However, you should know that these factors depend majorly on what kind of particular needs. The best place to begin is by looking at the purpose and the main type of sprayer you will be using. Here are some of the factors:

There are mainly two types of backpack sprayers:

A piston pump sprayer can be an identifier with its up and down movements. It generally generates greater pressure, almost around 90psi, and higher than a diaphragm pumps, the other type of sprayer.

With that being said, it usually sprays far distances which are perfect for tall trees and far to reach plants. This type of backpack sprayer tends to be cheaper compared to other types. The reason why it is inexpensive is due to the fact that it cannot be used for a certain type of chemicals that might destroy the piston.

Diaphragm Pump Sprayer

A diaphragm pump, on the other hand, is a more pricey option and they function almost the same way as the previous type. They are built-in with high-quality materials that are resistant to different chemicals.

Therefore, if you are using anything corrosive substance or solution, this is exactly what you need to purchase. When it comes to generating pressure is it usually done by pumping the handle and it gives more effective and quicker pressure.

The motorized Backpack sprayers, on the other hand, are ideal for larger sized areas. You will be able to treat that area effectively gaining both time and effort. The best thing about these sprayers is that you don't need to continually pump the handle. However, they are usually heavier than the manual ones.

Piston Vs Diaphragm Backpack Sprayers: What’s the difference? Which one to Pick?

When you are out looking for anything, you come across many types of it, don’t you? Similarly, when you are out looking to buy the best backpack sprayer for yourself, you will find yourself choosing between a piston and a diaphragm backpack sprayer. The question is what are they? how do they differ? Which is better and which one should you choose?

Let’s find out the answer to all these questions.

Piston Backpack Sprayers

As you can imagine the piston backpack sprayers use a piston to create pressure. Apparently, this kind is capable of creating a lot of pressure, more than the diaphragm ones. This type of sprayer comes with a cylinder within which the piston resides and the piston moves up and down to create pressure.

As a result, there is contact between the cylinder wall and the piston which makes it a bit less durable. However, it is capable of producing around 90 PSI of pressure which is quite incredible. Furthermore, it has parts that are easy to access.

It may not be durable but it is easy to repair or modify. Above all that, it is very affordable. You just have to make sure you do not put in any harsh chemical wettable powders, abrasive or bleach solutions.

Diaphragm Backpack Sprayers

These backpack sprayers are not very different in how they function from the piston sprayers. Apparently, this one also uses pressure but it uses a diaphragm that moves up and down to create pressure rather than a piston. Furthermore, it operates in a housing held together by screws.

Thus, the diaphragm does not come in contact with the wall of the container easily. As a result, this type is much more durable than the piston sprayers. In fact, it is a much-needed feature as these sprayers are not easy to fix or modify- the parts are not equally easy to reach.

Another key point that makes it different from the piston sprayers is the fact that it can create a much lower pressure- 60 PSI maximum. Other than that, these sprayers are way more capable of dealing with chemicals.

It can handle the harsher, abrasive bleach chemicals that the other type cannot handle.

Which one will you choose?

Choose the Piston Sprayers when:

  • You need a high amount of pressure when you are spraying.
  • If you want to repair or modify the sprayer easily to use it in any way you want.
  • In case you need something affordable.

Choose the Diaphragm Sprayers when:

  • A lower amount of pressure won’t harm you.
  • You need to use harsher chemicals that would otherwise harm the piston sprayers.
  • You can handle a higher price.
  • In case you need something more durable.

 Best Backpack Sprayers: Picking the Right One for your Needs 

There are a number of things you have to consider when you are buying a backpack sprayer. Let’s check these things out.

The Type of Backpack Sprayer you need 

You already know that you have to choose between a piston and a diaphragm sprayer. Furthermore, you know which one is good for what. Now, you have to consider another type- manual or motor.

As you can imagine, the motor sprayers will reduce the load on you. Therefore, they are suitable when you have to deal with a large area of land. Otherwise, a manual will be fine if you are comfortable with it.

The choice depends on what you are comfortable with and the amount of work you need to do.

The Tank Size 

The tank or cylinder will come with the sprayer obviously and you have to make sure it is of the right size. Now, the right size depends on the size of the area you will be working on. The larger the cylinder, the longer you can go without needing to refill.

But, there is another consideration. Since you will have to carry the sprayer on your back, you need it to be lightweight enough for you to carry it. Therefore, you have to find the midpoint between a reasonable weight and a good capacity. You will usually find the capacity in gallons.

The Seals and Gaskets 

You will be keeping liquid and spraying it with the sprayer. Therefore, you cannot afford leaks or lose points. Thus, you will have to check the various seals and gaskets on the unit. Firstly, check that it has the right number of them. Secondly, check that they are both efficient and effective.

Furthermore, seals and gaskets vary based on the chemical you use. Therefore, make sure that the seals and gaskets are right for the type of chemical you plan to use.

The Nozzles 

These are another important consideration as they make the whole process convenient for you if chosen right. You need to spray the chemical in various ways and in various places. In fact, you need to reach those places right and be accurate as well.

And, nozzles play a huge role in these and so does the hose. Apparently, there are various nozzles available for various kinds of jobs. If you are going to spray only in one way, a nozzle best suited for your job will do.

However, if you need to be versatile, then you need interchangeable nozzles. Then, you can just spray around just the way you need to. 

The style and comfort of the backpack sprayer 

You will be carrying the backpack sprayer on your back and that is not as easy as you think it is. Because the tank has quite a lot of weight and it can get tiresome after you have sprayed for a while. Thus, you need to feel comfortable.

The main part where you can expect some comfort is the straps of the backpack. They should distribute the weight equally and should also be adjustable. Other than that, padding in the straps will keep you out of harm’s way.

Chest or back straps can come handy in this case as well. Just choose a design that supports you wherever you need it to.

The durability of the sprayer 

You will be exposing the tank to harmful chemicals. In fact, you will be exposing the whole sprayer and yourself to harmful chemicals. You cannot afford leaks or anything of the like in this case.

Therefore, choose a material that is very resistant to corrosion and also harsh chemicals. Choose a strong material- preferably hard plastic. Other than that, make sure the smaller parts fit well, do not get loose or do not break easily. You should always be wary of leaks in this case.


Best Backpack Sprayer Brand

When you are out looking for a backpack sprayer you will be hit by the numerous brands available. It will be extremely hard to choose one over the other but there certainly are aspects in which each of them performs better. Let’s get to know the five best brands in this sector.
