's not suited for intensive applications such as for professional service providers. Pumping manually for long durations requires lots of strength, and can cause fatigue. 

Furthermore, the motorized types operate through a battery or gas. The good thing about these types is that they are simple to set up and versatile. Also, a motorized sprayer will pump the product from the chamber to the wand. Your role, in this case, is to direct the wand.

Tank Capacity

Sprayers are available with varying tank capacity sizes. Usually, the compact types are available with a handle for portability, while the heavy-duty types come with wheels. Plus, the types that fall in between these two classifications are reliable sprayers. Why? They are compact, and simple to carry around for the common product application procedures.

Auxiliary Features

Remember that backpack sprayers are available with many different features. These include in-built pressure gauges, which you can use to regulate the pressure of the sprayer. Furthermore, some come with ergonomic structures, whereby user comfort is a guarantee. Some brands even include benevolent additions to their products to make your user experience unique. For instance, some brands include additional items such as sheaths, long hoses, and more. These are all reliable signs of a good sprayer for your needs.

The Design of the Backpack Sprayer 

In most cases, sprayers are available in high-density plastic materials, with tanks that pressurize the sprayer product. The pump works to compress air, which causes the pump to produce the product through a want. Usually, the sprayers come with unique wands, which you can use to control product applications' quality. More so, some types are either battery, manual, or pump operated. 

The type of sprayer you want to settle for depends on various factors, including your needs and your chosen area's size. A power sprayer – these types are ideal for spot applications of the product, or if you perhaps have to cover large areas. Plus, they are also excellent for people with physical challenges such as back problems.

Features of the Best Backpack Sprayer

  • Weight – a good backpack sprayer is not heavy or overly compact as well. In particular, anything that falls between 4 to 9lbs should be adequate for your needs. 

  • Nozzles – ensure you check the availability of wands, as this will make it easy to customize the application of products. Also, check if the wand is easy to attach to your chosen nozzle.

  • Tank size – a large tank can be bulky, while a small one can be inconveniencing. Thus, go for anything between 4 to 9 gallons, which are perfect for the product's regular applications. 

  • Motor power – remember to check the performance and efficiency of the motor in your chosen backpack sprayer. It should be powerful enough to help you tackle large scale jobs in the garden.

  • Ergonomic features – also, a good sprayer has excellent ergonomic features to make it simple to use. These can include padded straps, contoured handles, and more.
