Factors to consider when buying a backpack sprayer

There are a lot of types and brands of backpack sprayers in the market, such that it can be quite challenging to narrow down choices and pin point which one to purchase. For the inexperienced when it comes to back pack spraying, it will be helpful to know what features to look out for before making a purchase decision.

Here are the factors to consider when choosing a backpack sprayer:

  1. Main Objective. This is the foremost factor to consider when picking the right backpack sprayer to suit your needs. You must know your objective when buying a backpack sprayer. It is important that you know why you are buying, what applications you will be using it for.
  2. Type of Chemical to be used. There are quite a number of chemicals that are used in backpack sprayers and some could be corrosive. While the usual Piston-Style pump can be greatly pressurized, it is not meant for abrasive solutions and harmful chemicals found in some herbicides as these can contribute to its corrosion. Powdered formula likewise cannot be used on Piston-type pumps.
  3. Type of plant to spray on. When one needs very targeted applications, then Piston-type pumps can be very useful. Targeted applications ensure that the chemicals and liquid gardening or farming formulas are absorbed by the plant. Moreover, it helps in efficiently dispersing chemicals. At the same breath, wide spraying such as those in weeds, may be great for diaphragm type sprayers.
  4. The area where the backpack sprayer will be used. The bigger the area, the bigger the capacity of sprayer one will need. A bigger-capacity backpack sprayer will be more convenient for the user since he will not have to go back and forth refilling his tank with liquid or powdered spray formulations just so to cover the whole lawn, garden, farm or mini orchard. The caveat here though is If one gets the biggest tank available, the tank’s weight can strain the body in the long run.
  5. The Budget. People have unique budget considerations when it comes to purchasing any product. The good news is that there is a good sprayer for every price point. Of course it will depend on where the sprayer is manufactured, the materials used and the durability. A good trick in finding the best sprayer for one’s budget is to determine the amount you are willing to pay for, and then find the sprayers in that price range.
  6. Preference for Manual or Battery Powered Pump. Of course manual pumps are cheaper but repetitive movements may cause strain after sometime. Battery powered pumps are very convenient to use but depending on the battery capacity of the pump it can be quite disruptive when the battery runs out prior to completing the spraying activity. It is important then to make sure that the battery capacity can last the same time it will be used.
  7. Weight and Capacity of the tank. Back Pack Sprayers are usually sold in two, four and six gallon volume capacity. If you have a small garden then a two gallon back pack sprayer tank can be a good choice. The maximum capacity tank of six gallons meanwhile can help ensure that you will not be refilling every now and then, but then carrying a back pack that heavy can strain one’s back and be achy to the whole body. Moreover, it may constrain the user to use more spray liquid than what is really needed.  
  8. Length of time a backpack sprayer will be used per session. This will determine the capacity, and battery power requirements of the back pack sprayer about to be purchased.
  9. Ease of Use. One has to try on the backpack sprayer or at least check out web videos of reputable reviewers on how to use the backpack sprayer and how easy it is to put on and operate.
  10. Comfortability. Ergonomic design is a huge plus when it comes to choosing the right back pack sprayer. Imagine having something on your body the whole day? Of course it would be best to choose one that will not strain your back, neck, and hand muscles. Thankfully, there are a lot of Backpack sprayer manufacturers that have considered this feature.
  11. Special Features. It would be best if the Backpack Sprayer of your choice comes with added or special features that will increase usage convenience. Some have extra nozzles that have varied use, some come with extra parts or extended sprayer hose.
