Buying guide to buying a backpack sprayer

Factors to Consider When Picking a Backpack Sprayer

Main Usage:

What is the primary intended use of your knapsack sprayer? For example, if you are utilizing generally oil-based providers (e.g., for woody plant control) you will require sprayer seals, hoses and pumps that are resistant to oil-based providers. Knapsack sprayers require to be durable particularly with several applicators using the same devices!

Manual or Motorized (battery-powered) Sprayer:

Manual sprayers are recommended for dealing with brand-new invasions. Search for backpack sprayers that allow an applicator to switch the handle for both right and left hand operation. A sprayer that is motorized might be more convenient if you are dealing with big locations since you do not require a hand pump to maintain pressure. Nevertheless, motorized sprayers are normally more expensive, include additional weight, and need more maintenance than manual sprayers. A central component of motorized sprayers is the battery. If you decide to acquire a motorized unit, make sure that the battery can manage both low and high sprayer psi output and will work for a minimum of 3 to 5 hours without charging.

Type of Pump:

The majority of sprayers will feature either a piston or diaphragm pump. The piston-type pump is less expensive than diaphragm pumps, but may not be suitable for all types of herbicides. If you are utilizing dry-flowable or other dry herbicide formulations, the piston pump may wear faster and need replacement. In general, a diaphragm pump was chosen more often by our readers for ease of repair work and sturdiness with different formulas of herbicides.

Convenience and Safety (minimize the danger of herbicide direct exposure):

Little functions like a complete size pump handle and spray wand grip help in reducing operator fatigue. Adjustable, chemical resistant padded straps and a contoured tank offer a more comfortable fit. If the harness is not appropriate but you like other functions of a sprayer, a cushioned harness might be bought individually for some sprayers (see devices below). Look for Viton type rubber seals that resist swelling and softening, which is frequently the cause of leakage and pump breakdown.

Spray Wand:

A quality spray wand is less vulnerable to leakages and is essential for operator convenience and accurate application. Search for wands that accept the TeeJet nozzles and caps, which permit you to select from a large assortment of commercial-grade ideas that are sold by regional providers.

Sturdiness and Relieve of Repair work:

The backpack sprayer tank ought to be composed of high-density polyethylene with UV defense. Hoses, seals and other accessories should be rated for herbicides and additives you will be using. Repair work parts must be offered to rebuild components such as pumps.

Your Garden Size

While you can technically utilize any type of sprayer in any garden, the size limitations will still decrease or accelerate the job you’re doing. A sprayer with a tiny tank and/or battery life will fight with huge open spaces, whereas an oversized sprayer might be harder to utilize in very compact gardens with lots of architecture to bump into. Picking a sprayer of the suitable size will nearly lead to a far better experience, so it’s worth taking into consideration.

Remember that storage is also crucial. If you wind up puncturing the hose or tank, you’ll need to get it repaired, and incorrect storage can do this much faster than you might expect. If your home (or automobile, if you’re utilizing the sprayer for work functions) doesn’t have much storage area, attempt to go for a smaller sized model, just in case.

The purpose of buying the backpack

Not all sprayers are created to do everything, and some will be better at providing specific chemicals or spraying in certain ways. Make certain you understand what kind of tool you’re purchasing before you make the purchase given that you can wind up breaking or harming a backpack sprayer if you’re using it in an unintended way.

In a related vein, some backpack sprayers will have low pressures and PSI levels, suggesting that they output very weak and mild sprays for saturating smaller locations at a slower speed. The greater the PSI, the more violent the spray will be, which is outstanding for long-distance work however can harm the yard up close.

Even designs with adjustable pressure levels will generally still have a “suggested” quantity of pressure they need to be utilized, which can determine the kind of design choices and functions that they offer.


One of the most popular functions in any backpack sprayers is the fact that, as the name recommends, you can carry it on your back. However, not every style sets out to achieve this well, and a poor-quality model might even be designed in a way that causes physical pain or contusions after extended periods of use. Weak straps made of thin products can likewise snap easily, particularly if the tank is full, which can cause long-lasting damage to the internal structure of the unit or perhaps outright break it.

There’s also a much more severe problem of back assistance. If you’re using your backpack sprayer regularly, whether that’s around your home or as part of your task, you’ll require the very best physical support possible to make certain that your body does not suffer any long-lasting posture damage or other kinds of physical damage. The bigger the tank, the more weight will be placed on your back, so weaker or physically frail users ought to constantly search for a model that’s a comfortable weight.

Bear in mind that you do not necessarily have to fill the tank. If you have a hard time to evaluate just how much water you’ve taken into the sprayer, a clear tank might be much easier to utilize, since you can quickly translucent the outside layer instead of having to browse the mouth of the tank.

Maintenance Tips for backpacks:

Comprehensive cleansing after every usage is important for the longevity of a backpack sprayer. Your knapsack sprayer will last longer and need less repair work if you rinse the equipment completely at the end of the day with tidy water or a commercial tank cleaner.

Lube seals and o-rings periodically (at least once annually).

In colder climates, you require to winterize your sprayer before storage. Be sure to add either automotive or Recreational Vehicle antifreeze to prevent damage due to freezing. Automotive antifreeze is less corrosive to spray equipment pumps and seals than Recreational Vehicle antifreeze. Nevertheless, automobile antifreeze is toxic and must be gathered for reuse or disposed of appropriately. RV antifreeze is non-toxic and may be sprayed on the ground.
